For a sizable share of American adults, “till death do us part” was more guideline than promise.

While 52 percent of U.S. adults, 15 or older, have married only once, roughly 1 in 6 (17 percent) have been married twice or more, according a census report released Tuesday. Thirteen percent have been married twice, and 4 percent have been married three or more times.

Here’s a look at some of the report’s key conclusions:

Women are more likely to marry once, twice or three or more times

Among adult men — those 15 or older — 50 percent have been married once, 13 percent married twice and 4 percent married three or more times. Among women, the respective rates are: 55 percent, 14 percent and 4 percent.

Residents of the South and West are most likely to remarry

The married residents of the South and West are more likely to remarry than their counterparts in the Northeast and Midwest.

Among adults 15 years or older who have ever been married, the rates of remarriage range from 16 percent for women in New Jersey to 35 percent for men in Arkansas. In 28 states, larger shares of married men have previously wedded than married women.

Americans are getting married later than ever

The median age of first marriage today — 29 for men and 27 for women — is higher than it has been in more than a century. In 1890, the median age was 26 for men and 22 for women.

Non-Hispanic whites are the most common repeaters by race

Asian men and women are least likely to marry three or more times, while non-Hispanic whites have the highest rates. And that’s true for both men:
