The average number of children born per woman in the United States is 1.73. This number has been declining steadily for decades, and is now at its lowest level since the early 1900s. There are a number of reasons for this decline, including the increasing cost of raising children, the desire for women to have more education and career opportunities, and the increasing availability of contraception.
Ultimately, the number of babies a woman has is a personal decision that should be made in consultation with her healthcare provider.
