2010 United States Census Tract Community Type Classification and Neighborhood Social and Economic Environment Score for 2000 and 2010, from the Diabetes Location, Environmental Attributes, and Disparities (LEAD) Network (ICPSR 38645)
Released/updated on: 2023-03-07
Geographic coverage: United States
Time period: 2000-01-01--2011-10-01
This dataset contains two measures designed to be used in tandem to characterize United States census tracts, originally developed for use in stratified analyses of the Diabetes Location, Environmental Attributes, and Disparities (LEAD) Network. The first measure is a 2010 tract-level community type categorization based on a modification of Rural-Urban Commuting Area (RUCA) Codes that incorporates census-designated urban areas and tract land area, with five categories: higher density urban, lower density urban, suburban/small town, rural, and undesignated (McAlexander, et al., 2022). The second measure is a neighborhood social and economic environment (NSEE) score, a community-type stratified z-score sum of 6 US census-derived variables, with sums scaled between 0 and 100, computed for the year 2000 and 2010. A tract with a higher NSEE z-score sum indicates more socioeconomic disadvantage compared to a tract with a lower z-score sum. Analysts should not compare NSEE scores across LEAD community types, as values have been computed and scaled within community type.

Advancing the Understanding of Immigration, Crime, and Crime Reporting at the Local Level with a Synthetic Population, United States, 2019 (ICPSR 39318)
Released/updated on: 2026-04-16
Geographic coverage: United States
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.

These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.
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.

Census of Population and Housing, 2000 [United States]: 1998 Dress Rehearsal, P.L. 94-171 Redistricting Data, Geographic Files for 11 Counties in South Carolina, Sacramento, California, and Menominee County, Wisconsin (ICPSR 2913)
Released/updated on: 2006-01-12
Geographic coverage: Sacramento, United States, Columbia (South Carolina), California, Wisconsin, South Carolina
The 1998 Dress Rehearsal was conducted as a prelude to the United States Census of Population and Housing, 2000, in the following locations: (1) Columbia, South Carolina, and surrounding areas, including the town of Irmo and the counties of Chester, Chesterfield, Darlington, Fairfield, Kershaw, Lancaster, Lee, Marlboro, Newberry, Richland, and Union, (2) Sacramento, California, and (3) Menominee County, Wisconsin, including the Menominee American Indian Reservation. This collection contains map files showing various levels of geography (in the form of Census Tract Outline Maps, Voting District/State Legislative District Outline Maps, and County Block Maps), TIGER/Line digital files, and Corner Point files for the Census 2000 Dress Rehearsal sites. The Corner Point data files contain the bounding latitude and longitude coordinates for each individual map sheet of the 1998 Dress Rehearsal Public Law (P.L.) 94-171 map products. These files include a sheet identifier, minimum and maximum longitude, minimum and maximum latitude, and the map scale (integer value) for each map sheet. The latitude and longitude coordinates are in decimal degrees and expressed as integer values with six implied decimal places. There is a separate Corner Point File for each of the three map types: County Block Map, Census Tract Outline Map, and Voting District/State Legislative District Outline Map. Each of the three map file types is provided in two formats: Portable Document Format (PDF), for viewing, and Hewlett-Packard Graphics Language (HP-GL) format, for plotting. The County Block Maps show the greatest detail and the most complete set of geographic information of all the maps. These large-scale maps depict the smallest geographic entities for which the Census Bureau presents data -- the census blocks -- by displaying the features that delineate them and the numbers that identify them. These maps show the boundaries, names, and codes for American Indian/Alaska Native areas, county subdivisions, places, census tracts, and, for this series, the geographic entities that the states delineated in Phase 2, Voting District Project, of the Redistricting Data Program. The HP-GL version of the County Block Maps is broken down into index maps and map sheets. The map sheets cover a small area, and the index maps are composed of multiple map sheets, showing the entire area. The intent of the County Block Map series is to provide a map for each county on the smallest possible number of map sheets at the maximum practical scale, dependent on the area size of the county and the density of the block pattern. The latter affects the display of block numbers and feature identifiers. The Census Tract Outline Maps show the boundaries and numbers of census tracts, and name the features underlying the boundaries. These maps also show the boundaries and names of counties, county subdivisions, and places. They identify census tracts in relation to governmental unit boundaries. The mapping unit is the county. These large-format maps are produced to support the P.L. 94-171 program and all other 1998 Dress Rehearsal data tabulations. The Voting District/State Legislative District Outline Maps show the boundaries and codes for voting districts as delineated by the states in Phase 2, Voting District Project, of the Redistricting Data Program. The features underlying the voting district boundaries are shown, as well as the names of these features. Additionally, for states that submit the information, these maps show the boundaries and codes for state legislative districts and their underlying features. These maps also show the boundaries of and names of American Indian/Alaska Native areas, counties, county subdivisions, and places. The scale of the district maps is optimized to keep the number of map sheets for each area to a minimum, but the scale and number of map sheets will vary by the area size of the county and the voting districts and state legislative districts delineated by the states. The Census 2000 Dress Rehearsal TIGER/Line Files consist of line segments representing physical features and governmental and statistical boundaries. The files contain information distributed over a series of record types for the spatial objects of a county. These TIGER/Line Files are an extract of selected geographic and cartographic information from the Census TIGER (Topologically Integrated Geographic Encoding and Referencing) database. While the geographic coverage for a single TIGER/Line File is usually a county or statistical equivalent entity, the 1998 Dress Rehearsal TIGER/Line Files include only those entities included in the Dress Rehearsal with the coverage area based on January 1, 1998, legal boundaries. The Census's TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each 1998 Dress Rehearsal TIGER/Line File is designed to stand alone as an independent dataset. The TIGER/Line Files for each distinct geographic area can also be combined to show the entire area that was included in the Dress Rehearsal for that site. There are a total of 17 record types in the TIGER/Line Files, including the basic data record, the shape coordinate points, and geographic codes, that can be used with appropriate software to prepare maps. A complete list of codes for the record types can be found in Chapter 6 of the Technical Documentation for TIGER/Line Files (Part 603).

Part of the Census 2000 geographic product series, Census Tract Relationship Files (CTRF) show how 1990 census tracts relate to 2000 census tracts. The files consist of one record for each 1990 census tract/2000 census tract spatial set. A spatial census tract set is defined as the area that is uniquely shared between a 1990 census tract and a 2000 census tract. The CTRF consist of sets of four files for each of the United States and territories. The purpose of these files is to assist users in determining the relationships between 1990 and 2000 census tracts. Two of these files are state-level entity-based census tract relationship files, one providing a measurement of change based on population, the second measures change using street-side mileage. The other two files specifically list census tracts that have experienced significant change (2.5 percent or greater): one from the perspective of 1990 census tracts, the other from the perspective of Census 2000. A set of files for the United States as a whole is also provided.

The 1940 Census Tract files were originally created by keypunching the data from the printed publications prepared by the Bureau of the Census. The work was done under the direction of Dr. Donald Bogue, whose wife, Elizabeth Mullen Bogue, completed much of the data work. Subsequently, the punchcards were converted to data files and transferred to the National Archive and Records Administration (NARA). ICPSR received copies of these files from NARA and converted the binary block length records to ASCII format.

The 1950 Census Tract files were originally created by keypunching the data from the printed publications prepared by the Bureau of the Census. The work was done under the direction of Dr. Donald Bogue, whose wife, Elizabeth Mullen Bogue, completed much of the data work. Subsequently, the punchcards were converted to data files and transferred to the National Archive and Records Administration (NARA). ICPSR received copies of these files from NARA and converted the binary block-length records to ASCII format.

Crime in Metropolitan America: Patterns and Trends Across the Southern California Landscape, 2005-2012 (ICPSR 36681)
Released/updated on: 2025-12-16
Geographic coverage: United States, California
Time period: 2005-01-01--2012-01-01
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.

Geographic Base File/Dual Independent Map Encoding (GBF/DIME), 1980 (ICPSR 8378)
Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1978-01-01--1980-01-01
A Geographic Base File is a map in machine-readable form, and Dual Independent Map Encoding is the method used for this collection to encode map features in data files. These files have been created for most metropolitan areas. GBF/DIME does not contain individual house addresses, names, or other means of identifying individuals, and it does not contain statistical information. This collection provides a means to structure, compare, and display data, and relate this information to small geographic areas. ICPSR also has the Special Program Information Tape (SPIT) produced by the Census Bureau (See ICPSR 8372), which contains several computer programs designed for use with the GBF/DIME files.

Impact of Immigration on Ethnic-Specific Violence in Miami, Florida, 1997 (ICPSR 3872)
Released/updated on: 2005-11-04
Geographic coverage: United States, Florida, Miami
Does the rate of violent victimization differ across race and ethnic groups? In an effort to answer this question, this study sought to examine the violent victimization rate and the factors influencing ethnic-specific rates of violence in the city of Miami. Administrative data were obtained from the United States Bureau of the Census and the Miami Police Department Research Unit. For the groups of people identified as Afro Americans, Latinos, and Haitians, the numbers who were victims of aggravated assault and robbery in 1997 are included along with the assault and robbery rates for each group. The remaining variables are the percent of female-headed households, percent below poverty line, percent of young males out of the labor force and unemployed, residential instability, vacant and household instability, and the percent of 1980-1990 immigrants.

Innovative Methodologies for Assessing Radicalization Risk: Risk Terrain Modeling and Conjunctive Analysis, United States, 2001-2019 (ICPSR 38226)
Released/updated on: 2023-04-27
Geographic coverage: United States
Time period: 2001-09-11--2019-12-31
This study examined the geospatial contexts of where terrorism incidents occur, where terrorists plan and prepare for their crimes, and where terrorists reside in the United States. The researchers examined data linked to terrorism-related incidents in the United States from the time of the 9/11 terror attacks in 2001 through 2019. Using these data, the researchers applied innovative analytical methodologies of Risk Terrain Modeling (RTM) and Conjunctive Analysis of Case Configurations (CACC) to evaluate their utility in assessing risk of terrorism.
Risk terrain modeling is a method for identifying situational, place-based risk factors most associated with locations where terrorist incidents are likely to be planned or occur. This method looks at specific aspects of the physical landscape, such as locations of buildings or parking lots. The place-based analysis approach to terrorism investigation represents a shift from the conventional research emphasis on targeting suspicious persons by their demographic or other traits. This approach investigates the importance of location in explanations of crime and terrorism.
According to the American Terrorism Study, during this time between 2001 (after 9/11 and 2019) there were 296 terrorism incidents and 617 pre-incident activities occurred where the state was known. In addition, there were 420 known residences tied to terrorism-related incidents in particular states.

National Neighborhood Crime Study (NNCS), 2000 (ICPSR 27501)
Released/updated on: 2010-05-05
Geographic coverage: United States
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.)

Geographic coverage: United States
Time period: 1999-01-01--2013-12-31, 2010-01-01--2013-12-31
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.
