baby boomlet

The baby boomlet was a period marked by increases in the number of women of childbearing age and increases in fertility rates of those women.

Over a long-term period, population growth would be affected by changing birth rates due to shifts in social values and movement of age cohorts such as baby-boomers and baby-boomlets through the child-bearing years.

Following the Second World War there were "baby boomlets" in Europe, but these lasted for only a year or two, unlike the prolonged birth rise in New Zealand, Australia, Canada, and the United States.
