About this ranking
Resident population. Spain and the EU: 1 January, with Spanish figures from the official municipal register (Padrón). Norway: Statistics Norway, 1 January. United States: Census Bureau population estimates for 1 July. United Kingdom regions and local authorities: Office for National Statistics estimates for 30 June. Other countries and the World: World Bank mid-year estimates, which count all residents regardless of legal status or citizenship.
The World Bank series exists for every country, so use it (through compare) to rank countries on one basis.
Every value in the ranking comes from the same publisher and the same period, so the cities are compared on one definition. Equal values share a rank.
