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.
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
recovered, and characteristics of persons
arrested in connection with a crime

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.

States - Capital Punishment in the United
States provides annual data on prisoners

basic sociodemographic classifications
level of education, and State and region

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 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.
