This Viewer easily visualizes COVID-19 data along with several types of information that provide context for more nuanced analysis. The map shows the prevalence of COVID-19 cases/deaths, via population-weighted measures; pyramids of the distribution of age, age and sex, urbanization (population estimates by type of settlement); and trends for daily COVID-19 cases/deaths.
By visualizing the prevalence of cases/deaths per 100,000 persons, the Viewer enables better understanding of the magnitude of impacts to populations of very different sizes, across space, and over time. Data on age and sex are included, as they are risk factors for COVID-19 transmission and 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 aerosols to increased COVID-19 mortality. Data is at country level, and subnational level (state, city, or county) if available, including across country boundaries.
The information on COVID-19 cases is updated once per day; please refresh your browser for the latest data.
