Summary
Trafficking in persons (TIP), also known as human trafficking, occurs across the United States and around the world. Traffickers exploit vulnerable individuals for commercial sex and forced labor in a variety of legal and illegal industries. For over two decades, Congress has legislated to counter human trafficking in the United States. Through the Trafficking Victims Protection Act of 2000 (TVPA, Division A of P.L. 106-386) and its subsequent reauthorizations, related anti-trafficking legislation, and administrative initiatives, the federal role in countering trafficking continues to be centered on the core pillars of preventing trafficking, prosecuting perpetrators, and protecting victims.
In 2021, the White House issued a National Action Plan to Combat Human Trafficking, which outlined a variety of principles and associated priority actions to reinforce the three pillars of the nation's anti-trafficking efforts. Under the protection pillar, the plan delineates specific principles tailored to supporting trafficking victims. These involve identifying and engaging with victims in an equitable victim-centered, trauma-informed, and culturally competent manner; safeguarding victims from being inappropriately incarcerated, fined, or otherwise penalized for unlawful acts committed as a direct result of being trafficked; improving access to immigration benefits and options so foreign national victims can receive efficient and effective assistance; expanding and improving assistance to victims encountered by federal law enforcement agencies; seeking financial remedies for victims; and offering or connecting victims to social services (including physical and mental health care, shelters and safe housing, education, and employment, among other forms of assistance) to increase short- and long-term stability.
With respect to offering and connecting trafficking victims to social services, several federal departments have programs or administer grants that are designed to support and provide ongoing protection and services to trafficking victims. The Department of Justice (DOJ) and the Department of Health and Human Services (HHS) are the primary departments administering grants for trafficking victim assistance.
Data on victims served by providers receiving federal trafficking victim assistance grants indicate that there may be disparities in populations served; for instance, data on victims served by grantees from DOJ's and HHS's trafficking victim assistance programs indicate that more women than men are served, and more victims of sex trafficking than labor trafficking are served. Additionally, available data on victims served with federal victim assistance funding focus more on the quantity of victims served and less on the quality of the services delivered and the outcomes for victims receiving services. As such, as policymakers examine federal efforts to provide services for victims of trafficking, they may question whether this assistance is reaching victims equitably and effectively.
Trafficking in persons (TIP), also known as human trafficking, occurs across the United States and around the world. Traffickers exploit vulnerable individuals for commercial sex and forced labor in a variety of legal and illegal industries. Although some estimates exist, comprehensive data on the incidence of human trafficking within the United States are not available.1 Some metrics suggest that more foreign victims may be involved in labor trafficking than in sex trafficking, and that more U.S. citizen victims may be involved in sex trafficking than labor trafficking.2 In addition, the federal government prosecutes more individuals for sex trafficking than for labor trafficking offenses.3
For over two decades, Congress has been legislating to counter human trafficking in the United States. The Trafficking Victims Protection Act of 2000 (TVPA, Division A of P.L. 106-386) and its subsequent reauthorizations have contained elements aimed at preventing human trafficking, strengthening criminal laws relevant to investigating and prosecuting traffickers, and providing protections and services for victims. Most recently, Congress passed legislation, including the Trafficking Victims Prevention and Protection Reauthorization Act of 2022 (P.L. 117-348) and the Abolish Trafficking Reauthorization Act of 2022 (P.L. 117-347), intended to further enhance the federal government's anti-trafficking efforts. These acts contained provisions that amended and reauthorized activities under the purview of the TVPA—including grants to support services for victims in the United States.
This report provides a brief background on human trafficking and the federal government's role in countering it. It specifically discusses the federal role in providing protection and services for victims and outlines federal grant programs authorized under the TVPA that provide funding for victim assistance. The report also includes considerations for policymakers as they evaluate the current landscape of victim services grants. While recognizing that there are important nuances between the terms, this report uses the terms victim and survivor in reference to individuals who have been trafficked.4
Conceptualizing Human Trafficking
Human trafficking in the United States is broadly conceptualized in two categories: sex trafficking and labor trafficking. Federal statutes do not formally define human trafficking or trafficking in persons. Rather, the TVPA defines severe forms of trafficking in persons as
(A) sex trafficking in which a commercial sex act is induced by force, fraud, or coercion, or in which the person induced to perform such act has not attained 18 years of age; or
(B) the recruitment, harboring, transportation, provision or obtaining of a person for labor or services, through the use of force, fraud, or coercion for the purpose of subjection to involuntary servitude, peonage, debt bondage, or slavery.5
Under the TVPA, force, fraud, or coercion are necessary elements to establish trafficking of an adult victim, but are not necessary elements to establish sex trafficking of a victim under age 18. It is not necessary to prove that people have moved across jurisdictional boundaries to establish that human trafficking has occurred. The term human trafficking is often used interchangeably with human smuggling, but they are distinct. As the U.S. Department of Homeland Security (DHS) has noted, "[h]uman trafficking does not require crossing a border. Human trafficking victims have been exploited by their trafficker for commercial sex acts or labor. By contrast, human smugglers engage in the crime of bringing people into the United States, or unlawfully transporting and harboring people already in the United States, in deliberate evasion of immigration law. In some situations, human smuggling may result in human trafficking."6
Federal Role in Countering Human Trafficking
Through the TVPA, related anti-trafficking legislation, and administrative initiatives, the federal role in countering trafficking continues to be centered on the core themes of prevention, prosecution, and protection.7
Prevention. Efforts to prevent human trafficking are broad; they range from expanding community outreach and awareness training about vulnerable populations to reducing demand for sex and labor trafficking. Prevention activities may be conceptualized in three categories:
As these categories indicate, in addition to federal efforts to prevent exploitation before individuals are victimized, other efforts are aimed at identifying human trafficking victims in order to rescue and protect them from further exploitation. For instance, a number of federal agencies administer public awareness campaigns to help recognize the signs of trafficking, identify potential victims, and respond appropriately.9 These efforts intersect directly with activities to provide services and ongoing protection to support trafficking victims.
Prosecution. Most federal human trafficking cases are investigated by the Federal Bureau of Investigation (FBI) and U.S. Immigration and Customs Enforcement, Homeland Security Investigations (ICE HSI), who coordinate with other agencies as appropriate. The U.S. Attorneys prosecute these cases.10
Protection. Several departments have programs or administer grants that are designed to support and provide ongoing protection and services to trafficking victims. (The Department of Justice [DOJ] and the Department of Health and Human Services [HHS] are the primary departments administering grants for trafficking victim assistance.) Such assistance may include temporary housing, independent living skills, cultural orientation, transportation, job training, mental health counseling, and legal assistance. Some observers may view these protection activities as part of tertiary prevention.
The Federal Role in Protections for Victims
Since the enactment of the TVPA, there has been greater awareness of the nature of human trafficking and breadth of victims' needs. These needs vary by individual and may include food, shelter, and clothing; medical, mental health, financial, and legal services; education and job training; immigration protections; and others. An enhanced understanding of human trafficking and its impact on victims has engaged a range of entities—including law enforcement, service providers, schools, child welfare, workforce development, and various industry sectors—in countering trafficking and providing victim assistance. Nonetheless, some analysts and advocates have noted gaps remain in services for victims.11
In 2021, the White House issued a National Action Plan to Combat Human Trafficking, which outlined a variety of principles and associated priority actions to reinforce the three pillars of the nation's anti-trafficking efforts: prevention, prosecution, and protection. Under the protection pillar, the plan delineates specific principles tailored to supporting trafficking victims. These involve the following:
These principles reflect an evolution in understanding the specific needs of trafficking victims. In line with this recognition, DOJ and HHS announced the need to develop standards of care specific to trafficking victims.14 While DOJ's Office for Victims of Crime (OVC) has model standards of care for serving victims of crime generally,15 anti-trafficking experts have considered a need for standards specific for trafficking victim service providers. OVC awarded a cooperative agreement to Freedom Network USA to help develop these standards.16 Once they are developed, policymakers may examine the role these standards may play in federal agency victim assistance grant solicitations.
A major aspect of U.S. anti-trafficking efforts is victim assistance—providing immediate services when victims are identified and helping them recover from their victimization. The TVPA has been the chief legislative vehicle authorizing these grants. In addition to funding grants for victim services, the federal government provides other forms of support for trafficking victims, such as the coordination of victim assistance by federal law enforcement17 as well as immigration relief for certain noncitizen trafficking victims.18 This section highlights TVPA-authorized grants for victim services in the United States, administered by DOJ and HHS.
DOJ Grants for Trafficking Victim Services
Through the TVPA and its subsequent reauthorizations, Congress authorized DOJ to administer grants for trafficking victim services in the United States. Specifically, "the Attorney General may make grants to states, Indian tribes, units of local government, and nonprofit, nongovernmental victims' service organizations to develop, expand, or strengthen victim service programs for victims of human trafficking."19 Using this authority, DOJ, through the OVC, funds a range of victim service grant programs, including the following:20
OVC also supports a number of more nuanced trafficking victim services grants, such as a program focused on providing housing assistance for victims and one focused on serving minor victims of labor trafficking.23
Congress provides funding for trafficking victim services grants through annual appropriations. The Consolidated Appropriations Act, FY2023 (P.L. 117-328) provided $95.0 million to DOJ for trafficking victim services under the State and Local Law Enforcement Assistance account.24 Additional financial support for these grants comes from the Domestic Trafficking Victims' Fund.
Domestic Trafficking Victims' Fund The Justice for Victims of Trafficking Act of 2015 (JVTA; P.L. 114-22) established an additional $5,000 penalty assessment on anyone convicted of certain federal trafficking-related offenses including peonage, slavery, or trafficking in persons; sexual abuse; sexual exploitation and other child abuse; transportation for illegal sexual activity; and certain human smuggling offenses. These monies are deposited into the Domestic Trafficking Victims' Fund (established by the act). The fund is to be administered by the Attorney General, in consultation with the Secretary of HHS. Money from the fund may be used to support certain existing grant programs authorized by the TVPA or to enhance programming for victims of child pornography served under the Victims of Child Abuse Act. There is a prohibition on the use of monies from the fund for medical items or health care services. Instead, an amount equal to that collected by the special assessments is to be transferred into the fund from money appropriated for community health centers (but not less than $5 million or more than $30 million); these funds may be used for grants supporting medical items or health care or services for victims served under the previously referenced TVPA grant programs and for victims of child pornography. The fund was most recently reauthorized by the Abolish Trafficking Reauthorization Act of 2022 (P.L. 117-347). The act removed sunset provisions that had previously been attached to the fund. In FY2022, $1,552,525 in penalty assessments was deposited into the fund; in addition, $5 million was transferred into the fund from HHS, as is done each fiscal year.25 |
HHS Grants for Trafficking Victim Services
Through the TVPA, Congress directed HHS to "expand benefits and services to victims of severe forms of trafficking in persons in the United States."26 Under this directive, HHS's Office on Trafficking in Persons (OTIP) administers trafficking victim services grant programs for both domestic and foreign national victims of trafficking.
Victim Services: Certification for Noncitizen Trafficking Victims Because noncitizens are ineligible for certain public benefits, the TVPA established a certification process through which noncitizen victims of trafficking who are certified as such are eligible for certain benefits and services.29 (U.S. citizen and LPR trafficking victims are not required to be certified in order to be eligible for these benefits and services.) The HHS Secretary, after consultation with the Secretary of Homeland Security, is responsible for issuing certification letters to adult noncitizen victims of trafficking.30 Certification by HHS affirms that a victim (1) is willing to assist in every reasonable way in the investigation and prosecution of severe forms of trafficking in persons and (2) has made a bona fide application for a T-visa that has not been denied, or has been granted continued presence in the United States by the Secretary of Homeland Security to effectuate the prosecution of traffickers in persons.31 Certification allows these noncitizen trafficking victims access to services including housing, medical care, monetary assistance, employment, education, and programs providing multiple needs assistance.32 |
Like DOJ's victim services programs, Congress funds HHS's trafficking victim services grants through annual appropriations. Funding is allocated from HHS's Refugee and Entrant assistance account. The Consolidated Appropriations Act, FY2023 (P.L. 117-328) provided funding for activities authorized under a number of acts, including Section 235 of the William Wilberforce Trafficking Victims Protection Reauthorization Act of 2008 (TVPRA; P.L. 110-457) and the TVPA.33 Similar to the DOJ grants for victim services, additional funding for HHS trafficking victim services grants comes from the Domestic Trafficking Victims' Fund.
Data on victims served by providers receiving federal trafficking victim assistance grants indicates that there may be disparities in populations served; for instance, data on victims served by grantees from DOJ's and HHS's trafficking victim assistance programs indicates that more women than men are served, and more victims of sex trafficking than labor trafficking are served.34 Additionally, available data on victims served with federal victim assistance funding focus more on the quantity of victims served and less on the quality of services and outcomes for individuals receiving services. As such, as policymakers examine federal efforts to provide services for victims of trafficking, they may question whether this assistance is reaching victims equitably and effectively.
Human Trafficking Data: A Complicating Factor In evaluating services to human trafficking victims, or any subset of this population, a primary complicating factor is a lack of knowledge about the true prevalence of human trafficking. Better data on human trafficking could help researchers, advocates, policymakers, and others better evaluate how well services are reaching the target population. Although comprehensive data on human trafficking within the United States are not available, some estimates exist.35
These snapshots may not be mutually exclusive, though the true extent to which they overlap is unclear. For instance, individuals who report potential victimization to the National Human Trafficking Hotline may or may not also report this information directly to law enforcement, and their victimization may or may not also be captured by victim service providers or in any number of research studies. |
Comparing Services for Sex Trafficking and Labor Trafficking Victims
The United States prosecutes more cases of sex trafficking than labor trafficking. In line with these prosecutions, federally funded service providers assist more victims of sex trafficking than labor trafficking. The State Department's 2022 Trafficking in Persons Report indicated that of the victims served by DOJ's trafficking victim services grantees, 68% were sex trafficking victims, 23% were labor trafficking victims, 7% were victims of both sex and labor trafficking, and 9% were victims whose type of victimization was unknown.36 Similarly, researchers from the Urban Institute conducted an evaluation of 10 of DOJ's Enhanced Collaborative Model task forces (funded from 2015 to 2017) and found that 70% of individuals served by victim service providers were victims of sex trafficking, and 30% were victims of labor trafficking. The researchers also identified some potential barriers in serving labor trafficking victims. These include that law enforcement may be more likely to focus resources and efforts on identifying and prosecuting sex trafficking cases; law enforcement may not have the "proper infrastructure, expertise, or training to fully investigate labor trafficking"; and labor trafficking can be harder to identify.37 Researchers also note that additional barriers to serving labor trafficking victims—who are more often foreign nationals—include victims' and service providers' hesitancy to contact law enforcement for fear that doing so will punish the victim for coming forward by subjecting them to removal (deportation) if they do not have a lawful immigration status.38
The 2022 Trafficking in Persons Report noted that the United States had not made progress toward comprehensively addressing labor trafficking. It also noted that services for "boys and men, LGBTQI+ persons, survivors struggling with substance abuse issues, persons with limited English proficiency, and children aging out of services, as well as those who did not wish to participate in the criminal justice system, continued to be insufficient."39 Among its priority recommendations, the report urged an enhancement of efforts to identify labor trafficking victims and provide them with services.40 DOJ, under its authority to develop, expand, or strengthen services to trafficking victims, administers a grant program focused on minor victims of labor trafficking.41 In its oversight of the federal grants serving trafficking victims, Congress may examine the extent to which federal departments administering grants for victim services—namely DOJ and HHS—may be evolving their efforts to reach the labor trafficking victim population.
Evaluating Victim Assistance: Output vs. Outcome
When reporting metrics on trafficking victim assistance, analyses often include data such as the number of victim service organizations receiving grants, the range of services offered by these organizations, and the number of victims receiving support funded by these grants. These are outputs, or quantifiable data that can help track the provision of victim services. However, there are relatively few outcome measures or indices that can increase understanding of the effectiveness and impact of victim services. Some researchers have been developing tools to further this understanding, generally. For example, RTI International, an independent, nonprofit research institute, worked with the Justice Research and Statistics Association and the Georgia Statistical Analysis Center to develop a survey that victim service providers can use to collect information from individuals served regarding the quality and impact of the services rendered.42 This survey, the Outcomes for Human Trafficking Survivors (OHTS) Instrument, measures progress of clients receiving victim services in four areas: safety, well-being, connectedness, and self-sufficiency.43 Additionally, the Urban Institute is currently partnering with the nonpartisan and objective research organization NORC at the University of Chicago to evaluate the reliability and validity of the OHTS Instrument and evaluate selected victim service providers with the tool.44 Analysts and policymakers may examine how well this type of tool can evaluate outcomes of human trafficking victim services, including evaluating those providers that facilitate a broad range of services, such as mental health, job training, legal services, and housing assistance, and those that support a specialized service type, such as housing assistance. Congress may debate whether additional federal support for evaluating the OHTS Instrument and other tools helps not only evaluate the effectiveness of federal grants for trafficking victim services but also helps provide the most useful services for victims.

As outlined by the Department of Justice (DOJ), "[b]oth terms are important and have different implications when used in the context of victim advocacy and service provision. For example, the term 'victim' has legal implications within the criminal justice process and refers to an individual who has suffered harm as a result of criminal conduct. The laws that give individuals particular rights and legal standing within the criminal justice system use the term 'victim.' Federal law enforcement uses the term 'victim' in its professional capacity. 'Survivor' is a term used widely in service providing organizations to recognize the strength and courage it takes to overcome victimization."
