September 2020 breakdown of state legislative party membership: 52.0% Republicans, 46.8% Democrats

According to Ballotpedia’s September partisan count of the 7,383 state legislators across the United States, 52.01% of all state legislators are Republicans and 46.77% are Democrats.

Ballotpedia tallies the partisan balance of state legislatures at the end of every month. This refers to which political party holds the majority of seats in each chamber. Republicans hold a majority in 59 chambers and Democrats hold a majority in 39 chambers. Alaska’s chamber is the only one to have a power-sharing agreement between the two parties.

Nationally, the state legislatures include 1,972 state senators and 5,411 state representatives. Republicans hold 1,081 state Senate seats—remaining the same since August — and 2,759 state House seats — up one from last month. Democrats hold 3,453 of the 7,383 state legislative seats—874 state Senate seats (down one seat) and 2,579 state House seats (the same as last month). Independent or third-party legislators hold 34 seats, of which 30 are state House seats and four state Senate seats. There are 56 vacant seats.

In the September prior to the 2016 general election, Democrats held 821 state Senate seats (53 fewer than today) and 2,334 state House seats (a decrease of 245), while Republicans held 1,087 state Senate seats (an additional six when compared to today) and 3,017 state House seats (an increase of 258).
