Starting in 1850, the U.S. census had a date at the top of the page for when the enumeration was recorded for the families on that page. I was looking at the 1830 census and 1840 census in Claiborne, Louisiana in particular and see on Wikipedia that those censuses were recorded as of June 1, 1830 and June 1, 1840.
For the family I'm interested in, I looked at the first page and last page of the section, hoping there might be a date there, but none were found. Where might I find clues as to a more precise date the family was enumerated?
I know that 1850 census was also conducted on June 1, 1850, but have seen pages dated September. Was the census taker supposed to enumerate as of June 1st and ignore any births since then and give ages as of June 1st? If so, how well did they typically follow these directions in the 1830 and 1840 censuses?
