The COVID-19 Forecast Hub — hospital admissions target dataset is a truth-only ingest that tracks confirmed COVID-19 hospital admissions in the United States.

Geography levels include national and subnational-state (53 unique location IDs), limited to the US. The dataset includes a value column representing confirmed COVID-19 hospital admissions per week (as the hub scoring target) and a location_name column for state postal codes. It is derived from NHSN HRD with hub-side freezing applied, providing a single value per date and location. The dataset is open, accessible via GitHub, licensed under cc0-1.0, and classified as tier 1.
