How do these cities really compare: size, density, growth, greenery, roads, climate and access?. Side-by-side brief for up to 4 of 6,902 cities (every city with 100k+ people, 176 countries). Each city is measured three ways so comparisons are fair: the continuous built-up agglomeration seen from space (EU GHSL), a fixed 10 km disc, and the OSM administrative polygon. Population 2000 and 2025, density, built-up share, built-area greenness, centre-3 km road/rail/foot-path length and park share (OpenStreetMap via Overture), elevation and relief, 1991-2020 temperature and rainfall measured at the nearest NOAA GHCN station (never model-filled), nearest large airport (IATA) and seaport with km. Every metric also comes as a percentile among all 6,902 cities. Sources and data dates in the attribution. Facts only. Routes: /answer (cities*); /search (q*); /coverage.
