St. Petersburg Demographics

St. Petersburg had an estimated 266,153 residents on April 1, 2025, according to the state, which makes it the largest city in Pinellas County.

The Florida Office of Economic and Demographic Research lists St. Petersburg at 266,153 people on April 1, 2025, a gain of 7,845 over its April 1, 2020 Census count of 258,308; the same table counts 350 inmates inside the city total (Florida Office of Economic and Demographic Research, April 1, 2025 estimates). Pinellas County as a whole stood at 966,933, and the next largest cities were Clearwater at 118,327 and Largo at 84,075 (Florida Office of Economic and Demographic Research, April 1, 2025 estimates). By that table, St. Petersburg holds a little over a quarter of the county's people (27.5 percent, calculated from the two totals).

The Census Bureau's American Community Survey gives a different total, 262,732 residents (ACS 2020-2024, DP05), because it is a five-year survey estimate covering 2020 through 2024, while the state figure is an estimate for one date, April 1, 2025. Both are shown here with their labels; the shares, medians and rates on the rest of this page (age, origin, income, housing) all come from the ACS 2020-2024. The ACS county total for the same period is 963,481 (Pinellas County, DP05).

Not every Pinellas city grew. Several Pinellas beach towns lost residents between 2020 and 2025 in the state table, including St. Pete Beach, down 455 to 8,424, and Treasure Island, down 481 to 6,103, while St. Petersburg and Pinellas Park gained (Florida Office of Economic and Demographic Research, April 1, 2025 estimates).
