Final answer:
Each congressional district is represented by one member in the House of Representatives, with an average of approximately 700,000 citizens per district, following the fixed cap of 435 members set by the Apportionment Act of 1911 and the Permanent Apportionment Act of 1929.
Step-by-step explanation:
The number of people represented per district by a member of the House of Representatives is approximately 700,000. This ratio has increased significantly from the time of the first U.S. Congress, when there were sixty-five representatives, each representing about thirty thousand citizens. With the growth of the U.S. population, the Apportionment Act of 1911 and the Permanent Apportionment Act of 1929 were passed, setting a fixed number of 435 members in the House. As a result, after each decennial census, these 435 districts are apportioned based on the population data, aiming for roughly equal populations per district. States with smaller populations have a minimum of one representative, such as Alaska and Wyoming, while more populous states like California have more representatives, reflecting their larger populations.
