Nemotron-Personas-India is a synthetic human dataset for India released by NVIDIA in 2025. It aims to improve the diversity of synthetic data, reduce model bias, and prevent model collapse by reflecting the real geographical and demographic distribution of India. It is mainly used to support Indian model developers in building sovereign AI systems that can incorporate regionally specific demographic features and cultural backgrounds. This dataset contains 3 million records, each with 7 virtual character roles, totaling approximately 21 million character descriptions and about 7.7 billion tokens, of which 2.9 billion tokens are character-related information. The data covers 36 states and union territories of India, 640 districts, and includes approximately 560,000 unique names. It is provided in three language versions: English, Devanagari, and Latin, with approximately 1 million records in each language version. This dataset is based on real demographic and geographical distribution information from the 2011 Indian census and election registers. All characters are completely virtual and do not correspond to any real personal identity information; data on minors under the age of 18 has also been excluded.

Data Fields:

The dataset contains 27 valid data fields (excluding UUID), divided into 7 personality attribute fields and 20 demographic feature fields:

• Character attribute fields: covering professional profile, language habits, sports interests, artistic talents, travel preferences, dietary habits, and overall personality.
• Demographic characteristics fields include: cultural background, skills and expertise, interests and hobbies, career goals, gender, age, language, marital status, education level, occupation type, language use, and region and country of residence (fixed to India).
