owid/covid-19-data

This repository was the main home for Our World in Data's COVID-19 dataset, which tracked cases, deaths, hospitalisations, testing, and vaccinations across every country in the world. The data was updated daily throughout the pandemic and was widely used by researchers, journalists, and governments. The repository is now archived: the last update was in August 2024, and no new data will be added here. The project is split into two parts. The first is a folder of final, ready-to-use data files in CSV and other formats, intended for anyone who simply wants the numbers. The second is the full pipeline of scripts that produced those files, which is for people who want to understand how the data was collected and processed, or who want to contribute to the methodology. Because this repository is no longer maintained, the README directs people who want current COVID-19 figures to a separate, live data catalog that Our World in Data continues to update. That resource also provides documentation about what each metric means and how to access any of their other datasets programmatically. For anyone who used this repository for research or automated data pipelines, the archived snapshot still contains a complete historical record up to the cutoff date. The data methodology and variable definitions are documented both inside the repository and in external technical documentation linked from the README.
