Covid deaths between January 2020 and December 2021 were around eight times higher than reported. It said the Covid mortality rate among Indian states is not the highest in the world, because of India's large population, but the country accounted for around 22·3% of global excess deaths as of December 31, 2021.
Although reported deaths in that period totalled 5·94 million worldwide, The Lancet paper estimates that 18·2 million people died worldwide because of the pandemic, as measured by excess mortality, over that period.
This is around three times higher than previously estimated. The documented deaths due to Covid in India over that period stood at around 4,89,000, the journal says in the paper “Estimating excess mortality due to the Covid-19 pandemic: a systematic analysis of Covid-19-related mortality, 2020-21".
Excess mortality measures the additional deaths in a given time compared to the number usually expected and is not dependent on how Covid-19 deaths are recorded.
