Country Data gives you structured facts for every country in the world — capitals, populations, languages, currencies, borders, timezones, and flags — instantly, without web searching or parsing Wikipedia.

It covers all 195 recognized countries with consistent, machine-readable data. Look up a single country by name, ISO code, or currency code. Filter all countries in a region or all countries that speak a given language. Compare two countries side by side. The data is always structured, making it easy to use in tables, reports, or further analysis.
