About
Presents aggregated COVID-19 data for the United States collected daily by The COVID Tracking Project. This dataset offers key metrics relating to cases (confirmed and probable), fatalities, hospitalisation numbers, ICU admissions, ventilation usage, and testing results reported at the national level. Note that data collection for this project concluded on 7 March 2021, and the data reflects the period up to that date. This historical record is essential for studying the early progression of the pandemic in the US.
Columns
The dataset contains 25 columns detailing daily counts and cumulative figures:
- date: The calendar date on which the data was collected.
- states: The count of states and territories included in the national aggregation for that specific day.
- positive: The total number of confirmed plus probable cases.
- positiveIncrease: The daily rise in confirmed and probable cases.
- negative: The total count of unique people with a completed negative PCR test result.
- negativeIncrease: The daily change in negative test results.
- pending: The total number of viral tests yet to be completed.
- recovered: The total number of people identified as recovered from COVID-19 (note: state definitions for this metric vary significantly).
- death: Total fatalities with a confirmed or probable COVID-19 diagnosis.
- deathIncrease: The daily increase in fatalities.
- hospitalizedCurrently: The number of individuals currently admitted to hospital with COVID-19.
- hospitalizedCumulative: The total number of people who have ever been hospitalised.
- hospitalizedIncrease: The daily rise in cumulative hospitalisations.
- inIcuCurrently: The number of individuals currently in the Intensive Care Unit.
- inIcuCumulative: The total number of people who have ever been in the Intensive Care Unit.
- onVentilatorCurrently: The number of individuals currently receiving advanced ventilation support.
- onVentilatorCumulative: The total number of people who have ever received advanced ventilation support.
- totalTestResults: An aggregate estimate of US viral (PCR) testing activity.
- totalTestResultsIncrease: The daily increase in total test results.
- hash: A unique identifying hash for the record.
- dateChecked, hospitalized, lastModified, total, posNeg: These fields are deprecated labels or computed totals and are generally no longer recommended for usage.
Distribution
The primary data file is available in CSV format, with a file size of approximately 82.82 kB. It consists of 25 columns and roughly 420 records, representing daily reporting dates. While core date and testing metrics are fully populated, several crucial fields show substantial missing data, including approximately 15% missing values for current hospitalisation figures and 17% missing values for ICU and ventilator metrics. The
recovered field is entirely null, reflecting challenges in standardizing this metric across states.Usage
This data product is suited for public health analysts studying epidemiological patterns, academic researchers developing time series models of pandemic spread, and journalists reporting on historical US health crisis management. It allows for detailed retrospective analysis of daily mortality and hospital resource consumption during the early phases of the pandemic.
Coverage
The dataset covers the United States at a national aggregation level, including data from various states and territories. The time scope runs from early 2020 until the conclusion of data collection on 7 March 2021. Users should be aware that reporting standards, definitions of hospitalization, and units for testing vary widely among the states contributing to the aggregated figures.
