Census: A census is a national survey conducted every ten years that collects data about the population's demographic characteristics such as age, race/ethnicity, and gender. Census data helps determine how congressional districts are redrawn.
Redistricting: Redistricting is the process of redrawing voting district boundaries after each census to account for changes in population and ensure equal representation. This typically occurs every ten years.
Single-Member Districts: Single-member districts are voting districts that elect only one representative, such as a member of Congress. Each district sends a single representative to the legislative body.
