WHO estimates 14.9 million excess deaths associated with the pandemic in 2020–2021

WHO published an estimate of approximately 14.9 million excess deaths associated directly or indirectly with the COVID-19 pandemic during 2020 and 2021, with an uncertainty range of 13.3 million to 16.6 million. In the causal graph this event strengthens COVID-19 pandemic, a driver that weakens Life expectancy at birth — a worsening welfare path.

WHO published an estimate of approximately 14.9 million excess deaths associated directly or indirectly with the COVID-19 pandemic during 2020 and 2021, with an uncertainty range of 13.3 million to 16.6 million. This is an outcome measurement of the pandemic's scale, not a new transmission event and not a person-level responsibility allocation.
