Requesting data underlying Historical Age Pyramid

Question

A student here would like to be able to use the statistics underlying the historical age pyramid at https://www12.statcan.gc.ca/census-recensement/2011/dp-pd/pyramid-pyramide/his/index-eng.cfm. Specifically, he would like to have population by single years of age by gender for each year (1921 through 2011).

I found Age Groups (13) and Sex (3) for the population of Canada, Provinces and Territories, 1921 to 2011 Census (http://www12.statcan.gc.ca/census-recensement/2011/dp-pd/tbt-tt/Rp-eng.cfm?LANG=E&APATH=3&DETAIL=0&DIM=0&FL=A&FREE=0&GC=0&GID=0&GK=0&GRP=1&PID=102186&PRID=0&PTYPE=101955&S=0&SHOWALL=0&SUB=0&Temporal=2011&THEME=88&VID=0&VNAMEE=&VNAMEF=), but suspect that he wants the individual years of age rather age groups.

Are these time series available, or would requesting them require a special tabulation?

Answer

I have been unable to find the time series for individual years dating back to 1921. These series seem to be available for age groups.

For individual years I found online:

Topic-based tabulation: Age (131) and Sex (3) for the Population of Canada, Provinces, Territories, Census Metropolitan Areas and Census Agglomerations, 2006 and 2011 Censuses

98-311-XCB2011021

Age (123) and Sex (3) for Population, for Canada, Provinces, Territories, Census Metropolitan Areas and Census Agglomerations, 1996 and 2001 Censuses - 100% Data - Cat. No. 97F0003XCB2001001.

Others for age for 2001 census

If they were to obtain a custom tabulation from the Regional offices, they would however only be able to get tables as far back as 1971.

Median ages in Newfoundland

Question

I'm trying to find median age (or data that can be used to calculate median age) by census division for Newfoundland, for the 1991 & 1996 censuses. Any suggestions?

Answer

I could not find a simple answer for you and therefore I asked the division for help. Following is their response:

There are no standard products available for 1996 and 1991 which include median age at the CD level. I have explored the possibility of using data to calculate the median age but have been advised that this is not an option, as the data that is produced has been rounded and the results would not be accurate. In order to produce median age, the person would have to be working with unrounded data and single years of age, and as you are aware we do not release unrounded data due to confidentiality
issues. The only other option available would be produce custom tabulations at a fee to the client.
