“In 1800, the American birthrate was higher than the birthrate in any European nation. The typical American woman bore an average of 7 children. She had her first child around the age of 23 and proceeded to bear children at two-year intervals until her early 40s.”

That information matches up with generations of my own family, as well as most families in our community. Through the first half of the 20th century, the women continued to have babies from their early 20's to their 40's.
