At a glance
Each figure is drawn against the rest of the world, so a number means something before you have any other market to compare it with.

86% of 123.2M people use the internet, per the World Bank's 2024 figure. CLDR population multiplied by that share, so read it as an estimate rather than a headcount.

Very low proficiency on the EF EPI 2025 scale. The sample is self-selected online test takers, so treat it as colour for a discussion. It never enters any score on this site.

Share of adults who can read, as recorded in CLDR territory data. Low literacy shifts a product toward icons, audio, and video before it shifts toward another language.
What people speak
Shares count first and second languages, so they sum past 100% and one bilingual person is counted twice.

Filled bars are nationally official languages. Every bar is drawn against the largest language rather than against 100%, so a 1% language stays visible.
One country understates a language. CLDR records diaspora too, so a language usually reaches further than any single page shows. The language profiles show each one's full footprint.
