2000 Perinatal File Geographic Code Outline The following pages show the geographic codes used by the Division of Vital Statistics in the processing of vital event data occurring in the United States. For the perinatal data set, counties and cities with a population of 250,000 or more are identified. Federal Information Processing Standards (FIPS) State, County, and City/Place Codes: For the 2000 perinatal file, the county and city/place codes and the State code immediately preceding them are FIPS codes. These codes were effective with the 1996 data year and are based on the results of the 1990 Census. County and county equivalents (independent and coextensive cities) are numbered alphabetically within each State. When an event occurs to a nonresident of the United States, residence data are coded only to the "State" level, or to the remainder of the world. For an explanation of FIPS codes, reference should be made to various National Bureau of Standards (NBS) publications. - 1 -
