In 1950, after WW2, many families began to have children which meant the birth rate was very high. (1950-1965) -As the baby boomers grow older Canada’s population will continue to age as there is so many of them to still age •What is a centenarian? A person who is 100 years old and above •What does the greying of Canada’s population mean? Population is getting older so it is aging as a whole and not made up of mainly young people o Why is this happening? There are 2 main reasons – can you explain them? INCREASE IN LIFE EXPECTANCY - Life expectancy in Canada is currently 83 years old for men and 84 for women - More Canadians than ever before are living to 85 and beyond DECREASE IN BIRTH RATES - People are not having large families anymore as woman no longer stay home and choose to work, children are expensive and not everyone gets married today o what are some of the problems we can encounter as a country in the future if this continues? More Candians are receiving old age pension and are seeking more health care and services = expensive to have many seniors Proportionally fewer people are working and paying income tax = less money available Housing and transportation needs are changing, as is consumption, which is shifting towards goods and services for seniors The # of families made up of couples whose children have left home is also on the rise •Where does the majority of Canada’s population live?
