65 attributes across 9 domains: identity (name, email, phone, SSN placeholder, DOB), geography (state, city, ZIP — correlated), social (marital status, education, employment), financial (income bracket, insurance type, EIN), behavioral (smoking, alcohol, exercise, sleep), health basics (height, weight, BMI, waist, A1c, blood pressure), health conditions (diabetes, hypertension, CKD, cancer, depression — age-conditioned), utilization (visits, ER, hospitalizations), and medications.
Every distribution is benchmarked against published US references: ACS 2022, NHANES 2017–2020, CDC NDSS 2022, KFF 2023, BLS 2023, US Census 2020. See the full fidelity report →
No. Every record is synthetically generated from published reference distributions. No real person's data enters the system at any point.
The data is synthetic by construction — no protected health information exists. Consult your compliance officer for your specific use case.
