Document Summary

Population size and structure are affected by the following three demographic forces: fertility rate. *fertility rate has gone down, explaining why we have not had a replacement for our population explains why such a large portion of our population is older. The greatest changes in the canadian population are due to: Baby boom sharp rise in the fertility rate in canada from about 1946-1964. Baby bust sharp drop in the fertility rate from the mid-1960s on. Alters the ethnic make up of canadian society and older canadians. Oversimplified notion that a demographic trend such as population aging has devastating consequences for society. Goal is to provide a conceptual image of how population"s age-sex structure looks. Two bar graphs laid back to back. Males and females are on opposite sides. Each bar represents the number of people age and sex in the population. Some people say it will be a drain on pensions that the young working people have to support.
