Top 50 countries based on the total number of cases are shown.
Bubble size - The size of the bubble is determined by the number of new cases during the last 24 hours. The larger the bubble, the more new cases there have been.
Horizontal position (severity) - Position on the X axis is calculated from the total number of cases and deaths compared to the global average. The higher the index value, the more severely hit the country has been.
Vertical position (growth) - Position on the y axis is calculated from the number of new cases and deaths compared to the world average and is a moving average from the last three days. If the index value is above 1, there have been more new cases & deaths during the previous three days than on average worldwide (growing). Vice versa, the number of new cases & deaths is below the average if the index value is below 1.
Bubble color - Orange bubbles show countries where the number of cases has been growing during the last three days. Those that are green, are having a declining number of cases.
World averages - At severity and growth index value 1. Due to how the index value is calculated, the world average (per 1 million population) for number of cases & deaths is 1.
Note! All figures are per 1 million population so that the countries are comparable.
What is this used for?
The aim of the World Coronavirus Index is to show an easy to understand overview of the global pandemic situation. You can quickly check where the number of cases is growing and declining and how the countries compare to each other in how they have been affected. Also, should there be a second wave, this index is likely to start showing it quickly.
