The baby-boom generation is different in some countries because it is defined as those children born to families of servicemen returning home after World War II and for the eighteen years following.
It was decided that in North America this term included people born between 1946 and 1964.
In 2006 there were about seventy-six million baby boomers in the United States and about 9.8 million in Canada.
In that year the boomers began turning sixty, with the youngest, of course, being forty-two.
