When Did Teen Girls Stop Commonly Getting Married?

Jamie M asks: When did having young teenage girls marry stop being so widespread?

married-kidsA long, long time ago.

Marriage in the Ancient World

In the Western world (and generally speaking) before imperial Rome, girls were deemed sufficiently mature for marriage and sex when they first started menstruation (and boys, by the way, when they developed pubic hair). Marriage was relatively unregulated by the state then, and instead was seen as a private family matter, so it is presumed these boundaries were flexible.

The Roman emperors began to take matters in hand beginning with Caesar Augustus’ marriage laws (18 BC and 9 AD):

He ordered that no betrothal should be valid if the man did not marry within two years of such betrothal . . . [and] that the girl must in every case be at least ten years old at her betrothal . . . . girls are held to have reached the marriageable age on the completion of twelve full years.

By the end of the empire, the age of consent for girls had been well settled, as the “official” age of reaching puberty was set at 12.

Medieval Marriage

The Catholic Church had rules for just about everything during the Middle Ages, and one of its most authoritative texts was the Decretum Gratiani. Written by the jurist Johannes Gratian in the 12th century, it set a minimum age for betrothal (not necessarily marriage) at seven years for boys and girls, and the lawful age for a woman to consent to marriage (and “carnal intercourse”) at twelve, although certain unusual circumstances would render marriages at younger ages valid, as well.

Gratian was followed by others including Hostiensis (Henricus de Seguisio) who opined that a young woman’s physical development, not her age, should determine whether she was ready for marriage.

Recent scholarship indicates that although medieval marriages could occur at ages as young as 12, that might not have been the norm:

While marriages at very young ages could and sometimes did take place, particularly for girls of high social status, it would be a mistake to see marriage below or around the age of puberty as the norm even for young noblewomen. . . . Emerging evidence is eroding the stereotype . . . [with] work on low- and lower-middle-status women [showing that] . . . a large proportion of the sample married between the ages of eighteen and twenty-two, [and] . . . showing that urban girls [in Yorkshire] tended to marry in their early to mid-twenties and rural girls . . . in their late teens to early twenties.

Marriage in Early America

A study performed by the National Bureau of Economic Research (NBER) on marriage in North America and Western Europe mirrors the findings of the Yorkshire researchers; the NBER found that young women from the 17th through 19th centuries were not all that young when they got married.

For example, in Massachusetts records dating from 1652 to 1800 demonstrate that the mean age of first marriage for ladies was between 19.5 and 22.5 years, and records for other colonies reflect similar ages. In fact, the average age of first marriage for all of the colonies studied was 19.8 before 1700, 21.2 during the early 18th century, and 22.7 during the late 18th century.

This is consistent with data gathered in England, France and Germany that puts the average mean age of first marriage for women at 25.1 from 1750-1799 and 25.7 from 1800-1849.

Marriage Post Civil War

Maintaining the trend, by the end of the 19th century, the median age when women were first getting married was between 22 and 24 years old, and this tendency continued into the 1940s.

In fact, the lowest median age of first marriage since the early 1700s was had by the baby boom generation, where the age dropped to 20.5 years in 1950.

Marriage Age Today

As of 2010, the median age of first marriage for women was 26.1 (28.2 for men), although research demonstrates that “marriage is most often delayed rather than foregone,” and although they may wait awhile, “more than 90 percent of women will eventually marry.”

Researchers note that the median age in 2010 was 3.4 years higher than in 1900, and opine that this “likely reflects the change in women’s status in society – as women are pursing education and careers before marriage . . . they are increasingly delaying the age at which they marry.”

Bonus Facts:

  • A little over 2,000,000 marriages happen in the U.S. each year, or about 6.8 marriages per 1,000. The divorce rate is typically around 3.6 per 1,000 per year.
  • According to a recent CDC study of first marriages and cohabitation, between 2006 and 2010, the number of women in a first marriage declined by 8% while those in a cohabiting relationship increased by 8%.
  • While you’ll often read that there is a 50%-52% chance of any given marriage ending in divorce, this isn’t quite accurate, or at least doesn’t tell the whole story. It only looks at the raw figures of marriages each year vs. the number of divorces.  This doesn’t take into account repeat divorcees, which skew the totals in any given year. In fact, 67% of second marriages and 73% of third marriages end in divorce.  The average divorce rate for first marriages is only about 41% in the United States, and these divorce rate figures have been declining significantly in the last few decades.
  • Marriages where both partners have a college degree only end in divorce about 25% of the time.

  • Interesting article but I think you have something wrong. You state, “…In fact, the lowest median age of first marriage since the early 1700s was had by the baby boom generation, where the age dropped to 20.5 years in 1950.” If they are 20 years old in 1950 they were born in 1930 and are more than a decade away from qualifying as a baby boomer (born between 1946 & 1964).

  • um… I would like to point out, for some reason you focus on “Western” Civilization, which is odd. It doesn’t give any indication of this in the title of the article, and I expected a worldwide look. Obviously you can’t claim lack of information given oral tradition that has been written down and can be found (despite less evidence) and multiple other cultures who did keep records on this. Otherwise, good article.

  • And doesn’t the mean age get all messed up when people over 40 get married too?

  • This is a US centric site but there was more to the “New World” than the 13 colonies. New France existed. In what is now Quebec, there was a lineup of men waiting for each female child to turn 12 years of age as that was the legal age she could be married.

  • Makes more sense to marry when older… you see, men were supposed to provide for the spouses and no 12 yo boy has the experience or means for that.

    • Yuneek The Infamous

      This depends on the society. Societies where boys marry girls (as opposed to men marrying girls or women) typically the newlyweds remain a part of the husband’s family’s household for a period. In general, this arrangement means the newlyweds are far less independent of the husband’s family compared to ones where the husband is older and better established.

  • Since I am “old” I can say I knew a few women that had been married age 14 and 15 and 17. They were nurses I had worked with and one of my neighbors at 15 with her mothers consent. My Mom had told me it was very common for teenagers to be married in 1800’s and early turn of century society. I had gone thru a period of time feeling a lot of anger and lack of understanding about my church. I continued reading anti mormon articles thinking I was getting the scoop from those that had lived it and felt disallusioned Then I realized at one point maybe I should study from gospel books to see if i could find an understanding for what I had been getting influenced by. I gave a lot of time to both of subject. To my surprise I found myself feeling peace and gaining understanding that I hadn’t had before. I Am so sorry that you have been so hurt from a gospel that the Saviour Himself wants to be of love and understanding. A few weeks ago you posted a statement from a church leader on Unwed mothers having babies. I was heartsick. Could you let me know who that was again. I need to investigate who and why they would say such a thing. In my whole life I have been taught at church EVERY child is a blessing and sent from God. If I see that that statement was not out of context or whatever I will personally send a letter of requesting explanation to President Nelson. I love you Precious Jennica!
