Capital Punishment in the United States - Capital Punishment in the
United States provides annual data on prisoners under a sentence of death, as
well as those who had their sentences commuted or vacated and prisoners who
were executed. This study examines basic sociodemographic classifications
including age, sex, race and ethnicity, marital status at time of imprisonment,
level of education, and State and region of incarceration. Criminal history
information includes prior felony convictions and prior convictions for criminal
homicide and the legal status at the time of the capital offense. Additional
information is provided on those inmates removed from death row by yearend.

Expenditure and Employment for the Criminal Justice System
-These data collections present public expenditure and employment data
pertaining to criminal justice activities in the United States. Information on
employment, payroll, and expenditures is provided for police, courts,
prosecutors' offices, and corrections agencies. Specific variables include
identification of each government, number of full- and part-time employees, level
of full- and part-time payroll, current expenditures, capital outlay, and
intergovernmental expenditures. Two different data collections are included: the
Criminal Justice Expenditure and Employment Extracts and the Criminal Justice
Expenditure and Employment Survey. The CJEE Extracts have been extracted
from the Census Bureau's Annual Government Finance Survey and Annual
Survey of Public Employment since 1982. The CJEE Survey collected detailed
annual data for 1971 to 1979, and for 1985, 1988, and 1990, but has been
discontinued. The CJEE Extracts data are similar to but not statistically
comparable to the CJEE Survey data.

Geographical Information Systems - In 1997 National Institute of Justice
(NIJ) established the Mapping and Analysis for Public Safety (MAPS) Program,
formerly known as the Crime Mapping Research Center (CMRC) for the the
promotion, research, evaluation, development, and dissemination of Geographic
Information Systems (GIS) technology and the spatial analysis of crime. Since
then, NIJ has sponsored the development of GIS resources, conducted a survey
on the usage of GIS in law enforcement, and funded research projects that
utilize GIS.

Homicide - This Homicide Data Resource Guide was designed by the National
Archive of Criminal Justice Data (NACJD) staff to provide easy access to data
collections related to homicide. For instance, it provides quick links to certain
types of homicide studies and links to studies available for online data analysis.
This resource guide also provides useful information for secondary analysis of
NACJD data collections, such as customized help for complex data collections,
information on how to obtain restricted access data, and links to funding
opportunities and publications.

Law Enforcement Management and Administrative Statistics -
These surveys were first collected in 1987 and are administered approximately
every three years. They present information on law enforcement agencies in the
United States: state police, county police, special police (state and local),
municipal police, and sheriff's departments. Variables include size of the
population served by the police or sheriff's department, levels of employment
and spending, various functions of the department, average salary levels for
uniformed officers, policies and programs, and other matters related to
management and personnel.

National Incident-Based Reporting System - The National Incident
Based Reporting System (NIBRS) is an incident-based reporting system for
crimes known to the police. For each crime incident coming to the attention of
law enforcement, a variety of data are collected about the incident. These data
include the nature and types of specific offenses in the incident, characteristics
of the victim(s) and offender(s), types and value of property stolen and
recovered, and characteristics of persons arrested in connection with a crime
incident.
Incident-based data provide an extremely large amount of information about
crime. The information is also organized in complex ways, reflecting the many
different aspects of a crime incident. Therefore this Web site provides a
Resource Guide for learning about, accessing and using NIBRS data.

National Crime Victimization Survey - The National Crime Victimization
Survey (NCVS) series, previously called the National Crime Survey (NCS), has
been collecting data on personal and household victimization since 1973. An
ongoing survey of a nationally representative sample of residential addresses,
the NCVS is the primary source of information on the characteristics of criminal
victimization and on the number and types of crimes not reported to law
enforcement authorities. It provides the largest national forum for victims to
describe the impact of crime and characteristics of violent offenders. Twice each
year, data are obtained from a nationally representative sample of roughly
49,000 households comprising about 100,000 persons on the frequency,
characteristics, and consequences of criminal victimization in the United States.
The survey is administered by the U.S. Census Bureau (under the U.S.
Department of Commerce) on behalf of the Bureau of Justice Statistics (under
the U.S. Department of Justice).
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. The survey categorizes crimes as "personal" or "property."
Personal crimes cover rape and sexual attack, robbery, aggravated and simple
assault, and purse-snatching/pocket-picking, while property crimes cover
burglary, theft, motor vehicle theft, and vandalism. The data from the NCVS
survey are particularly useful for calculating crime rates, both aggregated and
disaggregated, and for determining changes in crime rates from year to year.
