----------------------------Original message---------------------------- <start> The "Archive of Census Related Products", located at ftp ftp.ciesin.org cd /pub/census contains new files. Please read the files "archive.ann" and "archive2.ann" for contents information on the entire Archive. o Census Block Statistics Data from the Summary Tape File (STF1B). The Archive already contained boundary files in the directory trees /pub/census/usa/tiger/??/bnablk/ where ?? marks state postal codes. From the STF1B database (Bureau of the Census, cdrom media) data were extracted and written out in ascii CSV files by county. Each record contains a polygon identification field (POLID) which will match POLID from the boundary files extracted from TIGER92. Population items include Total Population, Age, Race, and Hispanic Origin. Housing items include Number of Housing Units, Tenure, Room Density, Mean Contract Rent, Mean Value, and Mean Number of Rooms. (Some data items are fairly limited in descriptive information). The records also contain relevant information from the Geographic Header Records. This information includes items such as area land, area water, centroids, Metropolitan Statistical Area Codes, Place Codes, and Special Area Codes. Also posted are "Zero Population and Housing Unit Counts" (zph) datafiles identifying the non-populated census blocks. Geographic Header information is included. The directories /pub/census/usa/stf/us/[xblk,zblk]/ contain links to all US files for convenient retrieval of all state-county files. <end>
