The National Justice Agency List is a master name and address file created and maintained by the United States Bureau of the Census for the Bureau of Justice Statistics. The file was first created in 1970, and the Census Bureau has continued to maintain and expand the file. The master file contains information for ten separate sectors: prosecution and civil attorneys, public defenders, law enforcement, courts, probation and parole, juvenile corrections, local adult corrections, state adult corrections, other justice agencies, and federal and Indian tribal agencies. ICPSR has separated the master file into ten subfiles, corresponding to the ten sectors in the master file. Each file has variables containing the names and addresses of agencies in that sector and information relevant only to the agencies within the sector. Court (Part 1) variables include court structure, type of jurisdiction, and the location of court records. State Adult Correctional Facilities (Part 2) variables include type of institution, agency employment size, sex of inmates, and funding code. Public Defender Agencies (Part 3) variables include type of agency, type of cases handled, agency employment size, and funding code. Probation and Parole Agencies (Part 4) variables include type of system, agency client caseload, agency employment size, and funding code.
