^ An out-of-state area and its population are displayed in green. An area that extends into more than one state is displayed in purple. A purple population number over a black population number show the total population versus the in-state population. The state's abbreviation is also shown next to the in-state total.^ For PSAs comprising populations from multiple states, they are listed twice to show both their intrastate population within that PSA as well as the PSA's total population. Only the intrastate population is ranked. ^ a b c d Revised Delineations of Metropolitan Statistical Areas, Micropolitan Statistical Areas, and Combined Statistical Areas, and Guidance on Uses of the Delineations of These Areas (July 21, 2023).
