In column 10 of Form 1A and Form 1B, the population schedules excluding the North West Territories, of the Seventh Census of Canada, 1931, we find an interesting question being asked:
" Has this family a radio? "
This was the first and only time this question was asked in a census of Canada. Interestingly, this question was also asked in the Fifteenth Census of the United States, 1930 where in the "Home Data" section they asked "Radio set" in column 9.
