An urban area (urbanized area agglomeration or urban centre) is a continuously built up landmass of urban development. National census authorities in Australia, Canada, France, the United Kingdom and the United States designate urban areas. Except in Australia, the authorities use a minimum urban density definition of 400 persons per square kilometer (or the nearly identical 1,000 per square mile in the United States).
