Document Summary

A population becomes old when it contains a large proportion of elderly people: in 2006, 13. 7% of canada"s population was 65+ Mortality, fertility and migration internally and externally change the size and compositions of populations. When at least 10% of the population is over 65 it is considered old. Median age in canada is 39. 5 years. Aged dependency ratio: number of persons 65+ divided by the number of people between 20-64 (those working to support the dependent population) Youth dependency ratio: number of individuals 0-19 divided by the number of individuals 20-64. Total dependency ratio: number of individuals 0-19 plus those 65+ divided by the number of individuals 20-64.

Population pyramids show the distribution of people in a population by age.
