RE: [CTPP] May 1 ? Fed Reg notice on Urbanized Areas

Kirk.. The geographynetwork site is independent of the Census Bureau site, and we have no information about the structure of their files. This is a question you will need to ask of ESRI. You will be able to create a state-county-census tract-block-UA/UC code from the UA Census 2000 TIGER/Line files by merging RT A and RT S (matching on CENID-POLYID for the merger) and then unduplicating on the code combination. (The state-county-tract-block codes are on RT S, and the UA code is on RT A, with the match key CENID-POLYID on both records.) Bob LaMacchia Geography Division U. S.

Fed Reg notice on Urbanized Areas Similar to Mr. Purvis' question: For each UA, will there be an index available with the 2000 Census Block "STFID" codes that make up the UA? STFID is a concatenated field containing FIPS State, FIPS County, 2000 Tract, and 2000 Block numbers. STFID was present in all Tract, Block Group, and Block files posted in the Census 2000 section of the Geography Network. Link to site: http://www.geographynetwork.com/data/tiger2000/ For example: A 2000 Census block in Maryland has STFID = 240010015021018 24 = County 001 = County 001502 = 2000 Tract Number 1018 = 2000 Block Number This index would allow a simple match to a county (or region / state) block file to determine 100% coverage of the UA.
