The MPSI Census 2000 Boundaries data provides the information you need to perform a detailed evaluation of markets down to the smallest available U.S. census geographic area, the block. It also provides additional census boundaries, allowing you to perform GIS analysis for a variety of geographic sizes.
The boundaries included in this product are:

• Block Groups - A collection of census blocks within a census tract.
• Census Tracts - These small statistical subdivisions of counties contain an average of about 4,000 persons.
• Counties & Equivalent Areas - These are the primary divisions of most states. They include counties in 48 states; parishes in Louisiana; boroughs and census areas in Alaska; and independent cities in Maryland, Missouri, Nevada and Virginia.
• States - Includes boundaries for all 50 states.
