Senator vs. Representative: What's the Difference?

Edited by Harlon Moss || By Janet White || Updated on December 20, 2023
A senator is a member of the Senate, part of the upper chamber in a bicameral legislature, while a representative is a member of the lower chamber, like the House of Representatives.

Key Differences

Senators serve in the Senate, which is typically the upper chamber in a bicameral legislative system, and represent broader constituencies, often entire states. Representatives, on the other hand, serve in the lower chamber, such as the House of Representatives, representing smaller, specific districts within a state.
The number of senators in a legislature is usually smaller and fixed, often two per state, regardless of the state's population. In contrast, the number of representatives is usually larger and proportionate to the population of their districts.
Senators often have longer terms in office, such as six years in the United States, allowing for a more extended focus on long-term policy. Representatives typically serve shorter terms, like two years in the U.S., leading to a closer connection with their local electorate's immediate concerns.
The role of a senator often includes broader legislative responsibilities, and they may have a significant say in foreign policy and high-level government appointments. Representatives usually focus on more specific, local issues pertinent to their constituents.
Senators, due to their smaller number and larger constituencies, may have more influence on national policy and greater visibility. Representatives often have more direct interaction with their constituents and may be more responsive to local needs.
