Live Here Data — A plain almanac of the fifty states.

Orientation facts for each US state: capital, largest city, census region, time zone, year of statehood and nickname. Compiled from standard public sources. Population rankings move, so read "largest city" as current-era rather than fixed. Laws and taxes by state are a separate matter — consult official state sites.
