Congressional Districts are specific geographic areas within a state that elect representatives to the United States Congress. Each state is divided into these districts based on population, ensuring that each representative serves roughly the same number of constituents. The total number of districts is 435, with each state receiving at least one district. The process of drawing these districts is called redistricting, which occurs every ten years after the U.S. Census. This process can influence political power and representation, as districts may be shaped to favor one political party over another, a practice known as gerrymandering.
