This study extended the understanding of human trafficking among youth involved in child welfare and juvenile justice systems by examining relationships among trafficking victimization, youth characteristics, and experiences in the juvenile justice, child welfare, and criminal justice systems. Using de-identified linked administrative data provided by the Florida Department of Juvenile Justice (DJJ), Florida Department of Law Enforcement (FDLE), and the Florida Department of Children and Families (DCF), researchers:

1. informed identification of trafficking victimization by assessing the predictive utility of Florida's Human Trafficking Screening Tool, using ordered multinomial regressions and factor analysis;
2. informed response to trafficked youth by describing characteristics of those who experience trafficking during juvenile justice or child welfare supervision, or who enter juvenile justice supervision with prior human trafficking allegations, using descriptive statistics and linear and logistic regression;
3. informed secondary prevention for at-risk youth by identifying those at greatest risk of human trafficking throughout adolescence, and informed tertiary prevention among trafficked youth by identifying those at greatest risk of subsequent victimization following an initial trafficking allegation;
4. investigated the longitudinal association between human trafficking allegations and subsequent juvenile and adult criminal charges. Data collection included all youth served by DCF who were born in or after 1993, and whose records included at least one maltreatment allegation before February 29th, 2020.

The National Crime Victimization Survey (NCVS) Series, previously called the National Crime Surveys (NCS), has been collecting data on personal and household victimization through an ongoing survey of a nationally-representative sample of residential addresses since 1973. The NCVS was designed with four primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the number and types of crimes not reported to the police, (3) to provide uniform measures of selected types of crimes, and (4) to permit comparisons over time and types of areas. The survey categorizes crimes as "personal" or "property." Personal crimes include rape and sexual attack, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes include burglary, theft, motor vehicle theft, and vandalism. Each respondent is asked a series of screen questions designed to determine whether she or he was victimized during the six-month period preceding the first day of the month of the interview. A "household respondent" is also asked to report on crimes against the household as a whole (e.g., burglary, motor vehicle theft). The data include type of crime, month, time, and location of the crime, relationship between victim and offender, characteristics of the offender, self-protective actions taken by the victim during the incident and results of those actions, consequences of the victimization, type of property lost, whether the crime was reported to police and reasons for reporting or not reporting, and offender use of weapons, drugs, and alcohol. Basic demographic information such as age, race, gender, and income is also collected, to enable analysis of crime by various subpopulations. This version of the NCVS, referred to as the collection year, contains records from interviews conducted in the 12 months of the given year.

Statutory rape laws vary widely between U.S. states, making the measurement of its incidence in the broader U.S. population either impossible within contemporary datasets or too painstaking for researchers to pursue without support. To address this issue, this study examined the prevalence, characteristics, and consequences of statutory rape victimization and perpetration in the United States using the National Longitudinal Survey of Youth 1997 (NLSY97), the National Incident-Based Reporting System (NIBRS), and the U.S. Census Bureau's American Communities Survey (ACS). To establish an empirical foundation for the study of statutory rape, this study pursued the following key objectives:

1. • Estimate nationally representative rates of statutory rape victimization and perpetration in the United States using the NLSY97, focusing on a) age-graded rates of victimization, b) age-graded rates of perpetration, and c) risk factors for statutory rape victimization and perpetration.
   • Assess situational differences between first sexual experiences that are statutory rape compared to those that are not, and assess the effectiveness of statutory rape laws across states with lax, moderate, and strict laws to affect teen sexual activity and victimization rates.
   • Estimate the likelihood of women's statutory rape victimization being reported to police, using NIBRS data on women's victimization and men's perpetration.
   • Assess the short and long-term consequences of statutory rape victimization based on a) the nature and characteristics of relationships between victims and perpetrators and b) the age difference between victims and perpetrators.

This collection includes the syntax files and data-map documentation needed to reproduce the data analysis conducted by this project, along with information describing the processes used to access NLSY97, NIBRS, and ACS data. Users should refer to the ICPSR README file for an inventory of all syntax and data-map files.

The National Survey of Youth in Custody (NSYC) is part of the BJS National Prison Rape Statistics Program to gather mandated data on the incidence of prevalence of sexual assault in juvenile facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108-79). The Act requires a 10 percent sample of juvenile facilities to be listed by incidence of sexual assault. Data are collected directly from youth in a private setting using audio computer-assisted self-interview (ACASI) technology with a touch-screen laptop and an audio feed to maximize inmate confidentiality and minimize literacy issues. The NSYC-3 was administered to 6,910 youth in 332 state operated and locally or privately operated juvenile facilities within the United States. Youth were randomly assigned to either a sexual victimization questionnaire (90%) or an alternative questionnaire (10%).

Sexual victimization questionnaire: Youth selected for this questionnaire received one of two versions, based on their age. The Older Youth questionnaire was administered to youths ages 15 and up, and the Younger Youth questionnaire was administered to those 14 and younger. The survey was divided into six sections. Section A collected background information, such as details of admission to facility and demographics including education, height, weight, race, ethnicity, gender, sexual orientation, and history of any forced sexual contact. Section B, Facility Perceptions and Victimization, included respondents' opinions of the facility and staff, any incidence of gang activity, and any injuries that had occurred. Section C, Sexual Activity Within Facility, captured the types of sexual contact that occurred and the circumstances of sexual contact. Section D, Description of Event(s) with Youth, and Section E, Description of Event(s) with Staff, focused on when and where the contact occurred, the race and gender of the other youths or staff members, if threats or coercion were involved, and outcomes, including whether or not the sexual contact was reported. Section F collected additional information about the youth, such as disability and mental health conditions, and the facility, including living conditions and use of restrictive housing.

Alternative questionnaire: A random selection of youth were assigned to an alternative questionnaire to "mask" which questions an individual might have been asked. In addition to Sections A, B, and F from the sexual victimization questionnaire, this questionnaire included sections on facility living conditions, mental health, grievance procedures, substance use, treatment programs, living arrangements, youth education and aspirations, communication with family, and post-release plans.

A Facility Questionnaire (FQ) collected in-depth information on each sampled facility via an online questionnaire. Topics included number of facility staff by race/ethnicity, job category, age, and length of service; staff turnover/vacant positions; personnel screening; staff training; number of youth, admissions, and discharges; rated capacity (i.e., number of beds), occupancy, and crowding; youth disabilities; grievance process; special housing; and youth education on PREA.

Other variables in the datasets include debriefing questions about respondents' experiences completing the survey, interviewer observations, created variables to summarize victimization reports (due to the complex routing in Section C), weight and stratification data, and administrative data about the facilities.

The National Inmate Survey, 2011-2012 (NIS-3) was conducted in 233 state and federal prisons between February 2011 and May 2012; 358 jails between February 2011 and May 2012; and 15 special (military, Indian country, and Immigration and Customs Enforcement (ICE)) facilities between February 2011 and May 2012. The data were collected by RTI International under a cooperative agreement with the Bureau of Justice Statistics (BJS). The NIS-3 comprised two questionnaires -- a survey of sexual victimization and a survey of mental and physical health, past drug and alcohol use, and treatment for substance abuse. Inmates were randomly assigned to receive one of the questionnaires so that at the time of the interview the content of the survey remained unknown to facility staff and the interviewers. A total of 81,566 inmates participated in the survey, including 32,029 inmates in state and federal prisons, 48,066 inmates in jails, 399 inmates in military facilities, 115 inmates in Indian country jails, and 957 inmates in facilities operated by ICE.

The NIS-3 was specially designed to provide estimates of sexual victimization for inmates ages 16 to 17 held in adult facilities. Previous NIS collections excluded inmates age 17 or younger due to special human subject issues (related to consent and assent, as well as risk of trauma in the survey process) and statistical issues (related to clustering of youth and the need to oversample to ensure a representative sample). To address issues of consent and risk, the NIS-3 juvenile sample was restricted to inmates ages 16 to 17 (who represented an estimated 95 percent of the 1,790 juveniles held in prisons at year end 2011 and 97 percent of the 5,870 juveniles held in local jails at midyear 2011).

The respondents were asked about the type of sexual contact, the frequency, when it occurred, and where it occurred. The survey also sought information on any injuries received and the treatment obtained for those injuries. Other questions pertained to the reporting of sexual contact -- if it was reported, to whom it was reported, and any results from reporting sexual contact. Respondents were also asked for reasons why they had not reported the sexual contact if no report was made. Background and demographic information collected includes reasons for incarceration, sexual history, sexual orientation, marital status, gender, ethnicity, and physical characteristics such as height and weight. The NIS-3 collected data on the mental health problems of inmates for the first time in 2011-12. Inmates were asked whether they had been told by a mental health professional that they had a mental disorder or if because of a mental health problem they had stayed overnight in a hospital or other facility, used prescription medicine, or they had received counseling or treatment from a trained professional.

The purpose of the project was to (1) determine whether the combined dynamic (SOTIPS) and static risk assessment (Static-99R) tools better predicted sexual recidivism than either alone, and (2) determine whether the tools could be implemented successfully in more representative populations. Previous research has established a "status quo" for risk assessments.

This study was set within the context of the developing sexual offender risk prediction field, where investigators explored reliable and valid means to assess what have been termed "dynamic risk factors." Instruments that identify the specific psychological risk factors present in the individual offender ought to allow treatment for that individual to be tailored to these specific needs, thus increasing its effectiveness. Thus, instruments have been designed to:

• Assess psychological factors that are empirically related to sexual recidivism, thus creating a basis for selecting treatment targets
• Show robust incremental predictive validity relative to Static-99R or other measures of static risk factors
• Measure change in a way that is convincingly related to sexual recidivism
• Incorporate and point risk managers towards some of the factors identified in the desistance literature
• Improve the effectiveness of treatment in reducing sexual recidivism

Enrollment of sex offenders in the evaluation study began in April 2013. To be included, offenders needed to be Static-99R eligible (an adult male convicted of a contact or non-contact sex offense with an identifiable victim), mentally cognizant, released to community supervision, and at least 18 years old in January 2013 in Maricopa County and April 2013 in New York City.

The 2016 National Crime Victimization Survey (NCVS) violent and property crime estimates were significantly higher than 2015, but it was not possible to determine the degree to which the change in rates resulted from the sample redesign rather than real changes in U.S. victimization levels. Therefore, the Bureau of Justice Statistics (BJS) examined the 2015 and 2016 victimization rates separately for new and continuing sample counties in the 2016 Criminal Victimization bulletin.

The BJS requested that the U.S. Census Bureau create a 2016 revised file with outgoing county interviews from July-December 2015, continuing county interviews from January-June 2016, and all interviews (continuing and new counties) from July-December 2016. In other words, the outgoing 2015 cases replaced the new 2016 cases in the first half of 2016. The files in this study serve as a separate research file to allow data users to make comparisons between 2015, 2016, and 2017 NCVS estimates using a nationally representative sample. It provides a sample that still represents the entire country but does not have the inflated crime rates seen in the new counties in 2016.

The data include type of crime, month, time, and location of the crime, relationship between victim and offender, characteristics of the offender, self-protective actions taken by the victim during the incident and results of those actions, consequences of the victimization, type of property lost, whether the crime was reported to police and reasons for reporting or not reporting, and offender use of weapons, drugs, and alcohol. Basic demographic information such as age, race, gender, and income is also collected, to enable analysis of crime by various subpopulations.

This dataset represents the concatenated version of the NCVS on a collection year basis for 1992-2018. A collection year contains records from interviews conducted in the 12 months of the given year. Under the collection year format, victimizations are counted in the year the interview is conducted, regardless of the year when the crime incident occurred.

For additional information on the dataset, please see the documentation for the data from the most current year of the NCVS, ICPSR Study 37297.

The National Crime Victimization Survey (NCVS), previously called the National Crime Survey (NCS), has been collecting data on personal and household victimization through an ongoing survey of a nationally-representative sample of residential addresses since 1973. The NCVS was designed with four primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the number and types of crimes not reported to the police, (3) to provide uniform measures of selected types of crimes, and (4) to permit comparisons over time and types of areas. Beginning in 1992, the survey categorizes crimes as "personal" or "property." Personal crimes include rape and sexual assault, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes include burglary, theft, motor vehicle theft, and vandalism. Each respondent is asked a series of screen questions designed to determine whether she or he was victimized during the six-month period preceding the first day of the month of the interview.

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?

Serial sexual assault is a pervasive problem: court record recidivism rates show that 10-15% of convicted sex offenders re-assault within five years and self-report studies suggest that 63-78% of males who have committed sexual assaults have raped more than one individual. The current study documents the scope of repeat sexual offending through a previously-unexplored method of documenting serial perpetration: DNA evidence in sexual assault kits (SAKs). Ultimately, the testing of N = 7,287 previously untested SAKs revealed n = 1,270 unique and identifiable perpetrators. When combined with information from lifetime criminal history records, 39.7% (n = 504) of this subsample of unique and identifiable perpetrators were found to be serial sexual offenders who committed, on average, 3.27 sexual assaults.

This study was designed to examine how districts that experienced an incident of school employee sexual misconduct in 2014 defined, interpreted, and implemented key elements of Title IX before, during, and after an incident. The study used a qualitative case study design with a purposeful sample of five districts recruited from a database of 459 districts who experienced a case of school employee sexual misconduct in 2014. The study was conducted between January 2016 and September 2017.

Data collected included: 1) various district documents, 2) 41 interviews with primary actors (school employees and county officials directly involved in responding to the incident), 3) 10 focus groups with 51 secondary actors (school employees who were not directly involved with the incident but who might have been indirectly affected by it), and 4) offender, victim and district characteristics. Documents reviewed included written policies and protocols, training materials and handbooks for staff and students, case documents, and other guiding documents as applicable. In interviews and focus groups, participants were asked to discuss their knowledge of district policies and procedures, to describe the dissemination of and any changes to these policies and procedures, and to provide recommendations for improvement. To protect the confidentiality all district and participant identifying information is confidential and has been removed from any reporting.

This study represents the first comprehensive national assessment of law enforcement uses of and perspectives on sex offender registration and notification (SORN) systems. The two-year, mixed-method study featured collection and analysis of interview data from over two-dozen jurisdictions, and administration of a nationwide survey of law enforcement professionals. The study examined ways in which law enforcement leaders, uniformed staff, and civilian staff engaged in SORN-related duties perceive SORN's roles and functions, general effectiveness, and informational utility. Additionally, the study elicited law enforcement perspectives related to promising SORN and related sex offender management practices, perceived barriers and challenges to effectiveness, and policy reform priorities.

This study measures the size and structure of the underground commercial sex economy in eight major US cities: San Diego, Seattle, Dallas, Denver, Washington, DC, Kansas City, Atlanta, and Miami. The goals of this study were to derive a more rigorous estimate of the underground commercial sex economy (UCSE) in eight major US cities and to provide an understanding of the structure of this underground economy.

Researchers relied on a multi-method approach using both qualitative and quantitative data to estimate the size of UCSE including:

1. Collecting official data on crime related to the underground weapons and drugs economies
2. Conducting semi-structured interviews with convicted traffickers, pimps, child pornographers, and sex workers at the federal, state, and local levels
3. Conducting semi-structured interviews with local and federal police investigators and prosecutors to inform our analysis of the interrelationship across different types of underground commercial sex activity.

This study tested a model of individual, familial, and peer variables that additively and synergistically increased or decreased the risk for sexual and teen dating violence based on bullying experiences in early adolescence. The study surveyed 1,162 students from three cohorts in four Midwestern middle schools, who were then followed into three high schools. Five waves of surveys collected information about the level of violence in student homes with parents and siblings or with other children, physical abuse, sexual abuse, exposure to domestic violence, frequency of bullying, self-reported delinquency, and exposure to delinquent friends during the middle school years. Waves six and seven were collected during high school and sexual violence and teen dating violence measures were added to the surveys.
