What counts as an urban area? The UN uses satellite imagery to map built-up land, and treats each continuous stretch of built-up land as an urban area. This means that urban areas can extend beyond official city boundaries, and may include multiple cities and towns within a single urban area.
Can an urban area be smaller than its city? Yes. While most cities have urban areas larger than their administrative boundaries, some cities have extensive administrative limits that include sparsely populated areas.
