Uniform Crime Reporting Program Data: County-Level Detailed Arrest and Offense Data, 2010
Notes on FIPS Codes
Cities designated by the Census Bureau as independent cities are reported separately and have their own "county" codes (see Appendix). Some jurisdictions, such as state parks and some state police, provide data only on a statewide basis. In these cases, data are allocated to counties proportionate to their share of the total state population. Parts 5 to 8 contain the amount of statewide data allocated to each county. To obtain the county total without the statewide allocation, the statewide values can be subtracted from the county data.

State Police data for Vermont were not reported within a county and the State Police data for Alaska and Connecticut are not allocated to the counties. These three State Police records are identified by the county code 999. In the 1997 data and onward another 999 county code was added to these data files. The New York/New Jersey Port Authority reported data in 1997 through two agencies, one in New York and one in New Jersey. The FBI included the New York Port Authority agency as part of New York county. However, the FBI did not assign a UCR county code for the New Jersey Port Authority and did not provide a population figure for the area covered by this jurisdiction. Therefore, the New Jersey/New York Port Authority (NJNYPOA) is a separate record in the data files from 1997 onward with a county code of 999. New York City Metro Transportation Authority (NY03083) is a separate record from 2007 onward with a county code of 999. From 2008, tribal agencies began to report offense data. Data for those agencies in each state will be in one record identified by the county code of 777.

ICPSR uses FIPS Publication 6-4 "Counties and Equivalent Entities of the United States, Its Possessions, and Associated Areas" from the National Institute of Standards and Technology (NIST), U.S. Department of Commerce, as a reference for assigning FIPS codes for the counties in this data collection. ICPSR consults this publication annually to note changes in FIPS codes that may affect this collection. The borough of Denali, Alaska (FIPS code 02068) was created from part of the Yukon-Koyukuk Census Area (FIPS code 02290) and unpopulated part of the Southeast Fairbanks Census Area (FIPS code 02240) effective December 7, 1990. The Denali Borough is NOT a record in the data. However, since no agency record from Denali was present in the original FBI data for either the arrest or crimes reported files, no data are missing from the ICPSR data. In May 1995, NIST announced that the independent city of South Boston, Virginia reverted to town status and became part of Halifax County as of June 30, 1995. The Virginia FIPS county code of 780 no longer exists and South Boston is included in FIPS county code 083. ICPSR did not adjust this data collection to reflect this change so that the data files would remain consistent with earlier years. Users who wish to use the current FIPS codes can combine the data from South Boston with Halifax County.

In July 1999, NIST announced that Yellowstone National Park, which had been treated as a county equivalent, is legally part of Gallatin County and Park County, Montana. Yellowstone National Park was left as earlier years. In July 1999, NIST announced that as of November 13, 1993 Dade County, Florida officially changed its name to Miami-Dade County.

The county was assigned a new FIPS code (086) to maintain the alphanumeric sequence of counties. In the 1997 data collection and onward, ICPSR also changed the Miami-Dade county code from 025 to 086 to match the change in the FIPS publication. However, the 1993-1996 UCR county-level data collections still used the old name and FIPS county code.

In July 2001, NIST announced that the independent city (county-equivalent) of Clifton Forge, Virginia, had reverted to town status, effective midnight, July 1, 2001. Clifton Forge is now an incorporated place within Alleghany County, rather than a separate county-equivalent surrounded by Alleghany County. This action will reduce the number of Virginia independent cities to 39 and the number of United States counties and equivalent areas to 3,141. The action reduces the total number of independent cities in the United States to 42. The FIPS county code of 560 for Clifton Forge, Virginia, is deleted. The FIPS-55 class code will change from C7 to C1. The census place code of 0285 and FIPS-55 code of 17440 are unaffected. The FIPS county code of 005 for Alleghany County remains unchanged. ICPSR did not adjust this data collection to reflect this change so that the data files would remain consistent with earlier years. Users who wish to use the current FIPS codes can combine the data from Clifton Forge with Alleghany County.

In January 2002, NIST announced that Broomfield County, Colorado, had been created from parts of Adams (001), Boulder (013), Jefferson (059), and Weld (123) counties effective November 15, 2001. The boundaries of Broomfield County reflect the boundaries of Broomfield city legally in effect on November 15, 2001. To maintain the alphanumeric sequence of counties, Broomfield County will have a code of 014 for FIPS 6-4, Counties and Equivalent Entities of the United States, Its Possessions and Associated Areas. ICPSR created county code 014 for Broomfield County to match the change in the FIPS publication.
