About

Country data, and where it comes from

DigifyWorld publishes figures on 195 countries across ten subjects. Every number is attributed, every gap is shown as a gap.

DigifyWorld publishes country data across ten subjects for all 195 countries: population, economy, human development, currency, languages, public holidays, digital adoption, geography, education and practical travel information.

That works out at roughly 2,145 pages. Figures are tied to named sources, with official national authorities and international data publishers preferred wherever available. Established specialist references are used for practical standards where a single official global dataset is not available.

Why this exists

Country facts are scattered. The plug type is on one site, the public holidays on another, the HDI on a third, and half of them do not say where the number came from or which year it belongs to. DigifyWorld puts the ten things people actually look up in one place, with the source and the data year attached to each.

How we work

• Official sources first. Government statistics offices, central banks and national gazettes where a country publishes its own figures. International bodies such as the World Bank, UNDP and the ITU where a comparable cross-country series is needed.
• Gaps are shown as gaps. Where a country publishes no figure, the page says so. Nothing is estimated, interpolated or carried over from a neighbouring country to fill a blank.
• Data years are stated. A 2023 figure is labelled 2023, not presented as current. Index values are revised between report cycles and we say which cycle a number is from.
• Corrections are welcome. If a figure is wrong or out of date, tell us and we will check it against the source.

What this is not

DigifyWorld is a reference site, not an advisory service. Holiday dates set by lunar or religious observation can shift at short notice. Mains voltage and plug types vary by building age within a country. Economic figures are revised. For anything where being wrong carries a cost, check with the relevant national authority before you act.

Judge it by the sources

DigifyWorld is published as a project rather than under a byline. What matters on a reference site is not who typed the number but whether the number is right and whether you can check it, so every figure names the authority it came from and the year it belongs to.

The sources and methodology page lists the source behind each of the ten subjects and sets out how gaps, revisions and corrections are handled. If a figure looks wrong, tell us and point at the official source; we will check it and correct the page.
