How much of the world can you talk to?

English is the world's most far-reaching language: counting both first-language and additional speakers, it reaches an estimated 20.2% of the world's population, or roughly 1.6 billion people. No single language reaches even a quarter of humanity. But English, Spanish, Chinese, Hindi, and Arabic together reach 53.6%, which is more than half the world from 5 languages.

How far does each language get you on its own?

Every language that on its own reaches at least 1% of the world's population, ranked. "Countries" is the number of countries where it is spoken at all.

What happens when you add a second language?

Reach does not simply add up. Two languages spoken by the same people overlap, so the gain from a second language depends far more on where it is spoken than on how many speakers it has. The last column is how many percentage points the combination adds over its strongest single language.

How these numbers are calculated

For every country, the share of the population speaking each of your languages is added together and capped at 100%, then multiplied by that country's population. Summing across all 203 countries gives the number of people reached, which is divided by a world population of 8.1 billion.

The cap matters. In a country where 90% speak Hindi and 40% speak English, the two do not reach 130% of the population: they reach at most everyone. Capping per country is what makes the second language add less than its raw speaker count suggests.

Speaker shares come from Unicode CLDR and count both first-language and additional speakers, which is why English reaches far more people than its native-speaker count. These are estimates, not census figures, and the totals should be read as approximations. A pair below 0.5% of a country's population is excluded unless the language has official status there.

"Reach" here means a shared language exists, not that conversation is guaranteed. Someone counted as an English speaker in a country where English is a second language may have very different fluency from a native speaker.

Common questions

What is the most useful language to learn?
By raw reach, English at 20.2% of the world's population. But reach depends on what you already speak: the tables above show that adding a language spoken in places your existing languages do not cover gains far more than adding one with more total speakers. Spanish adds 5.8% to English, while Chinese adds 16.3%.
How much of the world speaks English?
About 20.2% of the world's population, or roughly 1.6 billion people, counting both first-language and additional speakers. English is spoken in 118 countries, more than any other language, which is why it reaches further than languages with more native speakers.
Which two languages together reach the most people?
English + Chinese reach 36.5% of the world's population between them, more than any other pair in this comparison.
Why do the percentages not simply add up?
Because coverage is capped at 100% within each country. Where two of your languages are spoken by the same people, the overlap is counted once. A second language therefore adds most when it is spoken somewhere your first is not.
Where does the data come from?
Speaker shares per country come from Unicode CLDR, covering 411 languages across 203 countries and territories. Population figures come from the same source. Everything is an estimate rather than a census count.

Language shares and population: Unicode CLDR. Country facts: mledoze/countries (ODbL 1.0). Reach figures are estimates derived from population and reported speaker share, capped at 100% per country.
