The COVID-19 risk level dataset records daily county-level risk classifications from April 2, 2021, to December 15, 2022. This data originates from the official COVID-19 risk level disclosure platform of the State Council (original URL now inactive), with risk levels categorized into high-risk, medium-risk, and low-risk.
Prior to July 21, 2022, the platform only published medium-risk and high-risk areas, with remaining regions classified as low-risk. From July 21 to November 15, 2022, the platform explicitly listed low-risk, medium-risk, and high-risk areas, while other regions were designated as regularized prevention and control areas. After November 15, 2022, only low-risk and high-risk areas were published, with other regions maintaining regularized prevention and control status. For detailed policy changes regarding risk classification definitions, please consult relevant policy archives and official reports.
The dataset contains risk status variables: high_risk and mid_risk. A value of 1 indicates that the county contains areas designated as "high-risk" or "medium-risk" respectively. Note that counties may simultaneously contain both high-risk and medium-risk areas, thus both variables could equal 1.
This dataset only aggregates risk levels at the county level. Original data included sub-district level risk information. Researchers interested in granular data should contact the original authors.
