The TIGER dataset from the US Census Bureau provides a variety of geospatial data for different years (2010, 2016, 2018, 2020) and geographical units, including states, counties, census tracts, block groups, and blocks.

These datasets can be used to analyze demographic information, urban development, and other spatial patterns across the United States, Puerto Rico, and Island Areas.

Data is provided as polygon features (e.g., for states, counties, tracts) or line features (e.g., for roads) and sometimes aggregated with demographic profile data (like Demographic Profile 1 for census tracts).

Census blocks are the smallest geographical units in the TIGER dataset, roughly equivalent to a city block, while block groups and tracts aggregate blocks into larger neighborhood-like areas.

While most datasets represent geographical boundaries, some, like TIGER: US Census 5-digit ZIP Code Tabulation Areas, provide approximations of postal service zones.
