Tepito is a barrio located in Colonia Morelos in the Cuauhtémoc borough of Mexico City bordered by Avenida del Trabajo, Paseo de la Reforma, Eje 1 and Eje 2. Most of the neighborhood is taken up by the colorful tianguis or open-air market. Tepito's economy has been linked to tianguis or traditional open air markets since pre-Hispanic times.
Estimates of the area's population may vary from 38,000 to 120,000 residents, with an estimated 10,000 more who come in during the day to sell in the market. It also has been a lower-class neighborhood since pre-Hispanic times, which has known crime since the same period. It is famously known as the "Barrio Bravo" or fierce neighborhood. Most crimes here involve the counterfeiting of goods but it is robbery that gives the area its reputation and can cause problems for sellers by scaring away their customers.
Tepito is home to a subculture that has attracted the attention of academics and artists. Art exhibitions have been based on Tepito and the area boasts a number of literary journals to which residents contribute.
