Medieval life expectancy: a 13th-century wheel showing the ages of man, by William de Brailes
Facts & Myths

Medieval Life Expectancy: Did Everyone Really Die at 30?

Here’s a “fact” that turns up in pub quizzes, school textbooks and the comments under every history video: in the Middle Ages, everybody was dead by 30. If that were true, medieval Europe would have been run entirely by teenagers, and grandparents would have been about as common as unicorns. So let’s put the claim on trial. What was medieval life expectancy really, where does the famous 30 come from, and how many people actually lived long enough to complain about their knees? Bring a calculator. Don’t worry, the maths is the fun kind.

Medieval life expectancy: the short answer

Yes, average life expectancy at birth in the Middle Ages was low, often around 30. No, that does not mean people typically died at 30.

The low number comes mostly from the huge number of babies and young children who died. Once someone made it through childhood, their chances of reaching their fifties, sixties or even seventies were much better than the headline figure suggests. Old people were not rare curiosities. They were everywhere: running monasteries, ruling cities and, presumably, telling the young that things were better in their day.

Why medieval life expectancy looks so low

Let’s do the maths. Take two medieval villagers. One dies as a baby. The other lives to 70. Their average lifespan? Exactly 35. Neither of them died anywhere near 35.

That is the whole trick behind the myth. Life expectancy at birth is an average across everyone born, including every infant who did not survive. When a large share of children die young, the average collapses, even if plenty of adults go on to live long lives.

Joe Belanger, writing for Sea Lion Press, points to one study by Carrieri and Serraino that put the average lifespan at birth for men in medieval England at just 31.3 years. As he explains, it was high infant mortality that dragged that figure down. Read “31.3” as “an average including a great many babies”, not as “a typical age at death”.

What the skeletons say

Want the real story of medieval life expectancy? Ask the people themselves. Or at least their teeth.

The archaeologist Christine Cave, of the Australian National University, developed a way of estimating age at death from how worn people’s teeth are. She applied it to skeletons from three Anglo-Saxon cemeteries in England, with burials dated between 475 and 625, according to the university’s news release. Smithsonian Magazine reports that several of the people buried there were over 75 when they died.

Why didn’t we know this before? Partly because the old methods were blunt. As Smithsonian explains, researchers usually drop skeletons into three wide boxes: young, middle-aged and older adults, which can lump together everyone over about 40. A 45-year-old and an 85-year-old end up in the same box, and the oldest people quietly disappear from the statistics.

Cave went further. In a news release reposted by Popular Archaeology, she suggests that among people living traditional lives without modern medicine, the age at which people most often die is roughly 70. Not 30. Seventy.

Lords who made it to 70

Written records tell the same story, at least for the people rich enough to leave records.

Statista summarises data on English noblemen who had already reached the age of 21. Between 1200 and 1745, such men could generally expect to live to between 62 and 72. The big exception was the 1300s, when the Black Death dragged adult life expectancy among English noblemen down to just 45.

The economic historian Neil Cummins went bigger still. In a 2017 study in The Journal of Economic History, he worked through the adult death ages of no fewer than 115,650 nobles from all over Europe, spanning a full thousand years, from 800 to 1800. He found that adult lifespans were already rising long before the Industrial Revolution, and that northwest Europe had longer adult lives than the rest of the continent as early as the year 1000.

Of course, nobles ate better and worked less than peasants, so they are not a perfect guide for everyone. But they show clearly that reaching your sixties was entirely normal for an adult who avoided war, plague and bad luck. How those lords and kings fought to keep their lands while they were at it is what the site’s pillar article on medieval kings is all about.

Meet the medieval seniors

Still not convinced? Allow us to introduce some medieval overachievers.

  • Enrico Dandolo was elected Doge of Venice in 1192, aged about 85, according to Britannica. Instead of retiring, he went on to steer the Fourth Crusade towards Constantinople, where he died in 1205. Retirement plans: overrated.
  • Hildegard of Bingen, the German abbess, mystic and composer, was born in 1098 and died in 1179, Britannica records. That makes her around 81, and she spent those years writing visionary books and music that is still performed today.
  • Eleanor of Aquitaine, queen of France and then of England, lived to about 82, according to Britannica. Not bad for someone who survived two royal marriages and a crusade.

Halfway through life at 35

Medieval people even had a standard idea of what a full life looked like. The Bible gave it a number: threescore years and ten, or 70.

The poet Dante used exactly that idea in the first line of his Inferno, which famously opens with the poet halfway through the road of life. As Michael Delahoyde of Washington State University explains, Dante set the poem in 1300, when he was 35: the mathematical midpoint of a 70-year life. A writer who expected to die at 30 would hardly describe 35 as the middle.

The Black Death twist

Here’s a plot twist nobody expects. The worst pandemic of the Middle Ages may have left survivors living longer.

The biological anthropologist Sharon DeWitte, then at the University of South Carolina, studied 597 skeletons from London cemeteries, some from before the Black Death and some from after. Scientific American reports what she found: once the first wave of plague had passed, Londoners of every age were less likely to die than the Londoners buried before the plague. In the centuries before the plague, roughly one person in ten made it beyond 70. Afterwards, the figure was more than one in five.

Why? DeWitte has suggested two possible reasons. The plague may have killed off the frailest people, leaving tougher survivors, and those who were left may have eaten better than before, with more meat, fish and good bread, especially among the poor. There is much more on how the plague reshaped work, food and family over in the big piece about everyday medieval life.

So, was medieval life short or not?

Both, in a way. Medieval life was dangerous. Childhood was a minefield of disease, and adults faced war, epidemics and accidents without modern medicine. A medieval life expectancy at birth of around 30 meant a society that buried a heartbreaking number of children.

But the idea that everyone keeled over at 30 is simply wrong. Skeletons, family records and even poetry show plenty of medieval people living into their sixties, seventies and beyond. So if anyone insists that a 40-year-old in 1300 was ancient, you have every right to raise an eyebrow. It is one more entry in the long list of medieval myths that do not survive a closer look.

Another favourite is the idea that medieval people thought the Earth was flat. They didn’t.

Frequently asked questions

What was the average life expectancy in the Middle Ages?

At birth, often around 30, largely because so many infants and children died. People who survived childhood frequently lived into their fifties, sixties or older.

Did medieval people die at 30?

Most did not. The low average comes from high child mortality. Skeletal studies have found people in early medieval English cemeteries who lived past 75.

How long did medieval nobles live?

English noblemen who reached 21 could generally expect to live to between 62 and 72, except during the Black Death, when adult life expectancy fell sharply.

Did life expectancy change after the Black Death?

Yes. A study of London skeletons found that after the first outbreak, Londoners of all ages died less often, and more than a fifth lived beyond 70, against roughly a tenth before.
