U.S. Census Federal Information Processing Standard (FIPS) state code. The Census Bureau treats the 5 states proper, plus the District of Columbia, as "states" for statistical reporting purposes. For records with recoded SAS match level (EHCV23) less than 6, this variable is generated with SAS proc geocode and proc ginside; and the SAS function STFIPS is used to convert twodigit state postal codes to FIPS state codes to fix missing values. The values for records with EHCV23 = 6 are 98 (foreign country) or 99. The count and values are suppressed (showing s) to protect the anonymity of respondents for public release.

Postal ZIP Code Identification Number (5digit) As defined by the U.S. Census Bureau, ZIP (Zone Improvement Plan) Code is a fivedigit code assigned by the U.S. Postal Service to a section of a street, a collection of streets, an establishment, structure, or group of post office boxes, for the delivery of mail. The Census Bureau uses only 5digit ZIP codes for the addresses and address ranges in most 2 Census. The 5digit ZIP code is current as of Jan 25 (U.S. ZIP codes source: zipcodedownload.com Jan 25, SAS Release 9.4M3. See SAS support website for detail: https://support.sas.com/rnd/datavisualization/mapsonline/html/misc.html). Occasionally, the ZIP code reported during interview differs from the ZIP code match found during geocoding, i.e., a data entry error. In such cases, the geocode matched or standardized ZIP code is kept in the data file. 87,647 93.6 5 99,925 Code Text ZIP code 99,998 5,822 6.8 99,999 Missing or none match or data error EHCV5 "METROPOLITAN STATISTICAL AREA" NUM(4.)

US Census Federal Information Processing Standard (FIPS) Place Code, as defined by the US Census Bureau, are "a concentration of population either legally bounded as an incorporated place, or identified as a Census Designated Place (CDP) including comunidades and zonas urbanas in Puerto Rico. Incorporated places have legal descriptions of borough (except in Alaska and New York), city, town (except in New England, New York, and Wisconsin), or village." Note that the Place FIPS code is unique within state. So, to uniquely identify a place, use the Place FIPS code in combination with the State FIPS code.

"The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of statistical data". "Census Tracts generally have a population size between,2 and 8, people, with an optimum size of 4, people. A census tract usually covers a contiguous area; however, the spatial size of census tracts varies widely depending on the density of settlement. Census tract boundaries are delineated with the intention of being maintained over a long time so that statistical comparisons can be made from census to census. Census tracts occasionally are split due to population growth or merged as a result of substantial population decline".

2325 Event History Calendar (EHC) BetweenWave Moves File EHCV9 "2 CENSUS BLOCK" NUM(4.) "Blocks (Census Blocks) are statistical areas bounded by visible features, such as streets, roads, streams, and railroad tracks, and by nonvisible boundaries, such as selected property lines and city, township, school district, and county limits and short lineofsight extensions of streets and roads. Generally, census blocks are small in area; for example, a block in a city bounded on all sides by streets. Census blocks in suburban and rural areas may be large, irregular, and bounded by a variety of features, such as roads, streams, and transmission lines". "Census blocks are numbered uniquely with a fourdigit census block number from to 9999 within census tract, which nest within state and county. The first digit of the census block number identifies the block group. Block numbers beginning with a zero (in Block Group ) are only associated with wateronly areas". see https://www.census.gov/geo/reference/gtc/gtc_block.html for more information on block codes.

"Block Groups (BGs) are statistical divisions of census tracts, are generally defined to contain between 6 and 3, people, and are used to present data and control block numbering. A block group consists of clusters of blocks within the same census tract that have the same first digit of their fourdigit census block number. For example, blocks 3, 32, 33,..., 3999 in census tract 2.2 belong to BG 3 in that census tract". "A BG usually covers a contiguous area. Each census tract contains at least one BG, and BGs are uniquely numbered within the census tract. Within the standard census geographic hierarchy, BGs never cross state, county, or census tract boundaries but may cross the boundaries of any other geographic entity". "BGs have a valid code range of through 9. BGs beginning with a zero only contain water area and are generally in coastal and Great Lakes water and territorial seas, but also in larger inland water bodies.

This variable contains a numeric value that indicates the relative accuracy of the geocode match. Each token within SAS match tokens (EHCV22) has an associated value, and the sum of these values makes up the value of SAS numeric quality of match (EHCV2).
