+# COVID Tracking Project — US states daily (archived)
+
+The COVID Tracking Project was a volunteer-run effort that ended 2021-03-07. State data
+was assembled from each state's public dashboard, with curatorial corrections. Authoritative
+until federal reporting (HHS Protect → NHSN HRD) caught up.
+
+**Source:** <https://covidtracking.com/>
+
+## Coverage
+
+- **Time:** 2020-01-13 → 2021-03-07
+- **Cadence:** `daily` (observed median spacing: 1 days)
+- **Geography levels:** `subnational-state` — 56 unique location IDs
+- **Countries:** US
+- **Pathogens:** `sars-cov-2`
+- **Surveillance category:** `respiratory`
+- **Rows:** 20,780
+
+## Columns
+
+| Column | Unit | value_type | Aggregation | Description |
+|--------|------|------------|-------------|-------------|
+| `positive` | cases (cumulative) | `cumulative` | `max` | Cumulative confirmed positives reported by the state |
+| `death` | deaths (cumulative) | `cumulative` | `max` | Cumulative confirmed COVID-19 deaths |
+| `hospitalizedCurrently` | patients | `stock` | `mean` | Patients currently hospitalised with COVID-19 (point-in-time) |
+| `inIcuCurrently` | patients | `stock` | `mean` | Patients currently in ICU with COVID-19 (point-in-time) |
+| `onVentilatorCurrently` | patients | `stock` | `mean` | Patients currently on a ventilator with COVID-19 (point-in-time) |
+| `totalTestResults` | tests (cumulative) | `cumulative` | `max` | Cumulative tests resulted (PCR + antigen mix; varies by state) |
+| `positiveIncrease` | cases/day | `incident` | `sum` | Daily new positives (state-derived diff of `positive`) |
+| `deathIncrease` | deaths/day | `incident` | `sum` | Daily new deaths |
+| `hospitalizedIncrease` | admissions/day | `incident` | `sum` | Daily new hospitalisations (irregular reporting; many states never populated) |
+| `totalTestResultsIncrease` | tests/day | `incident` | `sum` | Daily new tests |
+
+### Additional data columns
+
+- **`location_name`** — State postal code as reported. `location_id` is FIPS.
+
+## 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.
+
+- **`hospitalizedIncrease`** — Many states never reported daily new hospitalisations — column is NaN-heavy. Prefer NHSN HRD's `totalconfc19newadm` for analysis spanning 2020-08+.
+- **`totalTestResults`** — PCR / antigen mix differs by state and shifted over time. Don't compare raw test counts across states.
+
+## Access
+
+- **Availability:** `inactive`
+- **Access type:** `csv`
