According to recently released figures from the U.S. Census Bureau, Pinal County is holding onto its status as one of the fastest-growing counties in the nation, gaining more residents during 2023 than in the previous year.
The bureau’s analysis of net domestic migration, or the number of people moving into the county from somewhere else within the U.S. versus those moving out, found Pinal gained 17,473 residents, or the seventh-highest inflow in the U.S. This metric excludes other factors including births, deaths and immigration.
The highest net migration for 2023 was reported for Polk County, Florida, southwest of Orlando, at 26,029. Los Angeles County in California reportedly had the highest negative net migration at 119,037.
Pinal County’s net migration for 2022 was 14,075, proving its drawing power is growing as larger employers like LG Energy Solutions and Procter & Gamble announce big plans that take advantage of its strategic location on Interstate 10 between Phoenix and Tucson.
The new total estimated population is 484,283
Maricopa County had the fourth-largest overall population increase in the nation at 30,238, falling from first place in 2022. It remains the nation’s fourth-largest county overall.
