The study integrated neighborhood-level data on robbery and burglary gathered from local police agencies across the United States, foreclosure data from RealtyTrac (a real estate information company), and a wide variety of social, economic, and demographic control variables from multiple sources. Using census tracts to approximate neighborhoods, the study regressed 2009 neighborhood robbery and burglary rates on foreclosure rates measured for 2007-2008 (a period during which foreclosure spiked dramatically in the nation), while accounting for 2007 robbery and burglary rates and other control variables that captured differences in social, economic, and demographic context across American neighborhoods and cities for this period. The analysis was based on more than 7,200 census tracts in over 60 large cities spread across 29 states. Core research questions were addressed with a series of multivariate multilevel and single-level regression models that accounted for the skewed nature of neighborhood crime patterns and the well-documented spatial dependence of crime.

The study contains one data file with 8,198 cases and 99 variables.

The current study sought to expand the current understanding of the psychometric characteristics of the collective efficacy scale at the individual level and the role of collective efficacy in promoting safe, healthy community conditions. A team of interviewers consisting of residents of the targeted neighborhoods were selected and trained to administer the field surveys (NIJ Neighborhoods Resident Survey Data, 108 variables, n=649). In order to ensure accuracy of the responses, the field supervisor conducted telephone validation for approximately ten to fifteen percent of the surveys. In addition to resident surveys, trained research staff conducted systematic social observations (SSOs) of street segments in selected neighborhoods noting physical and social indictors.

The study includes data collected with the purpose of creating an integrated dataset that would allow researchers to address significant, policy-relevant gaps in the literature--those that are best answered with cross-jurisdictional data representing a wide array of economic and social factors. The research addressed five research questions:

1. What is the impact of gentrification and suburban diversification on crime within and across jurisdictional boundaries?
2. How does crime cluster along and around transportation networks and hubs in relation to other characteristics of the social and physical environment?
3. What is the distribution of criminal justice-supervised populations in relation to services they must access to fulfill their conditions of supervision?
4. What are the relationships among offenders, victims, and crimes across jurisdictional boundaries?
5. What is the increased predictive power of simulation models that employ cross-jurisdictional data?

This study was designed to evaluate the Defending Childhood Demonstration Program, a nationwide initiative to address children's exposure to violence. The Defending Childhood Demonstration Program sought to prevent children's exposure to violence, mitigate the negative impact of such exposure when it occurred, and develop and share knowledge about children's exposure to violence. The six sites chosen for the program evaluation were located in Boston, MA; Chippewa Cree Tribe, Rocky Boy's Reservation, MT; Cuyahoga County, OH; Grand Forks, ND; Rosebud Sioux Tribe, SD; and Shelby County, TN.

The evaluation consisted of a process evaluation and an impact evaluation. The impact evaluation examined the influence of Defending Childhood through a professional survey, a community survey, and analysis of core community indicators. The process evaluation portion of this study, which consists of qualitative data, is not available at this time due to confidentiality concerns.

Despite much recent attention devoted to understanding the ramifications of residential mobility, especially negative consequences for youth, there is scant research exploring how inner-city mobility impacts youth violence and victimization among minorities and immigrants. Leaving the city imparts benefits: decreasing deviance and improving youth outcomes. Considering that many are unable to "escape" the city, clarifying what effects, if any, inner-city mobility has is critical. Destination neighborhoods for youth who move in the city are either contextually the same, better, or worse than their original neighborhood. Evidence suggests that immigrant families are more likely to move as are racial minorities. Because of this, the researchers examined the extent to which moving within a city affects minority and immigrant youth experiences, particularly in relation to changes in neighborhood collective efficacy; a major characteristic shaping community crime rates and youth violence.

This project involved four main goals:

1. identify key characteristics of the destination neighborhoods and those who are moving within the city of Chicago;
2. understand how inner-city mobility of minority and immigrant youth affects engagement in violence and victimization;
3. determine whether vertical or horizontal mobility with respect to key neighborhood factors differentially influences minority and immigrant youth outcomes;
4. assess who fares better - youth who vertically move (to better or worse neighborhoods), those who do not move, or those who horizontally move (to equivalent neighborhoods).

This research used data from the Project on Human Development in Chicago Neighborhoods (PHDCN). Data were drawn from both the Longitudinal Cohort Study (N=1,611) and Community Survey (N=97). The rich data from the Community Survey affords the opportunity to examine how community characteristics like collective efficacy, disorder, and indicators of social disorganization can impact a variety of youth behaviors among at-risk youth over time between Wave 1 and Wave 2 and Wave 2 and Wave 3. The Longitudinal Cohort Study provides data on youth characteristics and experiences with violence, and ecological information on family and peer relationships. The investigators focused primarily on three of the seven youth cohorts from the Longitudinal Cohort Study: 9, 12, and 15. The ages of these youth during the study period place them at increased risk for exposure to community violence, and place them in range for aging into, peaking, or aging out of crime and delinquency.

The Longitudinal Cohort Study respondents are nested in neighborhood clusters and multilevel models are employed to assess the outcomes victimization and violence within neighborhood context. The researchers employed a series of hierarchical generalized linear models using HLM 7 in addition to running several analyses of variance (ANOVA) permitting examinations between groups of interest.

In late 2012, the New York City Department of Probation launched two large-scale reform initiatives: citywide adoption of a risk-needs assessment tool to support the integration of risk-need-responsivity principles into probation practice and the Neighborhood Opportunity Network (NeON), which established new offices and additional resources in neighborhoods with high numbers of probation clients.

Using a mixed-methods design, this study examines the impact of these probation innovations during the first three years of implementation and considers the implications of these findings for community supervision agencies nationwide. This study involves a quasi-experimental design with two major components: an interview study of probation client experiences and short-term outcomes after the launch of the new initiatives, with a focus on the impact of NeON; and an outcome evaluation examining criminal justice outcomes among three study groups: clients assigned to probation prior to the new initiatives (2010-2013), clients assigned to probation who received risk and need informed services via centralized probation offices (2013-2016), and NeON clients (2013- 2016).
