Nemotron-Personas-Singapore is a dataset of synthetic people from Singapore released by NVIDIA in 2026. It aims to reflect the real-world population, geographical, and personality characteristics of Singapore. Its primary purpose is to support the development of sovereign AI systems, enhance the diversity of synthetic data, mitigate model bias, and prevent model collapse. This dataset contains 148,000 records, each with 6 virtual character roles, totaling 888,000 character descriptions and approximately 118 million tokens, of which 48 million tokens are character-related information. The data covers 55 planning areas in Singapore and includes approximately 146,000 unique names. This dataset was generated based on the 2024 Singapore Census, name authorization data from the National Library Board (NLB), and official information provided by the Housing & Development Board (CEA). 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 20 valid data fields (excluding UUID), divided into 6 personality attribute fields and 14 demographic feature fields:

• Character attribute fields: covering occupation profile, sports hobbies, 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, marital status, education level, occupation type, and place of residence and country (fixed to Singapore).
