Mexico’s two largest cities, Mexico City and Guadalajara, have large number of tianguis that employ many people. Officially, Guadalajara has 143 registered tianguis in the city, with no new ones approved since 1997. These tianguis have over 40,000 stalls combined. These stalls pay a nominal fee of between 2.5 and 3 pesos per square meter for the right to be there. About half of the tianguis in Guadalajara operate once a week, about 15% every two weeks and the rest about once a month. In Guadalajara, it is estimated that approximately 95,000 people work in this sector.
