The Bureau of Justice Statistics (BJS) initiated a multiyear effort to improve the efficiency, reliability, and utility of the National Crime Victimization Survey (NCVS). The effort had three main goals: modernize the organization and content of the NCVS instrument, increase the quality of information collected and efficiency of the instrument flow, and improve the measurement and classification of crime. To that end, BJS is redesigning the entire survey instrument, which includes a household roster, a victimization screener, and a detailed crime incident report (CIR). Each of these instrument components were examined in the NCVS Instrument Redesign Field Test. This large-scale national field test was conducted from October 2019 to March 2020 to compare the performance of the current NCVS instrument and procedures (Condition 1) against the redesigned instrument (Condition 2). For more details on this effort, see the NCVS Instrument Redesign webpage.

After the large-scale field test, a smaller test was conducted that assessed the feasibility of conducting the NCVS as a self-administered, web-based instrument. This test included two samples: an address based sample (Condition 3A) and a sample of individuals who were part of an existing web-based panel (Condition 3B).

This study investigated the complex relationship between unauthorized immigration and crime at the local level. Through a mix of data fusion, synthetic population modeling, and detailed crime reporting from selected jurisdictions, the study sought to produce nuanced insights to challenge prevailing assumptions about immigration and crime, ultimately aiding in informed policy-making and resource allocation.

This study employed crime and crime reporting data from ten jurisdictions across the United States paired with synthetic data which estimated the unauthorized immigrant population. This research aimed to provide an in-depth analysis at the census tract level. Analyses focused on unauthorized immigration and its correlation with drug, property, and violent crime rates, while accounting for crime reporting in traditional and emerging immigrant destinations along with sites with low foreign populations.

This dataset measures the number and density of law enforcement organizations—including police departments, fire departments, courts, correctional facilities, and legal counsel and prosecution offices—across United States census tracts and ZIP Code Tabulation Areas (ZCTAs) from 1990 through 2022. Data are derived from the National Establishment Time Series (NETS) database and geocoded to 2010 and 2020 TIGER/Line shapefiles from the US Census Bureau.

This data collection is part of the Monitoring the Future series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth in eighth, tenth, and twelfth grades. The restricted data sets in this collection include variables that were altered or omitted from the public use data sets to maintain respondent confidentiality. Examples of variables included in their original form are: unaltered sampling weight variable, variables for strata and cluster to account for the complex sample design of the MTF, and previously-omitted data on some variables for the Western region of the US. For each year from 1976 through 2017, two data sets containing data for all three grades are available: one dataset including school-level state, county, and Zip Code variables, and one dataset without these geographic school-level variables. For 2018-2022, data sets were created separately for 8th/10th and 12th grades, resulting in four data sets. This split on grade was done to mirror the data availability of the public use files and facilitate the merging of the public and restricted use data. For 2023 forward, only two data sets are provided: one for the 8th and 10th grades, and one for the 12th grade. Please note: Use of the geographic identifiers such as state, county, or zip code is limited and researchers interested in these variables are encouraged to read FAQs: About MTF Restricted-Use Geographic Variables.

Also included as part of each annual collection is a zip archive of the Monitoring the Future public-use data and documentation for each respective year. The basic research design used by the Monitoring the Future study involves annual data collections from eighth, tenth, and twelfth graders throughout the contiguous United States during the spring of each year. The 8th/10th grade surveys consist of four different questionnaire forms (two forms from 1991-1996), and the 12th grade surveys consist of six questionnaire forms (five forms from 1976-1988). Identical forms are used for both eighth and tenth grades, and for the most part, questionnaire content is drawn from the twelfth-grade questionnaires. Thus, key demographic variables and measures of substance use and related attitudes and beliefs are generally identical for all three grades. However, many fewer questions about lifestyles and values are included in the 8th/10th grade surveys. Substance use covered by these surveys includes tobacco, smokeless tobacco, alcohol, marijuana/cannabis, prescription medications, over-the-counter medications, inhalants, steroids, LSD and other hallucinogens, amphetamines (stimulants), sedatives/barbiturates, tranquilizers, cocaine, crack cocaine, ecstasy, methamphetamine, heroin, narcotics other than heroin, and vaping of nicotine, marijuana/cannabis, and flavors. Other topics include: attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime (both in and out of school).

The Detroit Metro Area Communities Study (DMACS) is a panel survey of Detroit residents aged 18 and older. The original panel of respondents was drawn from an address-based probability sample of all occupied Detroit households in 2016 and has since been refreshed through additional address-based sampling annually. Between August 6, 2025 and October 1, 2025, 3,170 previously enrolled panelists were invited to participate in a self-administered online or interviewer-administered telephone survey.

Topics included: household composition; housing status; perceptions of neighborhood; social connection and loneliness; election; mayoral priorities; crime and safety; violence reduction; artificial intelligence; flood management; mental health; employment.

The Nashville Longitudinal Study of Youth Safety and Wellbeing (NLSYSW) was created to provide multi-level, multi-sector, longitudinal data on key ecological and developmental factors that impact youth violence and school safety. The data collected for this study include longitudinal survey and administrative data on disciplinary referrals and sanctions, social emotional competencies, school climate, community violence exposure, and attitudes toward violence from students in grades kindergarten through 12 in the Metropolitan Nashville Public Schools (MNPS) school district. In addition, this collection includes measures of several ecological influences, including school environment (e.g., programs/interventions offered, climate, and school safety) and neighborhood context (e.g., neighborhood economic structure, assets and resources, crime, gun violence, and housing) that can be linked to student data via neighborhood. The data provided spans the period of 2009 through 2022, with most intense coverage of 2018 through 2021.

These data have been utilized by an interdisciplinary team of researchers, educators, city government officials, police, juvenile courts, and youth development workers to support school and community initiatives related to understanding a) the role of neighborhood exposure to violence and disadvantage on students' norms/attitudes, behaviors, and achievement, b) the role of school climate and access to resources in moderating neighborhood and student risk factors, c) the neighborhood, school, and individual factors that influence students' social and emotional competence, and d) the neighborhood, school, and student factors that affect racial/ethnic disparities in office disciplinary referrals and the use of exclusionary discipline.

Demographic information at the student-level includes grade, gender, and race/ethnicity. At the school building-level, White, Black, and Hispanic staff percentages are provided.

The Detroit Metro Area Communities Study (DMACS) is a panel survey of Detroit residents aged 18 and older. The original panel of respondents was drawn from an address-based probability sample of all occupied Detroit households in 2016 and has since been refreshed through additional address-based sampling annually. Between June 18, 2024 and August 19, 2024, we invited 3,012 previously enrolled panelists 4,000 invitations to a randomly selected address-based refreshment sample of Detroit households to participate in a self-administered online or interviewer-administered telephone survey.

Topics include: housing status; perceptions of neighborhood; neighborhood blight; social connection; election; crime and safety; municipal services; mental health; employment.

The Cuyahoga County (Ohio, USA) Sexual Assault Kit (SAK) Initiative, led by the Cuyahoga County Prosecutor's Office, was launched in 2013 to test and follow up on previously untested sexual assault/rape kits that were collected as evidence from sexual assault victims. Rape reports typically include an incident report taken by the responding officer(s) who is tasked with gathering pertinent facts and evidence and then forwarding the report to an investigator (detective) for follow-up, as well as a summary of the investigative activity on the case as noted by the investigator, which can include the decision of the assigned prosecutor to file or not file charges.

Signaling is defined as information conveyed by responding officers in the narratives of police reports regarding a victim's creditability and rape-myth adherence. The goal was to better understand if and how responding officers' written reports in sexual assault cases impact investigating officers' decision-making and how cases proceed (or fail to proceed) in the criminal justice process. The objective of the study was to explore the first step in the investigative process to elucidate facilitators and barriers to sexual assault cases reaching a successful disposition.

The research team employed text mining and machine learning methods using natural language processing and advanced statistical analyses to evaluate the narratives of 5,638 police reports of sexual assaults where victims had sexual assault kits collected in Cuyahoga County over the span of nearly two decades (primarily 1993 through 2011). These reports were analyzed using topic modeling and sentiment analysis. The team addressed three research questions:

1. To what extent did "sentiments" in the responding officers' narratives reveal positive or negative signaling of victims' credibility?
2. To what extent were the "topics" and sentiments in the responding officers' narratives different in cases with increased investigative activity compared to those with less?
3. To what extent were both the topics and sentiments in the responding officers' narratives different for cases that were successfully investigated and prosecuted compared to those that were not?

This collection includes a quantitative dataset (DS1) and a qualitative dataset (DS2). The report-level quantitative dataset contains calculated sentiment scores, categorical variables describing the incident and outcome, and demographic variables of the victim(s) and suspect(s) for all reports analyzed (n=5,639). The full text for all reports is available in a CSV file that can be merged with the main data file. The qualitative data is a subset of reports from the main dataset (n=18) with high, medium, and low sentiment scores that were manually coded by the research team.

This study collected and combined data from a large number of sources (e.g. crime data, land use data, parolee data, business and employment data, etc.) to study crime and crime trends across two counties in Southern California: Los Angeles and Orange counties. The crime data comes from a number of police agencies for the years 2005-12. Crime data is not available for all cities for all years. The variables from other sources are for the year 2010. All data is aggregated to the common geographic unit of census tracts. The data come from the following sources: 1) crime data from police agencies; 2) socio-demographic data from the American Community Survey (ACS) obtained from ICPSR; 3) business data from Mint data; 4) land use data from the Southern California Association of Governments; 5) voluntary organization data from the National Center for Charitable Statistics.

This wide array of information allows accounting for the multi-dimensional and inter-related sources of crime and crime trends in Southern California in neighborhoods (census tracts). Using these data, the project: 1) built a model to predict crime in small geographic areas; 2) assessed the effect of neighborhood organizations and institutions on crime rates; 3) determined the effect of the spatial distribution of poverty (at both small and large scales) on crime rates; 4) assessed how the clustering of social problems in a neighborhood affects neighborhood crime over time. This project built on prior work done by the Metropolitan Futures Initiative (MFI) team to locate various data sources in Southern California.

This study explored the life-course experiences of criminally involved veterans. The topics of maladaptive behavior patterns, criminal conduct, diverging demographic and social statuses, impacts of mental illness, social support, substance use, propensity for criminal involvement before entering the military, and combat exposure, of the veterans were explored. The project aimed to uncover common links to problematic life-course outcomes thematically shared across cohorts of criminally involved veterans and/or differences between cohorts of veterans resulting in unique needs across the life-course.

This study included three aims of analysis:

1. To explore the life-course experiences of veterans who are in the criminal justice system by assessing the perspectives of this particularly important group - those under the control of the criminal justice system, but also navigating their problems while living in the community.
2. To document the ecological momentary day-to-day experience of these individuals, in order to better understand how experience shapes normative daily behavior, mood fluctuation, self-esteem, and psychological well-being.
3. To explore the relationships of these individuals tapping into the perspectives of family/social networks members who are closest to the criminally involved veterans to better understand how deviance impacts family and social support systems - in addition to considering the complex dynamics of these relationships.

Users should note that this study included interviews, provided in qualitative transcripts. The associated qualitative data is currently not included in this release, but will be provided at a later date.

UPDATE NOVEMBER 2025: There is an issue with merging the restricted-use and public-use data files for the 8th/10th grades. The current 8th/10th grade public-use data file [study 38883, DS1] has incorrect Archive IDs (AI_08 and AI_10). To fix the IDs so the merge of public- and restricted-use data is correct, please see Dataset 6 (DS6) in this study. Documentation is provided about the issue and a dataset is provided to fix the ID mis-match. Note that all survey data are correct - the problem is only with the archive ID variables.

This survey of 12th-grade students is part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students are randomly assigned to complete one of six questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and substance use. There are about 1,400 variables across the six questionnaires. Substance use covered by these surveys includes tobacco, smokeless tobacco, alcohol, marijuana/cannabis, prescription medications, over-the-counter medications, inhalants, steroids, LSD and other hallucinogens, amphetamines (stimulants), sedatives/barbiturates, tranquilizers, cocaine, crack cocaine, ecstasy, methamphetamine, heroin, narcotics other than heroin, and vaping of nicotine, marijuana/cannabis, and flavors. Other topics include attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime (both in and out of school).

Highlights for 2024:

• The MTF sampling procedure was updated in 2024. Please see the 2024 MTF annual report for details. Variable-specific details are found in the user's guide that accompanies this study.
• Continuation of randomized blocks of questions presented to students. Please see Appendix D of the user's guide.
• In 2023, the question about use of Delta-8 THC was included only on forms 3 and 6. In 2024, this question is now included on all survey forms. With the inclusion on all forms, please note these variable name changes:
  • CORE: V2934 was changed to V7976
  • Form 3: V3660 was changed to V7976
  • Form 6: V6676 was changed to V7976
• Changes were made to the question stems for many of the substance use "triplets", i.e. lifetime, 12 month, and 30 day timeframes, including: marijuana/cannabis, hallucinogens other than LSD, amphetamines (stimulants), sedatives/barbiturates, tranquilizers, and narcotics other than heroin.
• Additional information about question text and response option changes, along with details about added and dropped questions, are documented in the MTFQchanges2024byForm.pdf and MTFQchanges2024byType.pdf files available for download.
• MTF is no longer providing dichotomized substance use variables on the DS1 datasets. As each researcher has their own method of working with data, it is up to the researcher to create these variables for their specific needs.

This study looks at the impact of police departments' organizational and managerial characteristics on police-community relations. Particular attention is paid to communities of color in the analysis. The dataset merges variables from various data sources. These include the following series housed within ICPSR:

• Two sub-series within the The Uniform Crime Reporting Program Data Series: Law Enforcement Officers Killed and Assaulted (LEOKA), and Offenses Known and Clearances by Arrest
• The Law Enforcement Management and Administrative Statistics (LEMAS) Series

Additionally, the following sources are also contained in the final dataset and available online:

• The Fatal Encounters and Police Violence Project, both of which track the number of people killed by police.
• The American Community Survey, which is conducted by the U.S. Census Bureau.

Variables include officer counts, demographics, weapons used, technologies, duties performed, salary figures, department units, qualifications, training structure, budgets, states, and addresses by department. Total crimes for each jurisdiction are collected. The presence of officer foot patrols, civilian review boards, and other community policing initiatives are measured. Violence committed against officers and civilians are included. Demographic variables of residents of jurisdictions including poverty, housing status, race, marital status are collected as well.

In 2024, the NCVS instrument was redesigned. The data in this study were collected from the legacy instrument. Please see the Collection Notes below for more details.

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. 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 dataset represents the concatenated version of the NCVS on a collection year basis for 1992-2024. 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 39272.

The COVID-19 pandemic has resulted in the scapegoating of Asians, leading to a rise in hate crimes against them and adversely affecting their mental health and well-being. This project seeks to visualize the connection between structural racism, health, and anti-Asian Hate Crime (AHC) incidents reported in both the Federal Bureau of Investigation (FBI) and news and social media collected by the the Asian American Foundation (TAAF) during the period of 2020-2021. The project will first visualize the pattern of AHC incidents reported in FBI and media data, considering variations by states, counties, and months. This project will then identify state- or county-factors associated with AHC incidents and visualize them. The project will further examine changes in mental health and coping behaviors, following AHC incidents. The project will finally explore whether community-level AAPI organizations availability can mitigate the adverse effects of AHC incidents on mental health and coping behaviors.

The project's target audience includes social change networks, media outlets, academic society, federal/state legislators, and national-level professional organizations. The resulting visualizations will facilitate policy debates surrounding various aspects, such as addressing underlying risk factors related to AHC, improving data collection and reporting methods within law enforcement agencies to accurately document AHC incidences in Federal/State archives, implementing policies and interventions to mitigate adverse effects on people's health, promoting understanding of cultural differences and inclusivity.

This project examined the multidimensional pathways that led to extremism and extremist behaviors. The focus of the research was to examine risk and protective factors that either directly, or in combination, interact to increase or mitigate the risk of radicalization and terrorism.

This project comparatively examined the presence/absence of risk and protective factors across three groups:

1. extremist individuals who committed ideologically motivated violent (fatal and non-fatal violent attacks) and nonviolent (financial) crimes
2. extremists who did not break the law and only engaged in legal extremist activities
3. persons who committed non-ideological motivated homicides and other violent attacks

Thus, researchers accomplished four major goals/objectives in this project. First, although there has been a good amount of radicalization and risk assessment-related research on risk and protective factors, researchers expanded this work with comparative analyses that have not been previously explored. Second, few studies compared violent or nonviolent criminal extremists to nonoffending extremists or other types of violent offenders. Third, researchers used a case-control approach to provide an empirically robust understanding of categorical differences across groups that have not yet been achieved. Fourth, researchers examined differences in participation of warning behaviors across the groups studied.

The data file includes 971 cases.

The effective treatment of youth with co-occurring mental health and substance use disorders placed in juvenile justice residential facilities aims to effect positive change among youth in the system's care and promote public safety. This study aimed to examine the prevalence of co-occurring disorders among a multiyear, statewide sample of youth completing residential placement within the juvenile justice system in the state of Florida.

• Determine the prevalence of mental health and substance use disorders, and their co-occurrence among youth placed in long-term juvenile justice facilities across the state of Florida
• Assess the impact of service matching to assessed dynamic risk factors, dosage of intervention services actually provided to each youth, and treatment quality/fidelity of those interventions on both changes in risk and protective factors during placement and post-release recidivism outcomes
• provide policy recommendations related to the efficacy of best practices through the combination of service matching/dosage/treatment quality of treatment within residential facilities among youth presenting with co-occurring disorders

This project was an experimental evaluation of a collaborative partnership among the Center for Evidence-Based Crime Policy at George Mason University (CEBCP-GMU), Roanoke Police Department (RPD), Roanoke County Police Department (RCPD), Salem Police Department (SPD), and Vinton Police Department (VPD) as well as Blue Ridge Behavioral Healthcare (BRBH) in Roanoke Valley region of Virginia to conduct a place-based cluster randomized controlled trial (RCT) to evaluate the effects of the co-responder model on subsequent outcomes of individuals who were experiencing a crisis and involved in mental health-related calls for service. Responding to incidents involving individuals with mental illness has been a challenge for police officers.

While co-response teams have been embraced as an effective police response strategy, most prior evaluation studies on co-response teams focused on outcomes that are not directly related to individuals' subsequent mental health state. Additionally, the lack of experimental research hinders our ability to draw causal conclusions on the effects of co-response teams. To address this knowledge gap, this study evaluated the effectiveness of co-response teams on hospitalization outcomes of individuals in crisis using a place-based randomized controlled trial in southwest Virginia.

In order to investigate whether reductions to sentence length reduce recidivism and its related costs, the research team conducted two studies under the same NIJ grant.

In Study 1, the research team used a quasi-experimental approach to examine how sentence length influenced time to rearrest. Specifically, the team estimated an instrumental variable hazard model using variation stemming from the implementation of South Dakota's Public Safety Improvement Act of 2013 (SB70). SB70 was a major sentencing reform that reduced the likelihood of incarceration and the length of sentence for certain non-violent offenses. The legislation was a response to high rates of incarceration and rising criminal justice costs with a particular focus on addressing individuals convicted of non-violent offenses. The goal was to improve public safety while reducing corrections spending. For grand theft below $5,000 and third-degree burglary, the reform reduced the severity of the felony class and the maximum allowed sentence length by 50% to 80%. Only certain offenses were subject to sentencing reductions such that unaffected offense types were included in the analysis as a comparison group.

In Study 2, the research team applied the logic of recurring event hazard models that predicted the probability of events over time with two distinct objectives: to identify desisters and to estimate the impact of life events on the longitudinal pattern of offending. Administrative data from the North Carolina Department of Public Safety (NCDPS) Division of Adult Correction were obtained to answer this research question. The team connected commonly used trajectory models to recurrent event survival models.

This collection contains only syntax files and documentation that were created for Study 1 (South Dakota).
