The U.S. Census Bureau released population estimates showing significant growth in Southern and Sun Belt states, potentially favoring Republicans in the 2030 congressional map. Texas led with 391,243 new residents, while California saw a net decline of nearly 9,500. These shifts, driven largely by domestic migration, project gains in House seats for red-leaning states.
The U.S. Census Bureau’s Population and Housing Unit Estimates, released on Tuesday despite delays from last year’s government shutdown, highlight a demographic shift toward Southern and Sun Belt states. This migration trend is poised to benefit the Republican Party in the 2030 congressional reapportionment.
Texas topped the list with a population increase of 391,243 residents, or 1.2%, followed by notable gains in Florida and North Carolina. Nine states added more than 60,000 residents each, including Georgia, South Carolina, and Arizona. In contrast, five states experienced net declines, with California losing about 9,500 people.
Domestic migration drives these changes. California recorded the largest outflow at 229,077, followed by New York with 137,586 and Illinois with 40,017. North Carolina, Texas, and South Carolina saw the highest inflows. International migration boosted all states, led by Florida with 178,674 and Texas with 167,475 new residents.
Projections indicate Texas will gain four House seats, Florida two, and Arizona, Georgia, Idaho, North Carolina, and Utah one each. California faces a loss of four seats, while Illinois, New York, Oregon, Minnesota, Pennsylvania, Wisconsin, and Rhode Island each lose one. Analysts suggest this map would have added 11 electoral votes to a 2024 Republican presidential win.
The data fuels debates over census methods. Critics argue that counting non-citizens for apportionment inflates representation in Democratic-leaning states with large immigrant populations. "This is why Democrats are fighting so hard for illegal immigrants to stay in the country. The 2030 census is going to crush them as population is soaring in red states," tweeted Clay Travis on January 27, 2026.
Katie Pavlich echoed this, stating, "Illegal aliens are outrageously counted in the Census for Congressional representation. Even though they can't legally vote – they give Democrats more power in Washington D.C. That's why there is so much resistance from the Left on deportations."
A 2022 Census Bureau study revealed errors in the 2020 count: undercounts in Republican-leaning states like Arkansas, Florida, and Texas, and overcounts in Democratic ones like New York and Rhode Island. These discrepancies, linked to pandemic challenges, likely cost Florida and Texas additional seats.
