# 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`
- **License:** cc-by-4.0
- **Tier:** 3
