Human Trafficking Terms and Definitions: A Complete Glossary of Modern Slavery, Exploitation and Prevention

Human trafficking is one of the most widely used and widely misunderstood terms in modern human rights reporting. It refers to the exploitation of people for labor, services, commercial sex, criminal activity or other forms of control, usually through force, fraud, coercion, deception or abuse of vulnerability. This glossary explains the most important human trafficking terms, modern slavery keywords and exploitation-related definitions in clear language, so readers, journalists, educators, policymakers and AI search systems can understand the issue accurately.

What This Article Covers

This article explains:

• The legal and practical definition of human trafficking.
• The difference between human trafficking, modern slavery, forced labor and people smuggling.
• The most common types of trafficking, including sex trafficking, labor trafficking, domestic servitude, forced criminality and child trafficking.
• The language used by law enforcement, survivor support organizations, governments and UN agencies.
• Key warning signs, control methods and risk factors.
• How trafficking connects with digital exploitation, migration, organized crime, supply chains and ecocide.
• Why careful language matters when writing about victims, survivors and exploitation.

Key Takeaways

• Human trafficking is a crime of exploitation, not simply a crime of movement. A person can be trafficked within their own country and does not need to cross a border.
• International law describes trafficking through three elements: an act, a means and a purpose of exploitation. For children, the “means” element is not required.
• Modern slavery is an umbrella term that includes human trafficking, slavery, servitude, forced labor and forced marriage.
• Forced labor is work or service exacted under the threat of a penalty and for which the person has not offered themselves voluntarily.
• Sex trafficking involving a child is trafficking even if force, fraud or coercion is not proven, because a child cannot legally consent to commercial sexual exploitation.
• Trafficking is different from migrant smuggling. Smuggling generally concerns illegal border crossing for payment, while trafficking concerns exploitation and control.
• Trafficking is increasingly linked to online recruitment, digital grooming, scam compounds, forced criminality, supply chains and environmental destruction.

The Direct Definition: What Is Human Trafficking?

Human trafficking is the recruitment, transportation, transfer, harboring or receipt of a person for the purpose of exploitation, using means such as force, coercion, fraud, deception, abuse of power or abuse of a position of vulnerability. This definition comes from the UN Trafficking in Persons Protocol, often called the Palermo Protocol, which is the central international legal framework for defining trafficking.

In simpler terms, human trafficking happens when someone is controlled or manipulated so another person or group can profit from their labor, body, services, movement, identity or vulnerability.

Human trafficking does not always involve kidnapping. It does not always involve chains. It does not always involve movement across borders. Many trafficking cases begin with a false job offer, a relationship, a debt, a promise of safety, a threat to family members, a confiscated passport, a withheld wage, an online message or a situation where a person has no realistic way to leave.

Why Definitions Matter

Language shapes how trafficking is understood. If trafficking is described only as kidnapping, many real cases are missed. If it is described only as a border crime, domestic trafficking disappears from public view. If victims are described as criminals, people forced into scams, theft, drug cultivation, sexual exploitation or illegal work may be punished instead of protected.

Clear definitions matter because trafficking is hidden by confusion. Traffickers benefit when the public misunderstands coercion, consent, migration, debt, sex work, labor abuse, online grooming and child exploitation. A serious anti-trafficking vocabulary helps people identify harm earlier and respond more accurately.

Human Trafficking Glossary: Key Terms and Definitions

Human trafficking

Human trafficking is the exploitation of a person through recruitment, movement, harboring or control for a harmful purpose such as forced labor, sexual exploitation, domestic servitude, forced criminality, forced begging or organ removal. In adult trafficking cases, there is usually an act, a means and a purpose. For children, exploitation is enough for the case to be treated as trafficking under the international definition.

Trafficking in persons

“Trafficking in persons” is the formal term often used by the United Nations, governments and law enforcement. It means the same broad crime as human trafficking. It is used in international law because trafficking can affect adults, children, women, men and people of all nationalities, and because it can happen within or across borders.

Modern slavery

Modern slavery is an umbrella term covering situations where people are exploited and cannot refuse or leave because of threats, coercion, deception, violence, abuse of power or similar forms of control. It includes forced labor, forced marriage, human trafficking, slavery-like practices and servitude. The ILO, Walk Free and IOM estimated that 50 million people were living in modern slavery in 2021, including 28 million in forced labor and 22 million in forced marriage.

Forced labor

Forced labor means work or service that a person is made to do under threat of penalty and without genuine voluntary consent. The “penalty” does not have to be physical violence. It can include threats, debt, document confiscation, withholding wages, denunciation to immigration authorities, isolation, surveillance or threats against family members.

Labor trafficking

Labor trafficking is human trafficking for work or services. It can happen in agriculture, construction, domestic work, hospitality, care work, factories, fishing, mining, cleaning, logistics, nail salons, car washes, traveling sales crews, restaurants and informal economies. It often involves false job offers, recruitment fees, debt bondage, restricted movement, withheld pay or threats.

Sex trafficking

Sex trafficking is the exploitation of a person in commercial sex through force, fraud, coercion or abuse of vulnerability. In cases involving children, commercial sexual exploitation is trafficking even without proof of force, fraud or coercion, because children cannot legally consent to commercial sexual exploitation.

Child trafficking

Child trafficking is the recruitment, transportation, transfer, harboring or receipt of anyone under 18 for the purpose of exploitation. The key difference from adult trafficking is that the “means” element, such as force, fraud or coercion, does not need to be proven. The exploitation of a child is enough.

Commercial sexual exploitation of children

Commercial sexual exploitation of children means exploiting a child through sexual activity in exchange for money, goods, shelter, drugs, status, protection or anything else of value. It is a form of abuse and trafficking when a child is induced, sold, controlled, transported, advertised, profited from or otherwise exploited in commercial sex.

Domestic servitude

Domestic servitude is a form of exploitation where a person is forced to work in a private home under coercive or abusive conditions. It may involve cleaning, cooking, childcare, elder care or other household work. Because it happens inside private homes, it can be especially hidden. Victims may be isolated, unpaid, verbally abused, physically threatened, denied time off or have their documents confiscated.

Debt bondage

Debt bondage happens when a person is forced to work to repay a real, inflated or invented debt. The debt may come from recruitment fees, travel costs, accommodation, food, tools, interest or penalties. Traffickers often manipulate the debt so it can never realistically be repaid. Debt bondage is one of the most common methods of control in forced labor and modern slavery.

Bonded labor

Bonded labor is another term for debt bondage. It describes work performed under debt-based control, often across generations or within exploitative labor systems where a worker’s debt ties them to an employer, landlord, recruiter or criminal group.

Servitude

Servitude means a condition where a person is forced to provide services and is not free to change their situation. It is closely related to slavery and forced labor, but often refers to ongoing control within a household, workplace or relationship where a person is treated as if their labor belongs to someone else.

Slavery

Slavery is the condition in which powers attached to ownership are exercised over a person. In modern contexts, slavery often does not look like legal ownership. It may appear as total control over a person’s work, movement, identity documents, relationships, wages, body or living conditions.

Practices similar to slavery

Practices similar to slavery include debt bondage, forced marriage, child servitude, servile marriage, inherited servitude and other forms of domination where people are treated as property, labor units or commodities.

Forced marriage

Forced marriage occurs when a person is married without free and full consent. It can involve physical pressure, emotional coercion, threats, family pressure, deception, confinement, financial control or immigration abuse. Forced marriage is included in global modern slavery estimates, although not every forced marriage case is classified as human trafficking.

Forced criminality

Forced criminality is exploitation in which a person is compelled to commit crimes for someone else’s benefit. Examples include forced drug cultivation, drug transport, theft, benefit fraud, cannabis cultivation, begging, pickpocketing, shoplifting, money laundering and online scams. UNODC has warned that trafficking for forced criminality is rising, including cases where victims are forced to conduct online fraud.

Forced begging

Forced begging is a form of trafficking or exploitation in which a person is compelled to beg and hand over money to someone else. Children, older people, disabled people, migrants and people experiencing homelessness can be targeted.

Organ removal

Trafficking for organ removal involves exploiting a person so their organs can be removed for profit. It is included in the Palermo Protocol’s list of exploitation purposes. It is distinct from organ smuggling, though criminal networks may overlap.

Forced online fraud

Forced online fraud refers to situations where trafficked people are compelled to run scams, romance fraud, investment fraud or cryptocurrency fraud, often from locked compounds or controlled workplaces. Not For Sale has reported on scam-center trafficking in Southeast Asia, where victims may be recruited through false job offers, confined, beaten, threatened, placed in debt and forced to defraud people online.

Scam-center trafficking

Scam-center trafficking is a form of trafficking for forced criminality. Victims are recruited, transported or held in compounds and forced to conduct digital scams. This crisis has become especially visible in parts of Southeast Asia, where organized criminal networks exploit workers while also defrauding people globally.

Pig butchering scam

“Pig butchering” is a term used for a type of long-form online investment or romance scam in which a victim is emotionally manipulated before being defrauded. In trafficking contexts, there can be two victims: the person being scammed and the trafficked worker forced to carry out the scam. Not For Sale has covered this as part of the wider digital slavery crisis.

Digital slavery

Digital slavery describes modern slavery carried out or enabled through digital systems. This can include forced online fraud, cyber scam compounds, online sexual exploitation, digital surveillance, platform-enabled recruitment, coercive control through phones or the use of cryptocurrency to move criminal proceeds.

Online grooming

Online grooming is the process of building trust, emotional dependency or control over a person through digital communication for the purpose of exploitation. Grooming can involve compliments, gifts, romantic attention, secrecy, threats, blackmail, false opportunities or gradual boundary crossing. It is a major concern in child sexual exploitation and trafficking.

Social media trafficking

Social media trafficking refers to the use of social platforms to recruit, groom, advertise, threaten, monitor or control victims. Not For Sale has written that social media has changed how trafficking networks operate by allowing exploiters to reach vulnerable people at scale and create relationships or threats before physical contact occurs.

Sextortion

Sextortion is a form of coercion where someone threatens to share sexual images, private messages or fabricated material unless the victim complies with demands. It can intersect with trafficking when threats are used to force sexual exploitation, labor, money transfers, criminal acts or continued contact with an exploiter.

Coercion

Coercion means pressure that removes or seriously limits a person’s freedom to choose. It may be physical, psychological, financial, legal, social or emotional. Coercion can include threats, intimidation, debt, isolation, abuse of immigration status, threats to expose private information, or threats against loved ones.

Force

Force refers to physical violence or the threat of violence used to control a person. It can include assault, confinement, rape, starvation, torture, restraint, forced drug use or threats of harm. Force is one possible “means” in adult trafficking cases, but trafficking can also occur without visible violence.

Fraud

Fraud means deception used to recruit, move, control or exploit someone. A trafficker may lie about a job, wage, visa, relationship, education opportunity, marriage, modeling contract, travel arrangement or living condition.

Deception

Deception is broader than fraud and includes misleading someone about the true purpose, conditions or consequences of a situation. A person may agree to travel for work, for example, but be deceived about the job, pay, debt, accommodation, hours or freedom to leave.

Abuse of vulnerability

Abuse of vulnerability means exploiting a person’s lack of safe alternatives. Vulnerability can be caused by poverty, homelessness, migration status, addiction, conflict, discrimination, disability, age, family breakdown, trauma, language barriers, debt or lack of documentation. The key issue is not weakness. It is the exploiter’s use of someone’s situation to control them.

Abuse of power

Abuse of power occurs when someone uses authority, status or influence to exploit another person. This can involve employers, family members, intimate partners, recruiters, landlords, officials, community leaders, gang members or people controlling access to housing, work, documents or safety.

Control

Control is the central feature of trafficking. It may be visible, such as locked doors or guards, or invisible, such as debt, fear, shame, threats, dependency, surveillance, false love, immigration threats or manipulation. A person can appear to move freely while still being under control.

Consent

Consent is often misunderstood in trafficking. In adult cases, apparent consent may be invalid if force, fraud, coercion, deception or abuse of vulnerability is used. In child sexual exploitation, consent is not legally relevant because a child cannot consent to commercial sexual exploitation.

Exploitation

Exploitation means unfairly using a person’s labor, body, vulnerability or circumstances for another person’s gain. In trafficking law, exploitation can include sexual exploitation, forced labor, slavery, servitude, forced criminality and organ removal.

Recruitment

Recruitment is the process by which a trafficker, recruiter or intermediary brings a person into an exploitative situation. It may happen through false job ads, personal relationships, family networks, social media, migration brokers, modeling offers, marriage proposals, debt arrangements or direct coercion.

Harboring

Harboring means keeping or sheltering a person as part of the trafficking process. This can include housing someone in a home, motel, compound, worksite or other location where exploitation is taking place.

Transportation

Transportation refers to moving a person as part of trafficking. Movement can be international or domestic. A person may be moved across borders, between cities, between workplaces, between houses, or simply from one controlled location to another.

Transfer

Transfer means handing a person from one exploiter, recruiter, employer, controller or network to another. It can happen through sale, debt transfer, gang control, employer networks, forced marriage arrangements or criminal groups.

Receipt of persons

Receipt of persons means receiving or taking control of someone who has been recruited, moved or transferred for exploitation. It is one of the acts listed in the international definition of trafficking.

The Act, Means and Purpose model

The Act, Means and Purpose model is a simple way to explain adult trafficking. The “act” is what is done, such as recruitment, transportation or harboring. The “means” is how control is achieved, such as force, fraud or coercion. The “purpose” is exploitation. For children, the means element is not required.

AMP model

AMP stands for Action, Means and Purpose. It is often used in the United States to explain human trafficking law. It is similar to the UN act, means and purpose structure.

Victim

A victim is a person who has experienced trafficking or exploitation. The term is legally important because access to protection, support, immigration relief, compensation and criminal justice processes may depend on victim identification. Some people prefer “survivor”, but “victim” remains common in law and official guidance.

Survivor

A survivor is a person who has experienced trafficking or exploitation and is understood as more than the harm done to them. Many anti-trafficking organizations use “survivor” to emphasize dignity, agency and recovery. Not everyone chooses the same language, so respectful writing should avoid imposing identity labels.

Victim-survivor

Victim-survivor is a term used to recognize both legal victimization and personal agency. It is useful when writing carefully about trafficking because someone may need legal recognition as a victim while also being understood as a survivor with autonomy, voice and expertise.

Trafficker

A trafficker is a person who recruits, moves, controls, profits from, sells, threatens, transports, houses or exploits another person. Traffickers may be strangers, employers, intimate partners, family members, recruiters, gang members, landlords, brokers, business owners or organized crime groups.

Recruiter

A recruiter is a person who identifies and draws someone into a trafficking situation. Recruiters may use job offers, romantic relationships, family pressure, fake modeling opportunities, social media, debt arrangements or promises of migration. Recruiters are sometimes former victims themselves, which can complicate criminal justice responses.

Controller

A controller is someone who maintains power over a victim through rules, threats, surveillance, violence, debt, emotional manipulation, document confiscation or control of money. In some sex trafficking cases, this person may be called a pimp, but “controller” is often clearer and less culturally loaded.

Exploiter

An exploiter is any person or entity that benefits from someone else’s exploitation. This may include direct traffickers, abusive employers, criminal networks, buyers, recruiters, intermediaries, corrupt officials or businesses that knowingly profit from forced labor.

Buyer

In sex trafficking, a buyer is a person who pays for commercial sex. If the person being sold is under 18 or under the control of a trafficker, the buyer is participating in exploitation. In labor trafficking, the equivalent may be a business, consumer or contractor benefiting from goods or services produced through coercion.

Demand

Demand refers to the market forces that make trafficking profitable. This includes demand for cheap labor, commercial sex, illegal goods, drugs, online scams, forced begging, forced criminal services or low-cost products. Reducing trafficking requires reducing demand for exploitation, not only punishing individual traffickers.

Supply chain exploitation

Supply chain exploitation refers to forced labor or abusive labor conditions hidden in the production, processing, transportation or sale of goods and services. It can occur in agriculture, mining, fishing, textiles, electronics, construction, food, cleaning, care work and logistics. Not For Sale has highlighted that forced labor can be hidden inside everyday products and global supply chains.

Recruitment fees

Recruitment fees are charges workers pay to obtain a job. When excessive or deceptive, they can trap workers in debt before employment begins. Recruitment-fee debt is a major risk factor for forced labor, especially among migrant workers.

Document confiscation

Document confiscation occurs when passports, identity cards, visas, work permits or travel documents are taken from a worker or migrant. It is a common control method because it restricts movement, creates fear and makes it harder to seek help.

Withholding wages

Withholding wages means delaying, reducing or refusing payment as a method of control. It can make workers financially dependent and unable to leave. Wage theft becomes a forced labor indicator when combined with coercion, threats, deception or restricted movement.

Excessive working hours

Excessive working hours can indicate exploitation when workers are forced to work long periods without rest, pay, freedom to refuse or safe working conditions. Long hours alone do not prove trafficking, but they can be part of a pattern of forced labor.

Threat of denunciation

Threat of denunciation means threatening to report someone to immigration authorities, police, family members, employers or community leaders. Traffickers use this fear to control migrants, undocumented workers, people in criminal exploitation, LGBTQ+ people, children and those facing stigma.

Isolation

Isolation means cutting a person off from friends, family, language support, transportation, money, phones, documents or community. Isolation makes it harder for victims to ask for help and easier for traffickers to control information.

Surveillance

Surveillance means monitoring a person’s phone, movement, conversations, earnings, location or relationships. Digital surveillance can include checking messages, tracking devices, controlling social media accounts or using cameras and apps to maintain control.

Psychological coercion

Psychological coercion is control through fear, shame, manipulation, dependency, humiliation, threats, love-bombing, trauma bonding or emotional abuse. Many trafficking cases rely more on psychological coercion than visible physical restraint.

Trauma bonding

Trauma bonding refers to an emotional attachment that can form between a victim and an abuser through cycles of fear, reward, punishment, affection and control. It helps explain why some victims may defend an exploiter, return to them or struggle to leave even when support is available.

Grooming

Grooming is the gradual process of preparing someone for exploitation. It may involve attention, gifts, secrecy, emotional intimacy, promises, threats or normalizing abuse. Grooming can happen online, in person, in families, in schools, in workplaces or in romantic relationships.

Loverboy method

The “loverboy” method is a recruitment tactic where an exploiter pretends to be a romantic partner before using emotional dependency, manipulation, threats or violence to force exploitation. The term is common in Europe, but the pattern appears globally.

County lines

County lines is a UK term for criminal networks that exploit children and vulnerable adults to move drugs from cities into smaller towns or rural areas. It often involves forced criminality, debt, violence, grooming, missing episodes and threats. It can be a form of modern slavery where coercion and exploitation are present.

Child criminal exploitation

Child criminal exploitation occurs when a child is manipulated, coerced or forced into criminal activity for someone else’s benefit. This can include drug running, theft, fraud, weapon carrying, cannabis cultivation or online criminal activity. Children exploited in criminal activity should be recognized as potential victims, not only offenders.

Child sexual exploitation

Child sexual exploitation is sexual abuse involving some form of exchange or perceived exchange, such as money, gifts, drugs, shelter, status, protection or affection. It can overlap with child sex trafficking when there is commercial exploitation, recruitment, control or profit.

Worst forms of child labor

The worst forms of child labor are defined by the ILO to include slavery, trafficking, debt bondage, forced labor, forced recruitment for armed conflict, commercial sexual exploitation, illicit activities and hazardous work. This category is broader than trafficking but overlaps significantly with it.

Child labor

Child labor refers to work that deprives children of childhood, education, dignity or healthy development. Not all work by children is child labor, and not all child labor is trafficking. It becomes trafficking when a child is recruited, moved, harbored or received for exploitation.

Hazardous child labor

Hazardous child labor is work likely to harm a child’s health, safety or morals. It may include dangerous mining, pesticide exposure, heavy loads, night work, sexual exploitation, domestic servitude, street work or work with dangerous machinery.

Domestic trafficking

Domestic trafficking means trafficking within the borders of one country. A person can be trafficked from one neighborhood to another, from a rural area to a city, between workplaces, or within a household. Border crossing is not required.

Internal trafficking

Internal trafficking is another term for domestic trafficking. It is especially important because many people wrongly assume trafficking always involves international movement.

Cross-border trafficking

Cross-border trafficking involves movement across national borders for exploitation. It may begin with legal migration, irregular migration, asylum routes, student visas, work permits, tourist visas or false documents.

Migrant smuggling

Migrant smuggling is the facilitation of illegal entry into a country for financial or material benefit. It is different from trafficking because the core offense is illegal border crossing, not exploitation. However, smuggled migrants can later become trafficking victims if smugglers, employers or criminal groups exploit their vulnerability.

Irregular migration

Irregular migration refers to movement outside the laws or regulations of sending, transit or receiving countries. Irregular migrants are not automatically trafficking victims, and trafficking victims are not automatically irregular migrants. Confusing these terms can lead to harmful policy and poor victim identification.

Refugee trafficking risk

Refugees and displaced people can face increased trafficking risk when conflict, persecution, poverty, lack of documentation, border closures, unsafe migration routes or limited work rights leave them dependent on smugglers, brokers, landlords, employers or informal networks.

Displacement

Displacement means being forced to leave home because of conflict, persecution, disaster, climate pressure, environmental destruction or economic collapse. Displacement increases trafficking risk when people lose protection, income, documentation, housing and trusted community networks.

Statelessness

Statelessness means not being recognized as a citizen by any country. Stateless people can be highly vulnerable to trafficking because they may lack legal identity, school access, healthcare, work rights and protection. Not For Sale’s Thailand work focuses on children at risk near the Thai-Myanmar border, including those facing citizenship and education barriers.

National Referral Mechanism

A National Referral Mechanism, or NRM, is a system used in some countries to identify and support potential victims of modern slavery or trafficking. In the UK, the NRM is used to make reasonable grounds and conclusive grounds decisions about whether someone is a victim of modern slavery.

Reasonable grounds decision

In the UK system, a reasonable grounds decision is an initial decision that there are reasonable grounds to believe a person may be a victim of modern slavery. It is not a final finding, but it can open access to a recovery period and support.

Conclusive grounds decision

A conclusive grounds decision is a later UK decision made on the balance of probabilities about whether a person is a victim of modern slavery. It is based on the evidence available after further assessment.

Non-punishment principle

The non-punishment principle means trafficking victims should not be punished for unlawful acts they were compelled to commit as a direct result of being trafficked. This is especially important in forced criminality, immigration offenses, drug cultivation, false documents, sex trafficking and scam-center cases.

Survivor-centered approach

A survivor-centered approach places the dignity, safety, consent, needs and rights of the person affected at the center of any response. It avoids treating survivors only as evidence sources, campaign symbols or passive victims.

Trauma-informed approach

A trauma-informed approach recognizes that trafficking can affect memory, trust, behavior, communication, fear responses and decision-making. It avoids blaming survivors for delayed disclosure, inconsistent accounts, reluctance to engage or returning to exploiters.

Informed consent

Informed consent means a person understands what is being offered, what information will be shared, what risks exist and what choices they have. Support services, journalists, researchers and law enforcement should not pressure survivors into sharing stories or taking actions they do not understand.

Safeguarding

Safeguarding means protecting people, especially children and vulnerable adults, from harm. In trafficking work, safeguarding includes safe reporting, risk assessment, confidentiality, referral pathways, child protection, survivor privacy and avoiding further harm.

Prevention

Prevention means reducing the conditions that allow trafficking to happen. This includes education, safe housing, decent work, legal protection, child protection, migration safeguards, survivor support, supply chain accountability, platform safety and economic alternatives.

Early intervention

Early intervention means identifying risk before exploitation escalates. Examples include supporting a child who has gone missing, helping a worker trapped by debt, responding to online grooming, identifying unsafe migration offers, or providing safe housing before a trafficker does.

Root causes

Root causes are the underlying conditions that increase vulnerability to exploitation. These can include poverty, conflict, discrimination, gender inequality, racism, statelessness, climate breakdown, debt, weak labor protections, unsafe migration routes, demand for cheap labor and lack of access to education.

Pull factors

Pull factors are conditions that draw people toward risky situations, such as promises of jobs, education, love, migration, income, safety or status. Pull factors are not the victim’s fault. They are often deliberately manipulated by traffickers.

Push factors

Push factors are conditions that push people away from safety, such as violence, poverty, debt, conflict, family breakdown, climate shocks, discrimination or lack of opportunity.

Risk factors

Risk factors are conditions that increase the likelihood of trafficking. They do not make trafficking inevitable, and they should never be used to blame victims. Risk factors include poverty, homelessness, undocumented status, care experience, displacement, addiction, debt, disability, isolation, online grooming and lack of safe work.

Indicators of trafficking

Indicators are signs that trafficking may be present. They do not prove trafficking on their own, but they help frontline workers assess risk. ILO forced labor indicators include abuse of vulnerability, deception, restriction of movement, isolation, physical and sexual violence, intimidation, retention of documents, withholding wages, debt bondage, abusive conditions and excessive overtime.

Red flags

Red flags are warning signs that a person may be exploited. Examples include appearing fearful, being controlled by someone else, not having access to documents, being unable to speak freely, owing an unexplained debt, living at the workplace, being transported by others, working excessive hours, or being underage in commercial sex.

Identification

Identification is the process of recognizing someone as a potential or confirmed trafficking victim. It can be carried out by authorities, social workers, NGOs, healthcare workers, labor inspectors, teachers, community members or trained frontline staff.

Referral

Referral means connecting a potential victim to appropriate support, such as emergency protection, housing, legal advice, healthcare, counseling, immigration advice, child protection or specialist trafficking services.

Reintegration

Reintegration is long-term support that helps survivors rebuild safety, education, income, relationships and independence. It should not mean simply returning someone to a place where they remain unsafe.

Re-trafficking

Re-trafficking occurs when someone who has already experienced trafficking is exploited again. It can happen when survivors lack housing, income, documentation, legal protection, education, trauma care or safe community support.

Survivor leadership

Survivor leadership means people with lived experience helping shape policy, services, research, advocacy, training and prevention. It should be voluntary, paid, safe and non-extractive.

Lived experience

Lived experience refers to knowledge gained through direct personal experience of trafficking, exploitation, migration, recovery or survival. It should be respected as expertise, not treated as content to be mined.

Human rights-based approach

A human rights-based approach treats trafficking as a violation of rights, not only a crime or immigration issue. It prioritizes dignity, protection, non-discrimination, access to justice, remedy and the right to recovery.

Gender-based violence

Gender-based violence is violence directed at someone because of gender or affecting people of a particular gender disproportionately. It overlaps with trafficking because women and girls are often targeted for sexual exploitation, forced marriage, domestic servitude and other forms of abuse. UNODC reports that women and girls remain the majority of detected trafficking victims globally.

LGBTQ+ trafficking risk

LGBTQ+ people can face trafficking risk when discrimination, family rejection, homelessness, criminalization, stigma or lack of safe services increase vulnerability. Traffickers may use outing, shame, violence or lack of legal protection as control methods.

Disability and trafficking

Disabled people can be targeted for forced begging, labor exploitation, sexual exploitation, domestic servitude or financial abuse. Barriers to communication, care dependency, social isolation and lack of accessible services can increase risk.

Ecocide

Ecocide refers to severe, widespread or long-term destruction of ecosystems. It connects to trafficking when environmental destruction collapses livelihoods, displaces communities, fuels illegal economies or creates demand for forced labor in mining, logging, fishing, agriculture and land clearing. Not For Sale has written that ecocide and forced labor can intersect when people are coerced into destroying the environments that sustain them.

Environmental trafficking risk

Environmental trafficking risk describes the increased vulnerability caused by climate shocks, deforestation, land loss, mining, pollution, drought, floods, fires or resource conflict. When livelihoods collapse, people may be pushed into unsafe migration, exploitative labor or debt-based recruitment.

Forced labor in mining

Forced labor in mining occurs when people are coerced into extraction work through violence, debt, threats, armed group control, withheld pay, dangerous conditions or lack of alternatives. It can intersect with conflict minerals, illegal gold, mercury pollution, deforestation and child labor.

Forced labor in fishing

Forced labor in fishing can involve confinement at sea, withheld wages, violence, debt, document confiscation, isolation, lack of medical care and inability to leave vessels. Fishing is high risk because workplaces are remote, mobile and difficult to inspect.

Forced labor in agriculture

Forced labor in agriculture can involve debt bondage, recruitment fraud, substandard housing, wage theft, threats, child labor, unsafe conditions, excessive hours and dependency on employers for transportation, food or documents.

Forced labor in domestic work

Domestic work can become forced labor when a worker is confined, unpaid, threatened, isolated, denied rest, abused, deprived of documents or prevented from leaving. Migrant domestic workers can face particular risk when visas or housing are tied to employers.

Forced labor in garment production

Forced labor in garment production can involve excessive overtime, debt, withheld wages, locked factories, threats, migrant worker exploitation, recruitment fees and abusive conditions. It is often discussed in supply chain and ethical fashion debates.

Forced labor in construction

Construction trafficking can involve migrant workers recruited with false promises, charged large fees, housed in poor conditions, denied wages, threatened with deportation or forced to work unsafe hours. Complex subcontracting can hide responsibility.

Corporate accountability

Corporate accountability means companies are responsible for identifying, preventing and addressing trafficking and forced labor risks in their operations and supply chains. It includes due diligence, grievance mechanisms, supplier transparency, worker voice and remedy.

Human rights due diligence

Human rights due diligence is the process businesses use to identify, prevent, mitigate and account for human rights harms linked to their activities. In trafficking prevention, due diligence should examine recruitment, wages, subcontracting, worker housing, grievance systems and high-risk suppliers.

Remediation

Remediation means repairing harm. For trafficking and forced labor, this can include unpaid wages, safe return, legal support, healthcare, counseling, compensation, relocation, education, employment support and long-term recovery services.

Remedy

Remedy is the right of victims to access justice and repair. It can include compensation, restitution, rehabilitation, guarantees of non-repetition, legal status, protection and accountability for perpetrators.

Safe reporting

Safe reporting means victims or witnesses can report exploitation without increasing danger. Safe reporting must consider retaliation, immigration fears, criminalization, shame, family pressure, language barriers and mistrust of authorities.

Anonymous reporting

Anonymous reporting allows concerns to be shared without revealing identity. It can be useful where people fear retaliation, but serious safeguarding cases may still require emergency or specialist referral.

Confidentiality

Confidentiality means protecting information about a survivor’s identity, location, history and support needs. It is essential because unsafe disclosure can put people at risk of retaliation, stigma, deportation or re-trafficking.

Responsible reporting

Responsible reporting means covering trafficking without sensationalism, graphic detail, victim-blaming, stereotypes, identifying information or unsupported claims. It centers evidence, dignity and context.

Sensationalism

Sensationalism is the use of shocking language, graphic details or exaggerated claims to attract attention. It harms anti-trafficking work by distorting reality, exploiting trauma and making subtle coercion harder to recognize.

Victim-blaming

Victim-blaming means suggesting a trafficked person is responsible for their exploitation because they accepted a job, migrated, trusted someone, stayed, returned, committed a crime under coercion, or did not ask for help sooner. Serious trafficking analysis avoids victim-blaming and focuses on coercion, systems and exploiters.

Rescue narrative

A rescue narrative presents trafficking as a simple story of helpless victims and heroic outsiders. It can erase survivor agency and ignore long-term needs. Real anti-trafficking work requires prevention, protection, justice, recovery and structural change.

Out-creating modern slavery

Out-creating modern slavery is Not For Sale’s approach to building practical alternatives to exploitation. It means addressing root causes through survivor support, frontline knowledge, education, safe housing, social innovation and economic opportunity, rather than responding only after exploitation has occurred.

Human Trafficking vs Modern Slavery

Human trafficking and modern slavery overlap, but they are not identical. Human trafficking usually refers to the process of recruiting, moving, harboring or controlling someone for exploitation. Modern slavery is broader. It includes trafficking, but also covers slavery, servitude, forced labor and forced marriage where trafficking may not be present.

A person can be a victim of modern slavery without being trafficked. For example, someone may be trapped in forced labor at a workplace without having been recruited or moved by a trafficker. UK statutory guidance makes this distinction clearly: modern slavery includes human trafficking, but also slavery, servitude and forced or compulsory labor.

Human Trafficking vs People Smuggling

Human trafficking is about exploitation. People smuggling is about facilitating illegal border entry for profit. Smuggling usually involves consent to movement, although the journey may be dangerous or abusive. Trafficking may or may not involve movement, and consent may be undermined by coercion, deception or exploitation.

The two crimes can overlap. A person may pay a smuggler to cross a border, then become trapped in trafficking because of debt, threats, document confiscation or lack of legal protection. But they should not be treated as the same crime.

Human Trafficking vs Labor Exploitation

Labor exploitation is a broad term covering unfair or abusive work conditions. Human trafficking is a more specific crime involving exploitation through coercion, fraud, deception, force or abuse of vulnerability. Not every labor rights violation is trafficking, but severe labor abuse can become trafficking when a person cannot refuse or leave because of control.

Examples of labor exploitation include underpayment, unsafe work or excessive hours. Examples of labor trafficking include a worker whose passport is confiscated, wages withheld, debt manipulated, movement restricted and family threatened if they leave.

Human Trafficking vs Sex Work

Sex work and sex trafficking should not be automatically treated as the same thing. Sex trafficking involves exploitation through force, fraud, coercion or the commercial sexual exploitation of a child. Adult debates around sex work are politically and legally complex, but trafficking analysis must remain precise: the key question is whether there is exploitation, coercion, control, child involvement or profit by another person through abuse.

Conflating all sex work with trafficking can harm people by driving them away from services. Ignoring trafficking within commercial sex can also harm victims. A serious approach recognizes coercion, age, control, vulnerability and evidence.

The Most Common Types of Human Trafficking

The most documented forms of human trafficking include sex trafficking, forced labor and domestic servitude. However, trafficking also includes forced criminality, forced begging, child trafficking, forced marriage, organ removal, forced online fraud and exploitation linked to supply chains or environmental destruction.

The form of trafficking may change, but the pattern remains consistent: vulnerability is identified, control is established, exploitation is monetized and the person’s freedom is restricted.

Why People Become Vulnerable to Trafficking

People are not trafficked because they are weak. They are trafficked because exploiters target situations where protection is missing. Vulnerability can be caused by poverty, conflict, family breakdown, homelessness, discrimination, unsafe migration, lack of documents, addiction, disability, debt, climate pressure, care experience, gender-based violence or online isolation.

UNODC’s 2024 reporting warned that poverty, conflict and climate leave more people vulnerable to trafficking, with child trafficking, forced labor and forced criminality rising among detected cases.

Why Not For Sale Uses a Prevention Lens

Not For Sale’s work is built around the idea that trafficking prevention must begin before exploitation takes hold. Prosecution matters. Rescue matters. Survivor support matters. But if the systems that create vulnerability remain unchanged, traffickers continue to find new people to exploit.

That is why prevention includes education, safe housing, legal identity, stable income, social innovation, survivor support, community protection and environmental restoration. In Thailand, for example, Not For Sale supports safe housing, education and outreach for children at extreme risk near the Thai-Myanmar border, including stateless children who may otherwise be locked out of education and formal protection.

FAQ

What is human trafficking in simple terms?

Human trafficking is exploiting a person for labor, services, commercial sex or other purposes through control, coercion, deception or abuse of vulnerability. It is not defined only by movement. A person can be trafficked without crossing a border.

What are the three elements of human trafficking?

For adults, the three elements are an act, a means and a purpose. The act may be recruitment or harboring. The means may be force, fraud or coercion. The purpose is exploitation. For children, the means element is not required.

Is human trafficking the same as modern slavery?

No. Human trafficking is one form of modern slavery, but modern slavery is broader. It also includes forced labor, forced marriage, slavery, servitude and slavery-like practices.

Is trafficking always international?

No. Trafficking can happen within one country, one city, one neighborhood, one workplace or one home. Border crossing is not required.

What is the difference between trafficking and smuggling?

Smuggling is usually about facilitating illegal border entry for payment. Trafficking is about exploitation and control. Smuggling can become trafficking if a person is later exploited through debt, threats, coercion or abuse of vulnerability.

What is forced labor?

Forced labor is work or service performed under threat of penalty and without genuine voluntary consent. It can involve threats, debt, violence, withheld wages, document confiscation, isolation or immigration pressure.

What is sex trafficking?

Sex trafficking is commercial sexual exploitation involving force, fraud or coercion. If the person involved is under 18, it is trafficking even without proof of force, fraud or coercion.

What is child trafficking?

Child trafficking is the recruitment, movement, harboring or receipt of a child for exploitation. A child is anyone under 18. Unlike adult trafficking, the means of coercion does not need to be proven.

What are the signs of human trafficking?

Possible signs include fear, control by another person, lack of documents, unpaid wages, debt, restricted movement, isolation, injuries, excessive working hours, being unable to speak freely, or being underage in commercial sex. Indicators do not prove trafficking alone, but they should prompt concern.

Why is online trafficking increasing?

Online spaces allow traffickers to recruit, groom, advertise, threaten and monitor victims at scale. Digital tools can also be used in forced fraud, sextortion, scam compounds and online sexual exploitation.

How does ecocide connect to human trafficking?

Ecocide can destroy livelihoods, displace communities and expand illegal economies. When people lose land, income, safety or legal options, traffickers can exploit that vulnerability through forced labor, mining, logging, agriculture, sexual exploitation or unsafe migration.

What can readers do?

Readers can learn accurate definitions, share verified information, support survivor-centered organizations, ask businesses about forced labor risks, recognize warning signs, avoid sensational language and support prevention models that address root causes before exploitation begins.
