TIGER includes both land features such as roads, rivers, and lakes, as well as areas such as counties, census tracts, and census blocks. Some of the geographic areas represented in TIGER are political areas, including state and federally recognized tribal lands, cities, counties, congressional districts, and school districts.
A census block is the smallest geographic unit used by the United States Census Bureau for tabulation of 100-percent data (data collected from all houses, rather than a sample of houses). The number of blocks in the United States , including Puerto Rico and other island areas, for the 2020 Census was 8,180,866.
A census tract, census area, census district or meshblock [1] is a geographic region defined for the purpose of taking a census. [2] Sometimes these coincide with the limits of cities , towns or other administrative areas [ 2 ] and several tracts commonly exist within a county.
A census-designated place (CDP) [1] [2] [3] is a concentration of population defined by the United States Census Bureau for statistical purposes only.. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, [4] such as self-governing cities, towns, and villages, for the purposes of gathering and correlating statistical data.
Individual USPS ZIP codes can cross state, place, county, census tract, census block group and census block boundaries, so the Census Bureau asserts that "there is no correlation between ZIP codes and Census Bureau geography". [2] Moreover, the USPS frequently realigns, merges, or splits ZIP codes to meet changing needs.

RUCAs are a classification scheme that use the standard Census Bureau urban area definitions in combination with commuting information to characterize all of the nation's census tracts. Census tracts are used to establish RUCAs because they are the smallest geographic building block for which reliable commuting data are available.
