Why do some states have more representatives than others?

The number of representatives a state has in the U.S. House of Representatives is primarily determined by the state's population. This is in line with the principle of proportional representation established in the Constitution. The total number of representatives is divided among the states based on the results of the decennial census, which counts the population in each state. States with larger populations receive more representatives, ensuring that their voices are adequately represented in Congress.

In contrast, options related to historical significance, geographic size, or the number of senators do not influence the allocation of representatives. While larger states often have more historical significance or geographic size, these aspects do not affect the number of representatives. Additionally, each state has two senators irrespective of its population, so the number of senators has no bearing on the number of representatives a state can have in the House. Thus, population is the key factor driving the distribution of representatives among the states.
