The Unified Registry for Social Programs of the Brazilian government (Cadastro Único) is a tool for identification and socioeconomic characterization of low-income families that can be used for social programs and policies geared towards such families. The Unified Registry database allows the government to understand exactly which the poorest and most vulnerable segments of the population are.

As such, the Unified Registry is a strategic tool for the coordination of the social promotion and protection network, being paramount for the integration of initiatives from various areas and levels of government aiming to promote the social inclusion of Brazil's low-income population.
