For 100 years, Census Day has been April 1.

For the 2010 census, a new section was added to the Overview page, Key
2010 Census Dates. The other years don't have this, but at least I
know that for 2010
"April 1, 2010 - Census Day. Households are asked to supply data in
their census questionnaire that is accurate as of April 1.
April 30, 2010 - Enumerators begin door-to-door operations to collect
census data from households to follow up with households that either
didn't mail back their form or didn't receive one.
July 30, 2010 - The toll-free telephone assistance line is closed,
ending 2010 census data collection. More than 130,000 interviews were
completed via the toll-free line."
So that's 3 complete months, during which time there were doorknockers .
Does anyone know how long it was this year. It prob
Not clear from that enumerators were out there for the three full months.
This year from what I can tell it was two months, maybe a little less,
starting in early August, ending early Oct. It probably varied a bit by
region of the country. But the real issue here is what percentage was
completed this year versus previous years and if it's substantially
different, does it make any difference in the result. They will never get
to 100%, there will always be a few percent left. That is then filled in
using estimates and models based on the 97% or whatever they have. So
if one year they get to 98%, while another year they get to 96%, not clear
that it really matters. At some point, people that refuse to cooperate
or where contact can't be made, where somone can't be found to provide the
data, another month of pounding on the door isn't going to change the result.
As to the completion date, I read under Herman Hollerith that the 1880
census counting was completed in 1887. So there is no need to be done
by January 2021.
Census day in every year back to 1930 was April 1
In 1920 it was Jan 1, of all things.
In 1910 it was April 15
In 1900 it iwas June 1
The url above goes back to 1790 but I don't have time to read everything
now.
