For Allyson Jacobs, life in her 20s and 30s was about focusing on her career in health care and enjoying the social scene in New York City. It wasn't until she turned 40 that she and her husband started trying to have children. They had a son when she was 42.
Over the past three decades, that has become increasingly common in the U.S., as birthrates have declined for women in their 20s and jumped for women in their late 30s and early 40s, according to a new report from the U.S. Census Bureau. The trend has pushed the median age of U.S. women giving birth from 27 to 30, the highest on record.
