Census Day 1790-1960

Rock County, Wisconsin

 The census day is often misunderstood.
 
The information given to the enumerator (census taker) was to be correct as of the
census day, and census day was not always the same day the enumerator showed up.
 
People who had died between the census day and the day the enumerator came to the house were to be listed as they were alive on the census day. Babies born after the census day were to be omitted as they were not there in the house on census day.
But did our ancestors understand this and give birth and death information correctly?
One can assume errors were made.
