A lot of people get married. And if things work out, they'll stay happily married and go on to celebrate many more Valentine's Days together.
But things don't always work out.
Using individual-level Census data from the Minnesota Population Center's Integrated Public Microdata Sample project, we took a closer look at different marital outcomes by each year of age in 2013, the latest year for which data is available.
Based on responses to questions about marital status and number of marriages, we found the proportion of the population at each age that had never married, was in its first marriage, was widowed, or was in a situation in which its first marriage had ended. That last group combines people who responded that they were divorced, separated from their spouse, or in a second, third, or later marriage.
In 2015, about 11% of 30-year-olds had already ended one marriage. The proportion of people who were divorced, separated, or married multiple times maxed out at age 63 when about 42% of respondents fell into this category. That was just shy of the 43% of 63-year-olds who were in their first marriage:
We also compared the 2015 proportions of people who were divorced, separated, or married multiple times to those proportions from earlier decades. The 1960 and 1980 Census long form survey, the predecessor of the American Community Survey, also included questions about marital status and number of marriages.
The results were interesting: In 1960 and 1980, a higher proportion of 20-somethings had a marriage end than in 2015. Much more people were in second or third marriages by their late 20s in 1960 and 1980 than in 2015.
On the other hand, older Americans have been more likely to fall in this category in recent years: In 2015, respondents over 40 were far more likely to be divorced, separated, or in a later marriage than people of an equivalent age in earlier decades:
