The Numbers Behind São Paulo's Migration Crisis: 412,000 New Arrivals and a City Running Out of Room

São Paulo registered 412,000 new migrant arrivals in the first six months of 2026, according to figures released Thursday by the Secretaria Municipal de Assistência e Desenvolvimento Social, a 38 percent jump over the same period last year and the highest half-year total the city has recorded in more than a decade. Mayor Ricardo Nunes sent a formal letter to the Lula administration this week requesting emergency federal co-funding, arguing the municipal budget cannot sustain the current pace of intake without direct transfers from Brasília.

The surge matters now for reasons that stretch well beyond São Paulo's borders. Global displacement is running at record levels: Venezuela's ongoing economic collapse, a deadly earthquake that struck that country last week, and migration flows reshaping cities from Bogotá to Warsaw have pushed hundreds of thousands of people toward Brazil, which shares a 17,000-kilometre land border with ten countries. São Paulo, as the continent's largest urban economy and home to Brazil's main international airport in Guarulhos, is the first stop for most arrivals who enter legally, and many who don't.

Where the People Are, and What It Costs

The pressure is most visible in specific postal codes. The Centro Histórico district, particularly the stretch of streets around Praça da Sé and Largo do Paissandu, has seen overnight shelter occupancy climb to 118 percent of designed capacity at several municipal facilities run by the Centro de Acolhida Adulto, the city's main intake network. The Bras neighbourhood, historically the entry point for Bolivian textile workers beginning in the 1980s, is now receiving Venezuelans, Haitians and, in growing numbers, West Africans displaced by flooding that has devastated Côte d'Ivoire and neighbouring countries this rainy season.

The Centro de Referência para Imigrantes, located on Rua Conselheiro Furtado in Liberdade, processed 9,200 individual cases in June alone, the highest monthly figure in the centre's twelve-year history and nearly double its June 2024 caseload of 4,800. The centre offers Portuguese-language classes, document regularisation support and job referrals, but staff told the Secretaria this week that waiting times for an initial appointment have stretched to 34 days, up from eleven days in January.

The fiscal arithmetic is stark. The Prefeitura de São Paulo allocated R$487 million to migrant assistance programs for the full year 2026, a figure city officials now say will be exhausted by late September at current burn rates. Each shelter bed in the Centro de Acolhida network costs the city approximately R$95 per person per night. With peak occupancy across 41 facilities running at roughly 28,000 beds per night, that translates to R$2.66 million in daily expenditure on shelter alone, before factoring in health services, school enrolment for minors or the legal aid pipeline.

What Brasília Has, and Hasn't, Promised

The federal government's Política Nacional de Migrações, Refúgio e Apatridia, updated by decree in March 2025, does establish a cost-sharing mechanism between the União and municipalities, but the transfer formula caps federal contributions at 40 percent of verified municipal spending. São Paulo's Secretaria de Finanças says that cap leaves a gap of roughly R$180 million over the projected annual shortfall. City hall wants the ceiling raised to 60 percent and wants the reimbursement cycle cut from the current 90-day lag to 30 days.

Federal officials in Brasília have not publicly committed to either demand, though a working group inside the Ministério dos Direitos Humanos e da Cidadania is understood to be reviewing the transfer formula. A response is expected before Congress rises for its mid-year recess on July 18.

For the tens of thousands of people already in the system, the practical calculus is more immediate. The Centro de Referência para Imigrantes is advising new arrivals to bring all identity documents, even partial ones, to their first appointment and to register children in São Paulo's municipal school network through the Secretaria Municipal de Educação's online portal, which accepts enrolment without a CPF number. Shelter space is being prioritised for families with children under twelve and single women. For everyone else, the wait, and the uncertainty, continues to grow longer.
