Final answer:
Each district has approximately 700,000 people to maintain equal representation, following the average number in U.S. congressional districts as stipulated by the Apportionment Act of 1911.
Step-by-step explanation:
This is because, by law, electoral districts must have roughly the same number of people to ensure equal representation in government. It’s based on a principle that aims to provide equitable political representation among the districts. This number can fluctuate slightly depending on the specific allocation of districts and states. For instance, as per some of the provided information, in the House of Representatives, the average number of citizens in a congressional district is now topping 700,000, which is a significant increase from the number advocated by George Washington, who endorsed several 30,000 for effective representation. The set limit of 435 representatives in the House was established by the Apportionment Act of 1911 due to concerns about physical space for the representatives and the efficiency of a larger Congress.
