Law Enforcement Agency Identifiers Crosswalk Project

Over the years BJS has funded the development of a set of databases in the Law Enforcement Agency Identifiers Crosswalk series. [The most recent of these is the 2005 version and can be obtained through the National Archive of Criminal Justice Data (ICPSR Study No. 4634).] These crosswalk files were designed to provide geographic and other identification information for each law enforcement agency included in either the Federal Bureau of Investigation's Uniform Crime Reporting (UCR) Program files or in the Bureau of Justice Statistics' Census of State and Local Law Enforcement Agencies (CSLLEA). These data have been used in the past by BJS and others to document, describe, characterize and study law enforcement agencies.

Under this award, NACJD will create a new and expanded Law Enforcement Agency Identifiers Crosswalk which will provide a wide range of detailed information on law enforcement agencies. These enhanced data will ideally range from agency identifiers, to law enforcement management statistics, to funding information, to detailed demographic and sociological information on the communities served.

The information will include all the data included in prior iterations of the crosswalk and enhance the data by linking new information such as the agency and the jurisdiction it serves to the federal funds they receive using to the Federal Assistance Award Data (FAAD) system. Finally, NACJD will develop an understanding of the current population-served estimates developed by the Census/FBI, assess the feasibility of replicating these estimates, and to (if possible) calculate new population-served estimates for various subpopulations.

NACJD will also be responsible for managing the project, assuring that all tasks are completed on time and in the manner specified. CA/NCF
