How far the world's people went in school
- 15 of 100adults never went to school (2020)
- 44 of 100adults finished upper secondary or went further
- 2070the world’s people aged 15 to 64 are most numerous (projected)
- 2090the ones among them who finished upper secondary are most numerous
If the world's adults were 100 people, 15 of them never went to school, and 44 finished upper secondary school or went further. That was in 2020, when the Wittgenstein Centre counted 4.58 billion people aged 25 and over. If schooling keeps spreading at the pace it has, by 2050 it would be 8 and 64.

How to read this: each block is the world's adults (25 and over) shrunk to 100 people, one square each, coloured by how far that person went in school: the stronger the colour, the more schooling. The numbers in the list are 2020's. The 2050 block is striped because it is a projection, not a count. projected

In plain words
What is it?
This page is about how far people went in school: the highest level each person finished. It counts adults, because most people have left school by the age of 25.
The numbers come from the Wittgenstein Centre, which counts the world's people by age, sex and schooling in 2020 and projects them forward to 2100. Its middle projection is the page's line.
Schooling is finished young and kept for life, so a country's adults change slowly, one generation at a time. That is why the page keeps comparing the young with the old.
Why it matters to you
- Your generation. Of every 100 women aged 25–29, 11.4 never went to school; aged 60–64, 21.5.
- Work. People of working age peak in 2070, but those who finished upper secondary keep growing until 2090.
- Where it is hardest. In Niger, 74.9 of every 100 adults never went to school.
- Numbers, not just shares. The most adults who never went to school live in India: 260.4 million.
Adults by age · 2020
Each generation went further
Schooling spreads one generation at a time. Of every 100 people aged 25–29 in 2020, 10 never went to school; of every 100 aged 85+, 25. Among women the change is larger: 11.4 of every 100 women aged 25–29 never went to school, against 21.5 of every 100 aged 60–64. For men it is 7.7 against 12.9.

How to read this: one row for each five-year age group in 2020, youngest at the top. Each row is 100 people of that age, coloured by how far they went in school. Reading down the rows is going back in time: the oldest rows went to school sixty years before the youngest.

Fewer workers, with more schooling
The world's working-age people, 15 to 64, are projected to be most numerous in 2070, at 6.19 billion. The ones among them who finished upper secondary school keep growing for another 20 years, to 2090: from 2.35 billion in 2020 to 4.76 billion. Fewer workers, and more of them with more schooling.

How to read this: one column for every fifth year, 2020 to 2100. Each column is all the world's people aged 15 to 64 that year, stacked by how far they went in school, least schooling at the bottom. Only the 2020 column is counted; the striped ones are the Wittgenstein Centre's middle projection. projected
If schooling spreads faster, or stalls
The projection rests on how fast schooling spreads. The Wittgenstein Centre also works out two other futures. They are not a range around the middle one: they are what would happen if the world took another road.
| Future | What changes | People 15–64 | Those who finished upper secondary |
|---|---|---|---|
| Middle of the road | schooling keeps spreading at the pace it has | most in 2070 | most in 2090 |
| Faster | schooling spreads faster and families are smaller | most in 2045 | most in 2065 |
| Stalled | schooling stops spreading and families stay larger | still rising in 2100 | still rising in 2100 |
The working-age page gives the UN's own peak year for the world's people aged 15 to 64. The two are counted separately and are never mixed on this site.

Girls and boys
Where schooling came late, it came to boys first. In Africa, 59.3 of every 100 women aged 60–64 never went to school, against 38.1 of every 100 men. Among 25- to 29-year-olds it is 25.5 and 17.6: fewer on both sides, and a smaller gap, but not none.

How to read this: each bar is how many of every 100 women, or men, of that age never went to school (2020). The number is at the end of the bar; women are amber, men violet, and every bar is labelled. The Wittgenstein Centre gives North America no area of its own, so it is not drawn here; the United States and Canada are in the table below.

Where the fewest went to school
In Niger, 74.9 of every 100 adults never went to school, the highest share of any country with a million adults or more. The largest number is in India: 260.4 million adults, 33.8 of every 100 there.

How to read this: "of 100" means of every 100 adults aged 25 and over. 2050 and the peak years are the middle projection. "2020 or before" means the number was already falling when the count begins; "after 2100" means it is still rising at the end.
Limits
What this page cannot show
- Years in school, not what was learned. These are the levels people finished. Two people with the same years can read very differently. The share of adults who cannot read is a different measure, from UNESCO, on how the world's people live.
- No years before 2020. This version of the Wittgenstein Centre's work starts from 2020. Its earlier reconstruction back to 1950 used another base year and other countries, so the two are not joined.
- No figure for 36 places. The Wittgenstein Centre does not count American Samoa, Andorra, Anguilla, Bermuda, Bonaire, Sint Eustatius and Saba, British Virgin Islands, Cayman Islands, Cook Islands, Dominica, Falkland Islands, Faroe Islands, Gibraltar, Greenland, Guernsey, Isle of Man, Jersey, Kosovo, Liechtenstein, Marshall Islands, Monaco, Montserrat, Nauru, Niue, Northern Mariana Islands, Palau, Saint Barthélemy, Saint Helena, Saint Kitts and Nevis, Saint Martin, Saint Pierre and Miquelon, San Marino, Sint Maarten, Tokelau, Turks and Caicos Islands, Tuvalu and Wallis and Futuna.
- No average years of schooling. The Centre publishes a file under that name, but its numbers run from 0 to about 2, so they are not years; until what it holds is clear, this site does not use it.
Back to the count
How this rests on the census
The adults this page counts are everyone aged 25 and over. In mid-2025 that was 4.94 billion people, 60 of every 100 of every 100 alive (the UN's count, drawn here only to show which ages the page is about).
adults aged 25 and over everyone else
How to read this: one column for each year of age, from newborn babies on the left to people aged 100 and over on the right. The taller the column, the more people of that age were alive in mid-2025 — 8.23 billion in all, counted by the UN.
The children and teenagers below 25 are not in these shares: many are still in school, and where they stop is what will change the next generation's figures.
Questions
Questions people ask
How many adults in the world never went to school?
15 of every 100 adults aged 25 and over in 2020, by the Wittgenstein Centre's count. By 2050 it is projected to be 8.
Is the world’s workforce getting more educated?
Yes. The world’s people aged 15 to 64 are projected to be most numerous in 2070, but the ones who finished upper secondary school keep growing until 2090.
How many adults finished upper secondary school?
44 of every 100 adults finished upper secondary or went further in 2020; by 2050 it is projected to be 64.
Where do the most adults who never went to school live?
In India: 260.4 million adults. The highest share is in Niger, 74.9 of every 100.
Where do the numbers come from?

Apparatus
Sources and method
Method: every number on this page is the Wittgenstein Centre's own count of people by age, sex and the highest level of school they finished, on 1 January of every fifth year, 2020 to 2100. 2020 is built from censuses and surveys; every later year is a projection. The middle projection (the Centre's SSP2) is the page's line; the faster (SSP1) and stalled (SSP3) futures are shown only in the table of peak years. Adults are 25 and over, because most people have finished school by then. "Of every 100" shares are whole numbers that add up to exactly 100. The Centre's population is its own projection, so it is never set beside the UN's count used elsewhere on this site. Version WIC3.005 (internal V15), doi 10.5281/zenodo.20447835, fetched 2026-09-29. The same projections can be explored on the Centre's own Human Capital Data Explorer.
