A language hotspot is a place with an unusually large number of different languages. On this map the term means a country or region packed with languages, such as Papua New Guinea. It does not measure how many people speak them.
Key takeaways
- A language hotspot is a place with many different languages, counted by language rather than by speaker.
- Papua New Guinea has 864 living languages on this map, from 50 language families.
- Indonesia has 708 and Nigeria 528.
- A language spoken in several countries is counted in each, so country totals add up to more than the world total.
How hotspots work
A language hotspot is a place where unusually many languages are spoken. Researchers count the languages within a country or region and compare. The count depends on how languages are defined and separated, which is partly a matter of judgement, so any single number is a snapshot of one classification, here Glottolog's [1].
Two things separate a hotspot from a place with many speakers. First, it counts languages, not people. A country of millions can have only a few languages, and a small one can have hundreds. Second, many languages in one place does not mean they are all spoken by large groups. Often the opposite holds, with most of them spoken by small communities.
The homepage section on countries with the most languages lists the leaders and gives some reasons why diversity gathers in places: rugged land, islands, many separate communities and a long history of settlement. This page goes deeper on the counting rather than repeating that.
Counts also depend on method. Where a language crosses borders it is counted in each country where it is spoken, so country totals add up to more than the world total. And the map's country shares of speakers come from Unicode's CLDR territory data [2].
An example from our data
Papua New Guinea has 864 living languages on this map from 50 families. Its top language is Tok Pisin, with a share of 71%, a CLDR-based estimate. Even there, one language reaches most people while hundreds of others each serve a small group.
Indonesia has 708 languages from 37 families, with Standard Indonesian at 64%. Nigeria has 528 languages from 9 families, and English at 53%. Compare the three with the full country list. Together they show that diversity can come from many separate families, as in Papua New Guinea, or from fewer families with many close relatives.
The thing people get wrong
A hotspot is not a measure of how many people are multilingual, nor of how healthy the languages are. Many hotspot languages are also at risk (see endangered languages), but that is a separate fact, checked language by language.
Also, researchers sometimes use "hotspot" in a narrower technical way, for areas where diversity and threat coincide. Here it simply means a country with many languages. The map's counts rely on atlases that vary in detail and age.
Frequently asked questions
Which country has the most languages?
On this map, Papua New Guinea, with 864 living languages, followed by Indonesia (708) and Nigeria (528).
Does a hotspot mean lots of people speak those languages?
No. It counts languages, not speakers. A country can have hundreds of languages and a few of them can dominate daily life.
