The LexisNexis Risk Solution data and analytics team designed the COVID-19 data set by combining proprietary data assets and models from LexisNexis Health Care with data from the Johns Hopkins University Center for Systems Science and Engineering, which includes data from WHO, CDC, and other independent sources, and data from the American Hospital Association (AHA).

The COVID-19 Data Resource Center features heat maps with insights that identify at-risk populations and correlated gaps in provider coverage. Each county is assigned a percentile rank on a scale of 0 (low-risk) to 100 (high-risk) across various parameters. The map is updated regularly to quickly address the care needs of the community.
