Step 1 : Introduction to the question "At what average age do American women become first-time mothers?"
...Women are becoming mothers later in life. According to the National Center for Health Statistics, the average age of American women at the time of their first birth is 26.3. The increase in the average age to have a baby reflects two broader trends: women getting married later in life and more women attending college. The average age at which women tie the knot for the first time is 27.6 years, rising to 29.5 years for men. That's a sharp jump from the average marriage ages of 21 and 23 reported in 1968.
