Final answer:
Congressional districts are created to have near 700,000 to 800,000 representations in order to ensure equal population distribution. The Apportionment Act of 1911 set a limit of 435 representatives in the House to avoid excessive size and to facilitate effective representation.
Step-by-step explanation:
Congressional districts are created so that each one has near 700,000 to 800,000 representations. This is because the population data gathered from the U.S. Census Bureau every ten years is used to allocate seats in Congress. The Apportionment Act of 1911 placed a limit of 435 representatives in the House, leading to the goal of having roughly equal populations in each congressional district.
