Canadian Census

Most people use a Canadian Census at some point when researching their family tree. We sometimes use the age on a census to take a guess at a family members birth date. Or, just to try to confirm that the age of the person is in the range we are looking for to confirm a family member. Occasionally we look at the age given for a family member and then check the next census 10 years later, only to find there is 11 years, or 9 years, difference in the age of the person. Why is this? Was the census taken before, or after, the person's birthday? 

Jean Lawson has supplied some information to help solve these mysteries. We have added a few other dates obtained from the National Archives web page on Census Records.

The dates traditionally given below for each census is the "official enumeration date". The actual enumeration could have taken weeks or months to complete. However, enumerators were instructed to record the information on the census returns as it existed on the official enumeration date.

1825 Census
The 1825 Census of Lower Canada (Quebec) was taken from June 20 to September 20, 1825.

1851 Census
The 1851 Census was taken January 12, 1852. The age given on the census is the age for the NEXT BIRTHDAY (1852), not the age of the person in 1851. There are columns for deaths during 1851, cause of death, male or female. An Agricultural Census is available for some sections.

1861 Census
The 1861Census was taken January 14, 1861. The age given is the age on their next birthday. Check the whole county in the Agricultural Census, as some of the pages are out of order.
