Censuses, right to information and the effectiveness of social welfare rights

Demographic censuses are tools used by countries to gather statistical data on their populations and to understand the quantitative and qualitative changes in their conformation. Statistical research on population size, geographic distribution, level of education, work and income, among others, are essential for the monitoring of public policies, definition of electoral representation and distribution of financial resources. This article examines the case of the postponement and subsequent cancellation of the Brazilian census scheduled for 2020, assessing the constitutional impacts of the lack of updated data and the relationships between information blackouts, government accountability and the effectiveness of social welfare rights.
