Where were most babies born 1,000 years ago?
Read these as orders of magnitude. No source records births anywhere in the world in the year 1000. These figures come from HYDE's reconstruction of where people lived, combined with a birth rate modelled from mortality and population growth, and they are uncertain by roughly a third either way. The country names are labels for areas inside today's borders — there was no "India" or "Mexico" in the year 1000 in anything like the sense the table implies.
The ten areas with the most births, year 1000
| # | Area (modern country) | Estimated births | Share of world |
|---|---|---|---|
| 1 | India | ~4.54M | 34.3% |
| 2 | China | ~1.62M | 12.3% |
| 3 | Mexico | ~613K | 4.6% |
| 4 | Brazil | ~461K | 3.5% |
| 5 | Bangladesh | ~301K | 2.3% |
| 6 | Nigeria | ~288K | 2.2% |
| 7 | Türkiye | ~282K | 2.1% |
| 8 | France | ~268K | 2.0% |
A different world, and a familiar one
The continental picture in the year 1000 is recognisable: Asia 65%, Europe 11%, Africa 12%, the Americas 11%. Asia led then and leads now. What has changed is the scale and the rate: about ~13.24 million births a year then against 132.4 million today, from a world population roughly 25 times larger.
The birth rate, though, was far higher — around 41 births per 1,000 people a year, against 16 today. In a world where life expectancy at birth was somewhere near 25 years, a society needed roughly that many births simply to replace the people it was losing. High birth rates and a barely growing population are the same fact seen from two sides.
Why the pre-modern map looks flat
Colour the map by births in the year 1000 and most countries land in neighbouring shades. That is not a rendering problem — it is the evidence. Before the demographic transition, birth rates varied far less between societies than they do now, because they were held near the level mortality demanded. Almost all the variation in how many babies were born somewhere was variation in how many people lived there. The modern map, where 16 per 1,000 is an average spanning everything from under 5 to over 45, is the historical anomaly.
