The Census Bureau has prepared thousands of maps sheets which cover Pennsylvania in its entirety. There are several types of maps at various geographic levels. Each reference map measures three by four feet. All maps are $5.00 per map sheet, unless noted differently.

Census Block Maps

County Block Maps depict each county and statistically equivalent area on one or more map sheets. The scale and number of sheets are determined by the county's area, shape and the density of its block pattern. Large-scale inset maps provide detail for densely populated areas.

The maps illustrate features such as streets, rivers, and railroads. They include the names and boundaries for all county subdivisions, census designated places, and the 1990 census tracts, block numbering areas and blocks. Each county map set includes an index map sheet that identifies the locations of the map sheets comprising the county set.

The state set includes 2,527 map sheets. The chart on the following page indicates the number of map sheets per each county.

County Subdivision Maps

The County Subdivision Map is a single map sheet showing the names and boundaries of counties, county subdivisions, and census-designated places.

Voting District Outline Maps

Voting District Outline Maps display voting district boundaries only.

PL94-171 Block Maps

The PL94-171 Block Maps are identical to the County Block Maps but include voting district boundaries.

Census Tract/Block Numbering Area (BNA) Outline Maps

Census Tract/BNA Area Outline Maps are county-based maps with less detail than the County Block Maps. These maps display the boundaries of census tracts or BNAs. They also include the features and names underlying the boundaries an the names and boundaries of counties, county subdivisions, and census designated places. The number and scale of map sheets varies by county and larger-scale insets display densely settled areas. The chart shows the number of maps for coverage of each county. There are a total of 227 map sheets for the state at a tract level.
