# Country Statistics API
> Geographic, demographic and political statistics for every country as an API — the reference a research dashboard, data-journalism piece or analytics tool needs. For each country: its government type, whether it is landlocked, surface area (km²), population, population density (people/km²) and life expectancy (years), enriched with the ISO 3166-1 alpha-2 code and flag emoji. Look a country up by name or code, or RANK every country by any numeric statistic — the ten largest by area, the most densely populated, the highest life expectancy — in ascending or descending order. Search by name or government type, or list them all. This is the country statistics reference — distinct from countries-api (ISO identifiers: codes, dialing, currency, region) and disease-api (public-health data). Served from memory — always fast.
