Why is the phenomenon concentrated in São Paulo?

São Paulo is the only state with multiple cities surpassing the capital because it has a structural anomaly: the capital concentrates 11.4 million inhabitants with enormous internal inequality (Gini 0.56), while cities in the ABC and RMC areas have smaller populations, more homogeneous income, and virtually zero favelas.

São Caetano do Sul, with 162,000 inhabitants, can prioritize education and health in a way that a metropolis of 11 million simply cannot.

Niterói: the most dramatic case outside SP

Separated only by Guanabara Bay, Niterói has HDI 0.837 — 0.038 above Rio de Janeiro (0.799). The difference is explained by the absence of dense favelas equivalent to Complexo do Alemão or Rocinha, by the presence of UFF, and by the concentration of federal public employees and Petrobras workers with high salaries.

For those who live in Niterói and work in Rio, the difference in safety and public services is felt on a daily basis — but real estate prices are already starting to reflect this advantage.

The case of Espírito Santo: Domingos Martins surpasses Vitória by 0.002

With only 32,000 inhabitants and an economy based on German colonization family farming, Domingos Martins has HDI 0.847 — two thousandths above Vitória (0.845).

,845), one of the capitals with the highest HDI in Brazil.

The difference is statistically almost insignificant, but symbolically revealing: the income homogeneity of European settlement communities in Espírito Santo produces indicators that compete with the most developed capital in the state.
