About WorldCountryData

WorldCountryData is a free, open-access reference for country-level statistics. We compile data from three authoritative sources into clean, comparable profiles for 195 countries, covering population, economy, geography, and quality-of-life indicators.

Our Mission

We exist to make verified country data accessible to everyone: students, researchers, journalists, travelers, and anyone curious about how nations compare. Every number on this site traces back to a named, linkable source.

Unlike AI-generated summaries that can hallucinate statistics, our data pipeline pulls directly from institutional APIs and datasets. If a value is missing from the source, we show a gap instead of guessing. Accuracy matters more than completeness.

Data Sources

Every indicator on WorldCountryData comes from one of three institutional sources. We do not use scraped data, crowdsourced estimates, or AI-generated values.

World Bank Open Data

GDP, GDP per capita, life expectancy, infant mortality, literacy rate, unemployment, inflation, CO2 emissions, and GDP growth. Over 1,600 indicators available; we use 12 core metrics.

UN Population Division

Population estimates, historical population data (30-year trends), demographic projections, and population growth rates for all UN member states.

REST Countries API

Country names, capitals, regions, languages, currencies, borders, timezones, coordinates, flags, and ISO codes (alpha-2 and alpha-3).

Methodology

  1. 1

    Data Collection

    Automated scripts query the World Bank API, REST Countries API, and UN Population Division datasets. Raw responses are cached locally as JSON.

  2. 2

    Validation

    Each data point is checked for type, range, and completeness. Population values must be positive integers. GDP values must be non-negative. Missing values are stored as null, never zero.

  3. 3

    Normalization

    Country names and codes are normalized to ISO 3166-1 (alpha-2 and alpha-3). Currencies use ISO 4217 codes. All monetary values are in current US dollars.

  4. 4

    Static Generation

    Validated data is compiled into static JSON files that power 195 country profiles, 19,000+ comparison pages, and 12 ranking tables. Pages are rebuilt when new World Bank data is published (typically once per year).

Data Quality Principles

  • Every number links to its source. No uncited statistics.
  • Missing data is shown as "N/A", never fabricated.
  • Data year is displayed on every page. No ambiguity about freshness.
  • Rankings use the most recent available year for each indicator.
  • Historical charts show 30 years of trend data where available.
  • Country names follow UN/ISO conventions, not colloquial usage.

Update Schedule

World Bank publishes updated country indicators once per year, typically in Q2. When new data is available, we re-run our data pipeline and rebuild all pages. The current data year is 2025.
