Labour force and changing age structure in selected developed countries: a comparative study

The authors examine the effects of demographic aging and the changing age structure on the labor force in the United States, Canada, and Japan over the period from 1950 to 1980. They find that "the changing age structure and population aging have generally had a favorable effect on the proportion of labour force or crude labour force rate.... The remarkable feature was the rate effect of the female labour force, which was positive and often substantially reinforced the positive age effect.... The proportion of the female labour force soared during the 1960s and 1970s in these countries, and a dramatic convergence of male and female labour force participation rates took place."
