The Role of Block- Level Data

Census blocks are the smalgett geographic units used by the Census Bureau. They can bee as small as a city block in urban areas or as square mil in rural areas.

From Cresus to Congress: Te Repportionment Mechanismus

After each census, thee Creass Bureau calculates thee apportionment of House seats using thae method of equal propors. Thee 2020 census, for exampla, resulted in seven states gaining seats (Colordo, Florida, Montana, North Carolina, Oregon, Texas) and seven states losing seats (Curnia, Curnia, Curnia, Curgogan, New York, Ohio, Pensylvania, Wegt Virginia).
