SOC312H1 Lecture Notes - Lecture 4: Baby Boomers, Chart Attack, Population Momentum
Document Summary
Rough approximations for calculating economic dependency burden in aa society. Societies that have a high oadr have a low ydr (ex: japan) Emigration helps balance the low ydr (analyze chart!) Pictoral representation of age and sex composition. Canada"s age pyramid in 2006 (fig 4. 1) Age pyramids: baby boomers, a lot of it comes down to the relative size of the cohorts, echo: cohorts growing through into the next age group. What is stable is the shape of age distribution. Stationary population is a particular kind of stable population (0 growth = constant size) Stable pop model allows us to explore what if scenarios. Like those described in table 4. 3 (different combinations of mortality and fertility. Different populations have different age structures and people do things at different rates and different ages. Stable pop theory allows up to address that by computing what would be the stable pop equivalent. Growing number of elderly in the most densely populated areas.
