Question

What was the precursor to the baby boom?

Answer 1

WWII was the precursor to the Baby Boom.

The term "Baby Boom" most often refers to the post–World War II Baby Boom (1946–1964) when the number of annual births exceeded 2 per 100 women (or approximately 1% of the total population size). There are an estimated 78.3 million Americans who were born during this period.
