Census 2000 Summary File 1
This file is a modification of the original release of the data from the Census Bureau. All 40 files have been combined into 1 file, with the exception of several large states. For these states, multiple files were written out.
The resulting file is hierarchical in structure because not all tables are available for each summary level. All tables are available for census tracts and higher levels of geography, such as places, counties, states, and metropolitan areas. However, only selected tables are available for blocks and block groups.
A SAS Program has been provided to help users read the heirarchial data file.The only input needed from the users end are statements flagging desired geographic and summary level selection.
If you are interested in these files proceed to the next section. If you need further information on the address of our anonymous ftp site or how to uncompress data refer to either FTP or uncompressing data .
