Between 1935 and 1957, a period that included World War II, the birth rate rose from 16.9 to 25 per 1000 people. What was the most likely cause of this "baby boom?"
The birth rate where? US? Canada? England? Where??
Your numbers appear to be for the United States.
The standard of living was low in 1935, and many people had no jobs or homes. Raising a family was a luxury then. Many chose to defer childbearing and have smaller families.
Why the birth rate began to fall after 1957 is harder to explain. It remains low at present compared to the 1935-1957 era. People's attitudeas to having large families has changed. More women have to work, and many people choose to spend more money on fewer children, or on other things.
The increasingly wide acceptance and use of "the pill" for birth control after about 1960 probably had a lot to do with lowering of the birth rate in later years. There were also overturned laws prohibiting birth control devices in Massachusetts and Connecticut at about that time.
