HR4125-119

Analysis under review: This bill has generated analysis that may be too generic or incomplete. Clause-level evidence remains available below.

Summary

This bill would dramatically expand the size of the U.S. House of Representatives by dividing the total population by 500,000 to determine the number of members, rather than keeping the current cap of 435 seats set in 1911. Based on the 2020 Census, this would roughly double the House to about 663 members. States would have the option to create multi-member districts and use ranked-choice voting for elections. If a future census causes the House size to change by more than 15%, a 15-member bipartisan commission would review the situation and recommend adjustments. The bill also authorizes funding for additional office space, staff, and resources needed for the expanded House.
