How long did people really live in the Middle Ages?
Medieval life expectancy at birth is often quoted at around 30, which is sometimes read as people dying of old age in their thirties. Skeletons, noble genealogies, monastic records and model life tables show what that average does and does not mean.

In medieval England, life expectancy at birth for boys of landowning families was 31.3 years, while landowners who reached 25 could expect on average to live to 50.7.▰▰▰▱▱ likely2 points
Supports- In medieval England, life expectancy at birth for boys born to families that owned land was a mere 31.3 years. However, life expectancy at age 25 for landowners in medieval England was 25.7. This means that people in that era who celebrated their 25th birthday could expect to live until they were 50.7, on averageSharon DeWitte, Misperceiving Life Expectancy in the Deep Past, SAPIENS analysis
- Medieval demography involves complex reconstruction, as the earliest systematic records of births and deaths date to the 16th century, but estimates for life expectancy at age 25 based on sources such as tenancy records range from 20 to 25 years (Jonker, 2003; Razi, 1980).John Robb, Craig Cessford, Jenna Dittmar, Sarah A.

Medieval demography involves complex reconstruction because the earliest systematic records of births and deaths date to the 16th century; in 1538 Thomas Cromwell ordered churches in England and Wales to keep registers of births, deaths and marriages.▰▰▰▱▱ likely3 points

Supports- Now if you remember how averages work, you will realise that if half the population are dying before they are two, and the average age of death is 35, that means that if you made it out of infancy (a pretty big if, TBH), you were likely to make it into your seventies or even later.Eleanor Janega, On the myth of short life expectancy, and COVID complacency, Going Medieval (2021) analysis

A belief holds that average life expectancy in the medieval period was 35, so that someone aged 32 was considered old.Refuted by
Given physical and historical evidence that many people did live long lives in the past, why does the misperception that everyone was dead by the age of 30 or 40 persist? It stems from confusion about the difference between individual life spans and life expectancy.
