The US panel is built on the following public sources:

- **Synthetic personas — Nemotron-Personas-USA** (NVIDIA), CC BY 4.0, one million records, 22 fields, 50 states plus Puerto Rico and the US Virgin Islands, adults only. Available on [Hugging Face Datasets](https://huggingface.co/datasets/nvidia/Nemotron-Personas-USA).

- **General Social Survey** (NORC at the University of Chicago), public microdata, used for the calibration of attitudes and for the axis definitions.

- **American Community Survey** (US Census Bureau), 5-year estimates, used for demographic margins and income distributions.

- **ANES and CCES**, public survey data, used to cross-check political motivation and turnout items.

Personas are synthetic. They are not real people, and no answer produced by the service describes an identifiable individual.
