New Hampshire enacted new state house districts on March 23, 2022, when Gov. Chris Sununu (R) signed a proposal approved by both legislative chambers into law. The maps will take effect for New Hampshire’s 2022 state legislative elections.
The New Hampshire House passed a map on Jan. 5 in a 186-168 vote, which the Senate then approved on Feb. 16 in a 14-10 vote. The House Redistricting Committee initially advanced the proposal on Nov. 16, 2021.
As of March 25, 41 states have adopted legislative district maps for both chambers, one state has adopted maps that have not yet gone into effect, and one state has adopted maps for one legislative chamber. The state supreme court in one state has overturned previously enacted maps, the U.S. Supreme Court has blocked previously enacted maps in one state, and five states have not yet adopted legislative redistricting plans after the 2020 census.
Nationwide, states have completed legislative redistricting for 1,742 of 1,972 state Senate seats (88.3%) and 4,594 of 5,411 state House seats (84.9%).
