A Congressional District is a specific geographic area within a state that elects a representative to the United States House of Representatives. Each state is divided into districts based on population, ensuring that each representative serves approximately the same number of constituents. The total number of districts is 435, and they are redrawn every ten years following the census to reflect changes in population. These districts play a crucial role in the legislative process, as representatives advocate for the interests of their constituents in Congress. The boundaries of each district can influence political representation and party dynamics, making the drawing of district lines, known as redistricting, a significant political issue.
