All 474 datasets declare a licence, a completeness no other catalogue in this series matches. Six of them declare a non-commercial licence, which the city's own law does not accept as open data.

Evidence📊 Independent
what does this mean?The strongest source is an independent non-academic evaluation: an audit office, a government or EU review, or an NGO. It grades who did the looking — not how well the project went. All four grades →

The city's CKAN portal, run by the municipal comptroller's integrity unit, held 474 datasets on 26 July 2026, and 454 of them had been touched within the past year. There is no municipal licence: each publishing body picks from CKAN's stock dropdown, so the catalogue splits across ten licences, led by CC0 (277 datasets) and CC BY (148). Every record declares something, which is rare, but six carry a non-commercial Creative Commons licence that fails the city's own statutory definition of open data. Open Knowledge Brasil ranked São Paulo first among 26 Brazilian capitals in 2023, at 48%.

Live 📅 since 2015

📊 Impact

First of 26 Brazilian state capitals in Open Knowledge Brasil's Índice de Dados Abertos para Cidades 2023, scoring 48%; the index reports that no capital reached 50% and only São Paulo and Belo Horizonte reached a 'medium' level of openness.

🎓 Lesson

Full licence coverage is not the same as a licence policy. São Paulo declares a licence on all 474 datasets, a completeness no other catalogue in this series has matched, yet because each department chooses its own, six datasets sit on the open data portal under a non-commercial licence that the city's own law does not accept as open.

↗ Indicador de Dados Abertos, second half of 2025, reported by ConaciPublished 4 March 2026Semiannual compliance indicator created by CGM-SP in 2025 under Lei 17.901/2023, covering '75 órgãos e entidades da Administração Pública Municipal', measured 24 November to 12 December 2025 and published 4 March 2026. '71% das instituições alcançaram nota superior a 5' ('71% of institutions scored above 5'), leaving roughly 29% below. Half the score is governance (training, updating the CMBD, filing a sectoral plan) and half is portal maturity. CGM-SP, which both runs the portal and calculates the indicator, awarded itself 10.00, so the top grade is not treated here as an achievement. The city's own transparency portal pages on the indicator could not be retrieved directly (Prodam CAPTCHA).
