The U.S. Census Bureau provides the 50 states, the District of Columbia, and Puerto Rico with population counts to use in their redrawing of congressional and state legislative district boundaries — a process known as “redistricting.”
While the states are responsible for legislative redistricting, the Census Bureau provides population counts possible for the geographic areas the states need.
