Humanity speaks about 7,160 languages. Most are spoken by very few people — and nearly half are now endangered, with the pace of loss set to quicken.

01 · The lopsided ledger
Twenty-three languages carry half of humanity
Ethnologue counts just 23 languages spoken by more than half the world's people. The other ~7,140 share the remaining half.

That imbalance is the root of the risk. A language spoken by a few thousand people in one valley can vanish in a single generation if parents switch to a bigger language at home.
Not every big number means safe: most of the world's languages have small speaker communities, which is normal — what matters is whether children are still learning them.
02 · The vitality scale
From unsafe to silent
UNESCO grades languages by one test above all: are children still learning it? About 2,500 languages sit somewhere on this slide.
607
Unsafe
Most children speak it, but only at home
632
Definitely endangered
Children no longer learn it as a mother tongue
502
Severely endangered
Spoken by grandparents; parents understand but don't pass it on
538
Critically endangered
Youngest speakers are grandparents, speaking it rarely
200+
Extinct since c.1950
No speakers left (UNESCO: “200+”)

03 · The pace
One every three months — heading for one a month
The Catalogue of Endangered Languages counted 227 languages lost since 1960. A 2022 global model warns the rate could triple within 40 years.
Solid line: measured (ELCat, 1960–2013, shown as a straight average). Dashed line: modeled projection (Bromham et al., Nature Ecology & Evolution, 2022); the path between endpoints is illustrative.
04 · Where the words are
Diversity lives near the equator
Ten countries hold more than half of all languages. Papua New Guinea alone has 841 — more than any other country.

05 · The stakes
What goes quiet
A language carries names for plants, kin, places and ideas that often exist nowhere else. When one stops being passed on, the losses compound.

What predicts loss? Across 6,511 languages, Bromham et al. found more roads and more years of schooling go with higher endangerment — not contact with other languages on its own. Schooling only in a dominant language is a driver; bilingual schooling is a remedy.
06 · What you can do
Why it matters — and what helps
Languages aren't lost to time alone; they're lost when the next generation stops hearing them. That is reversible.
Record the elders
If a heritage language runs in your family, record it — songs, recipes, everyday talk. Archives such as ELAR and the Endangered Languages Project accept community recordings.
Back mother-tongue schooling
UNESCO finds 40% of people lack education in a language they understand. Supporting bilingual programmes helps both learning and language survival.
Use it, even a little
Greetings, place names, an evening class — every new speaker widens the circle. The UN's International Decade of Indigenous Languages runs 2022–2032.
