NIH’s All of Us research program announced it has reached its goal of collecting genetic and health data from 1 million Americans representative of the country’s diversity. The cohort includes linked electronic health records, biospecimens and a range of social and environmental data designed to support precision‑medicine research. Reaching the million‑participant mark gives researchers a larger, more diverse resource to study genetic associations, health disparities and population‑level disease drivers. NIH officials said the dataset will accelerate discovery and support translational projects across academic, clinical and commercial partners.
