About Gated Communities and Inequality: Santana do Parnaíba

Santana do Parnaíba is a suburban neighborhood in the northwest of São Paulo. It has a fast growing population and the highest average income of the whole metropolitan region: 9.8MS.
Theresa Caldeira writes as follows about it:
‘Santana do Parnaíba exemplifies what one might call a new suburbanization of São Paulo. Its growth has been neither the traditional expansion of the poor and industrial areas nor the American suburban outgrowth of the 1950s and 1960s, but a new type of suburbanization of the 1980s and 1990s that brings together residence and tertiary activities. Santana do Parnaíba has not had the same economic performance as its adjacent municipalities, Barueri and Cajamar, but it shows more clearly how the area is becoming a new middle- and upper-class enclave. It was the municipality with the highest annual rate of population growth in the 1980s (12.79 percent) and the highest income. Ninety percent of the population increase during the 1980s was due to migration, and it had the highest percentage of growth due to migreation in the metropolitan region: 245 percent. The immigrants were mainly wealthy residents. As the rich settle into areas that have been rural and extremely poor, they create situations of dramatic social inequality, attested to by the fact that the GINI coefficient in Santana do Parnaíba is 0.7102, the highest if the metropolitan region.’ [1]
Caldeira adds in a footnote:
‘In 1980, only 1.5 percent of the economically active population of Santana do Parnaíba made more than 20 MS, whereas 53.7 percent made less than 2 MS. (…) The GINI coefficient for the city of São Paulo is 0.5857 and for the metropolitan region 0.5748.’ [2]
