The Marriage Market at Age 35

Increasingly, a bachelor's degree is a prerequisite for marriage. The latest data from the National Longitudinal Survey of Youth 1997 (NLSY) provides further evidence of this fact. The NLSY has been tracking a nationally representative sample of men and women born during the years 1980 through 1984. Respondents were aged 12 to 17 the first time they were interviewed in 1997. In the latest (19th!) survey, fielded in 2019–20, respondents were aged 34 to 40. 

At age 25, there were few differences in marital status by educational attainment among the NLSY respondents, with just 27 percent of them married. By age 35, big differences by educational attainment had emerged. Overall, 53 percent of the NLSY respondents were married at age 35. But the married share ranged from a low of 37 percent among the high school dropouts to a high of 65 percent among those with a bachelor's degree or more education.

Partner status at age 35 among people born 1980–84 by educational attainment

	Married	Cohabiting	Single
Total people	53%	17	31
Less than high school diploma	37%	25	38
High school grad, no college	43%	23	34
Some college/associate's degree	50%	16	34
Bachelor's degree or more	65%	11	24

What accounts for these differences in marital status by educational attainment? The Marriage Market. The better educated are more likely to be married because their earnings are higher and their jobs more secure, making them more attractive marriage partners.

Death Rate Much Lower for Married People

Married people have strikingly lower death rate than the never-married, divorced, or widowed, according to a report by the National Center for Health Statistics. Take a look at the number of deaths per 100,000 population in 2017 by marital status...

Age-adjusted death rate by marital status in 2017
   779.6 for the married
1,368.8 for the divorced
1,443.6 for the never married
1,656.9 for the widowed

The age-adjusted death rate of married people was 43 percent lower than the death rate of the divorced in 2017. It was 46 percent lower than the death rate of the never married, and 53 percent lower than the death rate of the widowed.

One factor that leads to the lower death rate for the married is self-selection, with healthier people more likely than the less healthy to be married. Another factor is the benefit of living with someone who has your back, urging you to go to doctor appointments, take your pills, and eat right. A third factor leading to higher death rates for the single, divorced, widowed, is the stress surrounding the single life, marital breakups, and the death of a spouse.

Partner Status at Age 29

Young adults have been postponing marriage. The latest results from the National Longitudinal Survey of Youth 1997 are more evidence of this trend. The NLSY 1997 is tracking a nationally representative sample of men and women born from 1980 through 1984 and first interviewed in 1997. The latest results, which examine educational attainment, labor force experience, and partner status, are from the 16th interview of the sample and took place in 2013-14. On their 29th birthday, fewer than half of young adults were married, one in five was cohabiting, and among men the plurality was single...
