Census Boundaries

Definition

Census Boundaries refer to the official geographic divisions used to organize and report demographic, economic, and housing data during national censuses. These include political subdivisions like states and municipalities, as well as statistical units such as census tracts, blocks, block groups, and enumeration districts.

Application

GIS applications often overlay these boundaries on thematic maps to analyze trends such as income distribution, age, and housing density.
