Arizona would gain one seat in the House of Representatives if 2018 census data were used for apportioning congressional seats today, according to a political consulting firm.
The 435 seats in the House are reapportioned every 10 years based states’ population size, with the most populous states getting the largest share of seats.
The next reapportionment will occur in 2020.
Election Data Services said in a press release Wednesday that projections for census data in 2020 show a possibility for even greater change.
Based on 2018 data, 13 states’ congressional delegations would be impacted, but by 2020 three additional states are expected to be affected.
