+# FluSight Forecast Hub — flu hospital admission target
+
+This source represents only the **truth** half of the hub. Model forecasts live in
+`model-output/` in the same repo and will become a separate `flusight-forecast-hub-models`
+dataset (forecasts are a different shape — one row per (team, model, reference_date,
+target, horizon, location, output_type, value) — and need a separate schema treatment).

+
+## Coverage
+
+- **Time:** 2022-02-05 → 2026-04-18
+- **Cadence:** `weekly` (observed median spacing: 7 days)
+- **Geography levels:** `national`, `subnational-state` — 53 unique location IDs
+- **Countries:** US
+- **Pathogens:** `influenza`
+- **Surveillance category:** `respiratory`
+- **Rows:** 11,660
+
+## Columns
+
+| Column | Unit | value_type | Aggregation | Description |
+|--------|------|------------|-------------|-------------|
+| `value` | admissions/week | `incident` | `sum` | Confirmed flu hospital admissions for the epiweek (FluSight scoring target) |
+| `weekly_rate` | admissions/week per 100k | `rate` | `rate` | Weekly admission rate per 100k population |
+
+### Additional data columns
+
+- **`location_name`** — State name as published by the hub. `location_id` is FIPS for states / `US` for national.
+
+## Interpretation caveats
+
+Things that may differ from how other sources define a similar measure. If you're combining this dataset with another, read these first.
+
+- **`value`** — This is the *target truth* file the hub uses for scoring. It is derived from NHSN HRD
+(`derived_from`) and may lag NHSN by one cycle while the hub freezes the truth value.
+For the live admissions series use `nhsn-hrd.totalconfflunewadm` directly.
