Released/updated on: 2025-09-10
Geographic coverage: United States
Time period: 2015-01-01--2020-01-01

The National Institute of Justice funded the Urban Institute to conduct this multi-site, mixed-methods evaluation of the impact of the U.S. DOJ-funded Enhanced Collaborative Model (ECM) task forces on addressing human trafficking. Specifically, this study sought to (1) understand the impact of the ECM task forces in identifying and assisting human trafficking survivors and investigating and prosecuting human trafficking, and (2) analyze differences in various task force implementation models (e.g., structure and organization) to understand which task force models and features contribute to prosecutions. In addition, this research sought to understand the investigative, prosecutorial, and victim services practices among ECM task forces; challenges and barriers task forces face in combating human trafficking; and synthesize best practices and recommendations for developing and implementing successful task forces.

This data collection includes three datasets compiled from law enforcement closed case files and organized for analysis by case, victim(s), and suspect(s). The collection also includes a README file describing qualitative data consisting of transcripts from interviews with law enforcement officers and other stakeholders involved with ECM task forces.

Released/updated on: 2019-10-29
Geographic coverage: United States
Time period: 1998-01-01--2005-01-01

To increase understanding of the prosecution of Commercial Sexual Exploitation of Children and Youth (CSEC) offenders, the Urban Institute, a non-partisan social and economic policy research organization, along with Polaris Project, an anti-human trafficking organization based in the United States and Japan, were awarded a cooperative agreement from the Office of Juvenile Justice and Delinquency Prevention (OJJDP) to conduct a 12-month study on CSEC in the United States. The purpose of this research was to conduct a national analysis of federal prosecutions of CSEC-related cases from 1998 through 2005, in order to answer the following four research questions:

  • Is the United States enforcing existing federal laws related to CSEC?
  • What are key features of successfully prosecuted CSEC cases? What factors predict convictions in cases? What factors predict sentence length?
  • Have the U.S. courts increased penalties associated with sexual crimes against children?
  • What, if any, are the effects of CSEC legislation on service providers who work with these victims?
  • The data collection includes three datasets: (Dataset 1) Base Cohort File with 7,696 cases for 50 variables, (Dataset 2) Commercial Sexual Exploitation of Children (CSEC) Defendants in cases filed in U.S. Court with 7,696 cases for 100 variables, and (Dataset 3) Suspects in Criminal Matters Investigated and Concluded by U.S. Attorneys Dataset with 13,819 cases for 14 variables.
