Nemotron-Personas-Brazil is a synthetic character dataset for Brazil released in 2026 by NVIDIA in collaboration with WideLabs. It aims to showcase the diversity and richness of Brazil's population to more comprehensively reflect the multidimensional potential population distribution, including regional diversity (such as the North, Northeast, and Midwest), ethnic background, education level, and occupational distribution. This dataset contains 1,000,000 records, each containing 6 composite characters. Each record includes 6 character fields and 14 context fields, which are statistically constructed based on Brazil's official population structure and labor market distribution. The data covers the geographical and demographic distribution of all 26 states and the Federal District of Brazil.
