The primary purpose of the second wave of the National Neighborhood Crime Study (NNCS2) was to develop a panel dataset of serious reported crimes in urban neighborhoods circa two time points - 2000 and 2010. These data offer the opportunity to assess the sources and consequences of neighborhood crime change for "communities" of different ethno-racial and economic compositions across the United States. The study also sought to examine the role of a neighborhood's broader ecology on crime levels and crime change by integrating indicators of city and/or metropolitan conditions. The NNCS2 includes two datasets. The first dataset, the NNCS2-Panel file (NNCS2-P), contains information on the Federal Bureau of Investigation's (FBI) Part 1 Index crimes (except arson), socioeconomic and demographic characteristics, and a variety of other neighborhood and city level controls for circa 2000 and 2010 for tracts in 81 of the 91 cities in the NNCS, wave 1. The second dataset, the NNCS2-Cross-Sectional file (NNCS2-CS), allows for examination of the local and contextual sources of neighborhood crime inequality circa 2010. The NNCS2-CS incorporates parallel data for census tracts and cities as in the Panel file, but includes a few additional cities for which panel data could not be compiled, as well information on the metropolitan areas within which cities are located.
National Neighborhood Crime Study (NNCS), 2000
The primary purpose of the National Neighborhood Crime Study (NNCS) was to assemble tract-level crime and sociodemographic data for cities across the United States in order to permit analyses of the sources of crime for "communities" of different racial-ethnic and class composition. The NNCS also sought to examine the extent to which the causes of crime in communities are contingent on the types of geographic region, labor market, or other contextual characteristics. To fulfill these purposes, the NNCS compiled crime and sociodemographic data for census tracts in a representative sample of large United States cities for 2000. The dataset includes: (1) tract-level crime data pertaining to seven of the FBI's crime index offenses; (2) tract-level information on social disorganization, structural disadvantage, socioeconomic inequality, mortgage lending, and other control variables garnered from the 2000 United States Census of Population and Housing Summary File 3 (SF3) and other publicly available sources; (3) city-level information for the city in which the tract is located, focused on labor market structure, socioeconomic inequality, population change, and other control variables; and (4) metropolitan area data for the Metropolitan Statistical Area (MSA) or Primary Metropolitan Statistical Area (PMSA) in which the tract is located, focused on labor market structure, socioeconomic inequality, population change, and other control variables (also taken from the 2000 Census and other publicly available sources). The NNCS contains data for 9,593 census tracts in 91 cities in 64 metropolitan areas. (Please see the collection note section for additional information about variable naming.)
