Born Then

Life in the 13th century

Be born somewhere between 1200 and 1299, weighted by real births, and live five lives from that year on.

The numbers

The world had about 389 million people around the middle of the 13th century. Life expectancy at birth was near 25 years, mostly because so many children died; people who reached adulthood often lived into their fifties or sixties. About 5% could read and 9% lived in towns. Most births happened in South China (16%), North India (14%), South India and Sri Lanka (8%), North China (7%), Central Europe (5%).

All numbers before 1800 are modelled from long-run population and life-expectancy estimates by region. How it works
