U.S. enumerators were supposed to record the household’s information as of the official census day — not the actual date of the enumeration. But we have no way of knowing who followed these instructions and who did not. The official census days were:
First Monday in August for 1790-1820 schedules
June 1st for 1830-1880
First Monday in June for 1890 (most of this census was destroyed or badly damaged by a fire in 1921)
June 1st for 1900
April 15th for 1910
January 1st for 1920
April 1st for 1930 & 1940
Census Records in the NCGenWeb Archives
The 1890 census was almost totally destroyed by fire in Washington DC.
The Cabarrus 1890 Tax Roll does exist, and microfilm and a partial transcription are available at the Cabarrus County Library in Concord.
