The city of Richmond itself had 186,000 in 2002 according to the statistics I found. However, the Greater Richmond area had 886,000 (this includes the surrounding counties of Chesterfield, Hanover, and Henrico.)
The other cities I've lived in:
Idaho Springs, Colorado: 1889
Denver, Colorado: 554,636
Craig, Colorado: 9,189
Phippsburg, Colorado: only has 50 homes and is unincorporated so the only data I could find was for the whole county which includes Steamboat Springs-14,088; the nearest town which is definitely larger than Phippsburg only has 850 people.
Powhatan, Virginia-22,843 (my parents still live there)
Athens, Georgia-140,372
Murray, Utah (suburb of Salt Lake City)-34,024
Of all the places I've lived, I'd say the small towns are definitely my favorite.
