NAVTEQ Census Boundaries details:
NAVTEQ Census Boundaries are polygon files of Census blocks, block groups and tracts that align with NAVTEQ NAVSTREETS™. The Census Bureau, usually in cooperation with State and local agencies, establishes, identifies and delineates these geographic statistical areas.
Census blocks are the smallest geographic area for which the US Census Bureau collects and tabulates decennial census data. Census block boundaries are formed by streets, railroads, streams and other bodies of water, visible physical and cultural features, and other legal boundaries.
Census data for these areas serve as the basis for valuable small-area geographic studies. Census blocks generally contain between 0 and 600 people. There are many blocks that contain no population, like 67% of the blocks in the State of Wyoming.
A census block group is a cluster of census blocks having the same first digit of their four-digit identifying numbers within a census tract. Block groups generally contain between 600 and 3,000 people, with an optimum size of 1,500 people.
Block groups never cross the boundaries of states, counties or statistically equivalent entities, except American Indian hierarchy. Block groups never cross the boundaries of census tracts, but may cross the boundary of any other geographic entity required as a census block boundary.
Census tracts are small, relatively permanent statistical subdivisions of a county. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of decennial census data. Census tracts generally have between 1,500 and 8,000 people, with an optimum size of 4,000 people. Counties with fewer people have a single census tract.
Census tract boundaries are delineated with the intention of being maintained over many decades so that statistical comparisons can be made from decennial census to decennial census. However, physical changes in street patterns caused by highway construction, new developments, and so forth, may require occasional boundary revisions. In addition, census tracts occasionally are split due to population growth or combined as a result of substantial population decline.
