Question:
I have a researcher looking for data surrounding workplace pension plans pre-WW2 and during WW2. He’s also interested in the gender share of workers in different industries and the gender share of new workers by industry, particularly during the Great Depression and WW2.
Does anyone have any suggestions?
Answer:
... have you had a look at the Historical Statistics of Canada (2nd ed.)?
That link takes you to Section D on the Labour Force that includes a set of tables which might address part of your question ("gender share of workers in different industries"). They can be downloaded in CSV format.
Table D8-85
Work force, by industrial category and sex, census years, 1911 to 1971 (gainfully occupied 1911 to 1941, labour force 1951 to 1971)
Your researcher will want to read the accompanying notes on the site.
