Introduction
There are three map series that relate to the geographic entities for which the Census Bureau provides statistics in the STF 1 data tapes. The Census Bureau will reproduce copies of these maps on electrostatic plotters in response to orders received by Customer Services, Data User Services Division, Bureau of the Census, Washington, DC 20233 (301-763-4100).

Map Descriptions
County Block Maps--These maps depict each county and statistically equivalent area on one or more map sheets at various scales, depending on the county's areal size and the density of the block pattern. (Most counties include multiple map sheets, including inset maps for densely settled areas.) The maps display block numbers and feature identifiers as well as the boundaries, names, and codes for the legal and statistical entities in the county. Each county includes an index map sheet that shows the locations of the map sheets comprising the county set.

Census Tract/Block Numbering Area Outline Maps
These county-based maps depict the boundaries and codes of census tracts or block numbering areas, the features and feature names underlying the boundaries, and the boundaries and names of counties, county sub-divisions, places, and American Indian/Alaska Native areas. Map scales vary to minimize the number of sheets. The maps may include one or more insets for densely settled areas. (The Census Bureau also intends to produce printed versions of these maps, for sale by the Government Printing Office (GPO), starting in 1992.)

County Subdivision Outline Maps
These State-based maps depict the boundaries and names of all counties and statistically equivalent areas, county subdivisions, places, and American Indian/Alaska Native areas. (The Census Bureau also will publish sectionalized versions of these maps in most 1990 census reports for each State.)
