The House is much larger than the Senate, with 435 members compared to the Senate's 100. This difference reflects the principle of representation based on population, with the House giving more weight to populous states.
Representatives serve two-year terms, while Senators serve six-year terms. This difference gives Senators more time to build expertise and relationships, potentially fostering a more deliberative body.
Representatives are elected from single-member districts, leading to more geographically concentrated representation and potentially encouraging responsiveness to local concerns. Senators are elected statewide, promoting broader perspectives and potentially encouraging a focus on national issues.
