Michigan has 13 representatives in the U.S. House and 110 representatives in the Michigan House of Representatives. On the Senate side, the state has two U.S. senators and 38 state senators. The federal number isn’t fixed forever: Michigan lost a U.S. House seat after the 2020 Census, dropping from 14 to 13.
Michigan’s 13 U.S. House Seats
Michigan holds 13 of the 435 seats in the U.S. House of Representatives.1U.S. Census Bureau. Congressional Apportionment 2020 Census Briefs Each member represents a single congressional district of roughly 775,000 residents and works in Washington, D.C., voting on federal legislation and serving on committees that handle everything from defense spending to environmental policy.
Every federal representative serves a two-year term and stands for re-election in each even-numbered year. The Constitution requires House members to be “chosen every second Year by the People of the several States.”2Congress.gov. Constitution Annotated – Article I Section 2
The delegation shrank from 14 to 13 after the 2020 Census showed Michigan’s population growth lagging behind faster-growing states. That change took effect with the 2022 elections, when candidates ran in newly drawn 13-district maps for the first time.3U.S. Census Bureau. 2020 Census Apportionment Results
110 Members in the Michigan State House
At the state level, the Michigan House of Representatives has 110 members, each elected from a single-member district drawn on the basis of population.4Michigan Legislature. Michigan Constitution of 1963 Article IV 3 – Representatives, Number, Term With a statewide population just above 10 million, that works out to roughly 91,000 residents per district. These lawmakers meet at the State Capitol in Lansing and handle matters the federal government doesn’t touch directly, including state tax rates, K-12 education standards, road funding, and criminal sentencing.
Like their federal counterparts, state representatives serve two-year terms and face voters every even-numbered November.
38 Seats in the Michigan Senate
Michigan’s upper legislative chamber has 38 senators, each representing a district of roughly 247,000 to 273,000 residents.5Michigan Senate. General Information Senators serve four-year terms that run concurrently with the governor’s term, so all 38 seats appear on the ballot in the same cycle as the governor’s race. The Senate shares lawmaking power with the House; a bill must pass both chambers before it reaches the governor’s desk.
Why the Federal Count Changes
The number of federal seats Michigan holds is recalculated after every decennial census. The U.S. Census Bureau counts the population in years ending in zero, and those figures determine how the 435 House seats are divided among the 50 states.6U.S. Census Bureau. About the Decennial Census of Population and Housing The process, called apportionment, uses a formula known as the method of equal proportions. Once the President transmits population figures to Congress, each state’s seat count is locked in until the next census.7Office of the Law Revision Counsel. 2 USC 2a – Reapportionment of Representatives
Michigan’s trajectory tells the story. The state peaked at 19 House seats in the 1960s and 1970s, when its auto industry powered rapid population growth. Since then, slower growth relative to Sun Belt states has cost the delegation seats in nearly every reapportionment cycle. The 2020 Census recorded Michigan’s population at about 10.08 million, enough to hold only 13 seats rather than the 14 it had after 2010.1U.S. Census Bureau. Congressional Apportionment 2020 Census Briefs The state-level counts of 110 House members and 38 senators, by contrast, are fixed in the Michigan Constitution and don’t shift with the census; only the district lines are redrawn.
