Population within the city’s own limits: the latest official figure of its municipality (a comune, commune, Gemeinde, incorporated place…) as Wikidata gives it, from the census or the statistics office’s estimate, else GeoNames’ figure. Districts and boroughs of a city are not cities of their own. Administrative limits differ by country, so city-proper figures are not strictly comparable across borders; China’s cities count their urban districts, not the whole prefecture.
