The Atlantic Region has experienced considerable demographic growth in recent decades.
Nevertheless, its percentage of the Canadian population has declined continuously during the past half-century, and further declines seem likely. In large measure that can be attributed to the fact that the region, and each province in it, receives disproportionately small shares of immigrants to Canada.
Like the rest of the country, the Atlantic Provinces experienced the postwar baby boom, and the subsequent bust. In consequence their populations are now aging, in a collective sense. In just over a decade the first of the baby boomers will be “old”, by conventional definition, and the percentage of population 65 and over will rise continuously in the coming decades.
