Another reason not to create census categories for Canada.
The 1871, 1881, 1891 and 1901 censuses were used for two purposes, counting the population and creating a voters list, this is why the name of the electoral district is on the 1871, 1881, 1891 and 1901 censuses. The electoral district names were not the names of the places where people lived.
As one example Cardwell was the electoral district that included the village of Alton, in Caledon Township, Peel County, Ontario, Canada from 1867 to 1904. It was not the name of a place or town or village in the area.
Ancestry and some other census transcriptions have used the name of the electoral district on the census.
This creates significant problems when people look for records for a place named Cardwell, and sometimes depending on the name of the electoral district, they find a place with that name. There is a Cardwell Township approx. 230 km north of Alton. The place has has nothing to do with the village of Alton, the town of Caledon, or the town of Caledon East or the Township of Caledon.
The names of electoral districts change often, and the electoral districts cross county, township and municipality lines. I have lived in the same house for 31 years, the name of the electoral district has changed 4 times in that time. The name of the place has been the same since 1974.
Even contemplating this idea is a 'nightmare waiting to happen'.
