In 2005 Mexico had 187,938 "localidades" (lit. "localities" or "settlements"), which are census-designated places, which could be defined as a small town, a large city, or simply as a single unit housing in a rural area whether situated remotely or close to an urban area. A city is defined to be a settlement with more than 2,500 inhabitants. In 2005 there were 2,640 cities with a population between 2,500 and 15,000 inhabitants, 427 with a population between 15,000 and 100,000 inhabitants, 112 with a population between 100,000 and one million, and 11 with a population of more than one million. All cities are considered "urban areas" and represent 76.5% of total population. Settlements with less than 2,500 inhabitants are considered "rural communities" (in fact, more than 80,000 of those settlements have only one or two housing units). Rural population in Mexico is 22.2% of total population.
