How is population change reflected in the House of Representatives?

Population change is reflected in the House of Representatives primarily through the addition of new districts and representatives. This process is directly related to the decennial census conducted every ten years, which counts the population in each state. Based on the census results, seats in the House are apportioned among the states according to their population. If a state experiences population growth, it may gain additional congressional districts and representatives, while states with declining populations may lose seats.

This approach ensures that representation in the House aligns with the current population distribution across the country, making it a key mechanism for maintaining representative democracy. The other choices do not directly relate to how population changes affect House representation. Presidential elections and changes in the voting age deal with different aspects of the political process, while the number of senators remains fixed at two per state and does not change with population.
