The National Inmate Survey (NIS) is part of the Bureau of Justice Statistics' (BJS) National Prison Rape Statistics Program, which gathers mandated data on the incidence and prevalence of sexual assault in correctional facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108- 79). Inmates are randomly assigned to receive either a survey of sexual victimization or a survey of mental and physical health, past drug and alcohol use, and treatment for substance abuse. The data in this study focuses solely upon substance use and treatment from the "alternative" version of the survey.

These 6,577 respondents contained in this file who completed the "alternative" survey are the same 6,577 alternative respondents from the study National Inmate Survey (NIS) - Jails: Full Survey Respondents, [United States], 2007-2009 (ICPSR 37011).

Inmates are randomly assigned to receive either a survey of sexual victimization or a survey of criminal history, facility climate, and mental health. About 90 percent of the respondents completed modules through the survey of sexual victimization while the other 10 percent completed modules through the alternative survey. However, the data in this study focuses primarily upon criminal history, facility climate, and mental health. No respondent answered questions about sexual victimization.

Inmates are randomly assigned to receive either a survey of sexual victimization or a survey of mental and physical health, past drug and alcohol use, and treatment for substance abuse. About 88 percent of the respondents completed modules through the survey of sexual victimization while the other 12 percent completed modules through the alternative survey. However, the data in this study focuses solely upon substance use and treatment. No respondent answered questions about sexual victimization.

Policing the Rainbow is a mixed-methods study utilizing qualitative interviews and a survey conducted through the AmeriSpeak Panel at NORC at the University of Chicago. The aim of Policing the Rainbow was to better understand the relationship between law enforcement and the LGBTQ community.

Across the country, child welfare and juvenile justice systems now recognize that youth involved in both systems (i.e., dual system youth) are a vulnerable population who go unrecognized because of challenges in information-sharing and cross-system collaboration. These challenges currently prevent the development of accurate estimations of the number of dual system youth nationally and limit understanding of best practices used by jurisdictions implementing integrated systems models. OJJDP funded this secondary analysis study to address this gap in knowledge.

All data used in the Dual System Youth Design Study were owned or accessed by various partners. No primary data collection occurred in the study. In addition, most of the data accessed by the study partners was confidential, de-identified data that required memorandums of agreement and/or court orders to access and use. Some sites have ongoing or standing agreements with the public agencies who own the data which allow access and use for specific projects. Because, most frequently, the data are owned by the public service agencies and include sensitive information the data are not available to be publicly archived. Instead, here a descriptive overview is provided of the data used and accessed by each study partner as well as contact information of a person at each site that will be able to share syntax and/or coding parameters for those who are considering to replicate the findings or methods.

Researchers interested in inquiring the data and syntax used in this project should refer to the study partners section of the downloadable study documentation. Data provider agency names along with the specific study data that were requested are listed in the documentation.

In the United States, a number of challenges prevent an accurate assessment of the prevalence of hate crimes in different areas of the country. These challenges create huge gaps in knowledge about hate crime--who is targeted, how, and in what areas--which in turn hinder appropriate policy efforts and allocation of resources to the prevention of hate crime. In the absence of high-quality hate crime data, online platforms may provide information that can contribute to a more accurate estimate of the risk of hate crimes in certain places and against certain groups of people. Data on social media posts that use hate speech or internet search terms related to hate against specific groups has the potential to enhance and facilitate timely understanding of what is happening offline, outside of traditional monitoring (e.g., police crime reports). This study assessed the utility of Twitter data to illuminate the prevalence of hate crimes in the United States with the goals of (i) addressing the lack of reliable knowledge about hate crime prevalence in the U.S. by (ii) identifying and analyzing online hate speech and (iii) examining the links between the online hate speech and offline hate crimes.

The project drew on four types of data: recorded hate crime data, social media data, census data, and data on hate crime risk factors. An ecological framework and Poisson regression models were adopted to study the explicit link between hate speech online and hate crimes offline. Risk terrain modeling (RTM) was used to further assess the ability to identify places at higher risk of hate crimes offline.
