How this is ranked
The Census Bureau's July 1 resident population estimates for 2025, largest first, with the change since 2020. Only metropolitan statistical areas of two or more counties are ranked (OMB Bulletin 23-01): a one-county area's figures are its county's, and micro areas are left out. An area that crosses a state line is ranked in each of its states. Areas without an estimate for the same year as the others are not ranked.
