Data source shown on the chart: UNESCO (1957) and other sources. Original chart unaltered, displayed smaller, with its source, logo and licence stamp retained. Historical and modern comparisons need caution because literacy definitions and population coverage changed. This illustrates the site’s output; AiCoN has not independently verified its data.

What it is

Our World in Data (OWID) is a free website of charts, data and short explainers on big world topics such as poverty, health, population, climate and energy. It describes itself as "a free, non-profit website" made by researchers at the University of Oxford together with the non-profit Global Change Data Lab. It says it covers more than 120 topics and has over 14,000 interactive charts. It is not an AI tool. We included it as a free educational resource from an official source.

Is it free?

Yes. OWID calls itself "a free, non-profit website" and says it is funded by grants and reader donations. We saw no account or subscription needed to read or use the charts on the pages we read. There are optional newsletters and donations.

The FAQ permits attributed reuse of OWID-made charts with its logo and CC BY stamp, but third-party data has its own terms. The logo appears only as part of the complete chart, not as a separate endorsement mark. Other claims retain their original source-check date. Original publication date is unchanged.
