| In 1790, the U.S. capital was still in Philadelphia,
so there was no 1790 DC census. In 1791, the District of Columbia
was formed from Montgomery and Prince George's Co., MD. Based on
the indices at Ancestry.com: in 1800, the population of DC was a
mere 1166; no 1810 scedules are extant; in 1820, the population is still
only 5103; in 1830, it's 6569; in 1840, it's an inexplicable 6199; and
in 1850, it's 48,106. It's obvious there is something wrong with
1840 census and that it cannot be complete; and given the low numbers in
the earlier censuses, one wonders how complete they are. The district
entered the Union on 21 Feb 1871 as a municipal corporation. |
