IBGE Releases Censo 2022 Microdata Under Three-Tier Access Model

Tighter controls seek to reduce reidentification risk from AI and geolocation under Brazil's statistical secrecy and data protection laws.

IBGE

Overview

  • The IBGE published the Censo Demográfico 2022 microdata on Monday with new limits on freely downloadable detail to the state level and additional access controls for more granular files.
  • The institute set a three-level system: public downloads limited to state-level data, a controlled digital tier requiring gov.br authentication and a signed term, and a restricted in-person Sala de Acesso a Dados Restritos (SAR) for the fullest detail.
  • Controlled access files are traceable to each user, carry a digital commitment that forbids reidentification and commercial use, and requests are screened within 48 business hours before release.
  • The SAR at IBGE’s Rio de Janeiro headquarters requires a research project and confidentiality agreements and keeps data inside a secure room so files do not leave the institute.
  • The Comissão Consultiva approved the model with recommendations—including removing the CPF requirement—and researchers and private institutions are awaiting IBGE clarifications on eligibility and some practical rules.
