  Since the beginning of the 20th century, São Paulo has been one of the main economic centers of Latin America. With the First and Second World Wars and the Great Depression, coffee exports to the United States and Europe were heavily affected, forcing the rich coffee growers to invest in the industrial activities that would make São Paulo the largest industrial center in Brazil. The new job vacancies contributed to attract a significant number of immigrants (mainly from Italy) and migrants, especially from the Northeastern states. From a population of only 32.000 people in 1880, São Paulo now had 8.5 million inhabitants in 1980. The rapid population growth has brought many problems for the city.
  
  São Paulo is practically all served by the water supply network. The city consumes an average of 221 liters of water/inhabitant/day while the UN recommends the consumption of 110 liters/day. The water loss is 30.8%. However, between 11 and 12.8% of households do not have a sewage system, depositing waste in pits and ditches. Sixty percent of the sewage collected is treated. According to data from IBGE and Eletropaulo, the electricity grid serves almost 100% of households. The fixed telephony network is still precarious, with coverage of 67.2%. Household garbage collection covers all regions of the municipality but is still insufficient, reaching around 94% of the demand in districts such as Parelheiros and Perus. About 80% of the garbage produced daily by Paulistas is exported to other cities, such as Caieiras and Guarulhos. Recycling accounts for about 1% of the 15,000 metric tons of waste produced daily.
