The water extracted from Fonte Áurea, or the Golden Fountain, is sold throughout Brazil. The population is 103,765 in an area of 17.26 km². Poá is one of the eleven municipalities in São Paulo considered to be spas by the state of São Paulo, as they meet certain prerequisites defined by state law. This status guarantees these municipalities a larger budget from the state for the development of regional tourism. In addition, the municipality acquires the right to add to its name the title of spa, a term by which it is designated both in official municipal records and in state references. The main sector of Poá's economy is services, since the installation of polluting industries was made difficult after 1970, the year in which it became a spa. In terms of territory, it is one of the smallest municipalities in the state of São Paulo. The verticalization of the city center is discouraged, with the aim of preserving the city's rural atmosphere, with narrow streets and the preservation of several old buildings.
