This Viewer visualizes data on COVID-19 along with several risk factors. The map shows the prevalence of COVID-19 cases/deaths. Click on a country to obtain a graph of trends in daily reported COVID-19 cases/deaths, population pyramids showing the age and sex distribution, and a figure portraying the degree of urbanization. For selected countries this is available for subnational units (i.e., states and counties in the United States by zooming in). Draw a circle or polygons to access the population distributions and degree of urbanization data for custom areas.
The Viewer enables a better understanding of the magnitude of potential COVID-19 impacts on populations of different sizes, age structures, and levels of urbanization. Data on age and sex are included because older populations and males have been shown to be disproportionately at risk of COVID-19 mortality, and urbanization is linked to higher transmission risk. Elevation data is potentially linked to the disease mortality, as is air quality as measured by Aerosol Optical Depth (AOD)—preliminary studies link particulate matter to increased COVID-19 mortality.
The information on COVID-19 cases is updated once per day; please refresh your browser for the latest data.
