About
This resource contains daily global measurements related to the Coronavirus disease 2019 (COVID-19). The data chronicles the trajectory of the disease from its emergence in December 2019 through late 2023, capturing key events such as the declaration of a pandemic by the WHO in March 2020. The dataset reflects the massive scale of the global event, noting that as of May 2023, nearly 700 million cases and almost 7 million deaths were reported worldwide. The dataset covers the global vaccination effort, highlighting that 70% of the world's population had received at least one dose by May 2023, contrasting with the much lower 30% first-dose rate in low-income countries.
Columns
The dataset includes 67 columns. Key metrics include:
- iso_code: A unique geographical identifier code, which is 100% valid across records.
- continent: The continental location associated with the record, noting approximately 5% missing values.
- location: The specific country or territory name, with 100% validity.
- date: The daily timestamp, spanning from 1 January 2020 through 17 November 2023.
- total_cases: The cumulative number of reported cases for a location, with a maximum recorded value approaching 772 million.
- new_cases: The daily count of newly confirmed infections, showing 97% validity.
- new_cases_smoothed: A seven-day rolling average used to smooth daily case fluctuations.
- total_deaths: The cumulative number of reported deaths, which are about 83% valid, with the maximum near 6.98 million.
- new_deaths: The daily count of newly reported deaths, showing 97% validity.
- new_deaths_smoothed: A seven-day rolling average of the new daily deaths.
Distribution
The primary data file, named
Coronavirus_cases_daily_update.csv, has a size of approximately 93.15 MB. The data fields demonstrate high quality, with key columns like iso_code, location, and date being 100% valid. The date column contains over 356,000 records, mapping the daily statistics globally across the nearly four-year period. The expected update frequency for this product is annual.Usage
This data product is useful for researchers, analysts, and public health professionals seeking to model the dynamics of a major global health crisis. It allows for tracking the worldwide spread and severity of the virus, noting disparities in impact, such as the fact that the United States consistently led the world in reported cases and deaths. Users can analyse trends in infections and mortality in relation to critical medical interventions, such as the introduction of the first vaccine doses in December 2020. The dataset is instrumental for historical analysis of public health interventions and their effectiveness.
Coverage
The dataset offers global daily coverage, providing statistics from 229 countries and territories. The temporal span runs from 1 January 2020 to 17 November 2023. Geographically, it covers nearly every nation, noting that Turkmenistan is the only territory cited as never having officially reported a case. Users should be aware that the widespread adoption of home testing kits complicated formal tracking systems, meaning that in later stages, effective monitoring of the virus often relied more heavily on wastewater surveillance rather than reported cases.
