INSIDER Data analyzed US Census Bureau data and found that the average age of men and women at their first marriage has increased over time.
In 1940, the average age of men at their first marriage was 24.3, and the average age of women was 21.5. From 1950 until the late 1970s, the average ages of men and women dipped to 23 and 20, respectively. But since the 1980s, the average ages of first weddings have been increasing. For men, the average age has climbed from 25 in the late ’80s to 29.8 in 2018. For women, the average age went from 23 to 27.8.
According to a 2016 Gallup poll, 20% of Americans ages 18 to 30 are married, compared to 32% of Gen X-ers and 40% of baby boomers when they were the same age.
