Summary File 1 (SF 1) is released as individual files on a flow basis for each of the 50 states, the District of Columbia, and Puerto Rico; and then for the United States as a whole, and includes summaries for states, metropolitan areas and other higher levels of geography in a single file. The tables (matrices) are identical for all files, but the geographic coverage differs.

SPEAKER NOTES: Urban and rural areas will not be available until 2002 as part of the final national file; an advance national file that provides all SF 1 data without the urban and rural components will be released in late 2001 . The Census Bureau is currently reviewing its criteria for urban/rural delineations and will be announcing the official decision in the 2nd quarter of 2002.
