This chart shows the evolution over time of the daily COVID-19 mortality toll in absolute numbers across World Bank income groups. 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).
The absolute expression of the mortality toll is useful to highlight the the contribution of countries or groups of countries to the global total. Mortality rates, which express the absolute toll relative to population size, provide an indication of performance controlling for population size. The absolute numbers however take the view that a life lost is a life lost, no matter where the person happened to live. It offers a valuable perspective on the absolute scale of the pandemic’s death toll.
It should be noted that the different income groups shown here are of very different population size dimensions. The global population as per the 2021 medium-variant projection of World Population Prospects is 7,866 million people, which is distributed as follows:
Low-income countries (LICs): 702 million
In light of these differences in population size, we expect large differences in absolute mortality numbers even if mortality rates were constant across groups.
