One of our biologists is looking at birds and needs to map population density at the EA level from 1981 to 2001. He (and I) can only find CSD-level data for 1981. Do these data exist? I've checked the DLI ftp site and can't find anything below CSD for 1981.
It turns out that Statistics Canada never produced EA boundary files for the 1981 Census and the land area is not available for your researcher to calculate the population density.
