How this is ranked
The percentage change in the Census Bureau's July 1 resident population estimates between 2020 and 2025, with the number of people added. 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. Areas without a figure for the same period as the others are not ranked. An area that crosses a state line is ranked in each of its states.
