Global Country & City Reference Dataset

This collection includes four detailed datasets describing the hierarchy of global geographic regions, countries, administrative divisions, and cities. Together, they provide a comprehensive and standardized reference for spatial analysis, demographic studies, and location-based applications.

Included Datasets:

· Region–Country Hierarchy: Continent, subregion, intermediate region, and country relationships, with UN M49, ISO2, and ISO3 codes and country surface area (sq. km).

· Country Population by Year: Annual population counts by country, enabling historical and trend analysis.

· Country Time Zones: Complete mapping of countries to time zones, including UTC and daylight-saving offsets.

· Country–Administrative Division–City Hierarchy: Country, first-level and second-level administrative divisions, and cities. Cities include name, alternate names, ASCII name, latitude, longitude, population, elevation (DEM), and time zone for robust geocoding and spatial analytics.

All datasets are standardized using official UN M49 region codes, ISO country codes, World Bank country statistics, and GeoNames city-level data, ensuring high quality, global coverage, and consistency.

Use Cases:
Perfect for global location enrichment, geocoding, regional analytics, market sizing, logistics planning, and demographic analysis.
