This chart takes a snapshot of the Top 50 countries which currently have the highest daily COVID-19 cases per capita. It groups the countries by World Bank income group and ranks them within each group by the case rate.
The case rate expresses COVID-19 cases relative to the size of the population. To remove intra-week volatility in the reported data, the indicator is transformed into a 7-day trailing average (the average value of the latest observation and the preceding 6 days).
By relating COVID-19 cases to population size, we get a measure of the prevalence of confirmed infections within the community tested. In contrast to the absolute case toll, the case rate provides an indication of the performance of country or group of countries in terms of protecting its population against infection.
Finally, it should be noted that limitations to testing will mean that the number of confirmed cases is lower than the true number of infections.
