Patterns and change in Canadian fertility 1971-1988: first births after age 30.
An analysis of Canada's changing pattern of births during the period 1971-1988 suggests that the tempo and timing of fertility has changed. Between 1971 and 1988, the number and rates of first births to women in their 30s increased rapidly, and rates for women younger than 25 declined. The rate of first births (first births per 1,000 women) for women 30-34 increased from 11.5 in 1971 to 17.1 in 1981 and to 22.3 in 1988--a 94% increase over the 17 years. The rate for women 35-39 also rose from 3.0 in 1971 to 3.6 in 1981 and 5.9 in 1988--a 97% increase occurring mostly in the 1980s.
