This working paper analyzes the significant reforms in Brazil from 1995 to 2009 that led to improvements in poverty and inequality indicators, particularly through government interventions in public education, minimum wage laws, social security, and assistance transfers. Despite economic challenges in preceding decades, Brazil experienced sustained pro-poor growth starting in the mid-2000s, resulting in a notable reduction in poverty levels and income inequality. The document also discusses the data sets and methodologies used for tracking these trends, highlighting the importance of reliable data for poverty and inequality research.
