average age to have children
The average age of women having their first child was a record high of 26 years old in 2013, according to the Centers for Disease Control and Prevention's National Vital Statistics Report. That's an increase of 3.3 years since 1980, when the average age was 22.7. Most of the change took place between 1980 and 2000, when the average rose to 24.9. It stayed relatively stable around 25 until 2008, when it started climbing again to its current high: Business Insider / data from CDC.
