What is the real death toll in India?

The chief scientist for the World Health Organisation acknowledges the frailty of the official numbers. Ed Butler speaks to Anthony Masters, the statistics ambassador for the UK's Royal Statistical Society who explains that one way to try to count the number of deaths is through excess deaths figures. But in countries like India there aren't very reliable national mortality statistics to start with, and there's often a long delay in delivering the latest numbers. One man who's done as much as any to sift through the data available is Murad Banaji, an Indian-born mathematician based at the University of Middlesex in the UK. He says the Indian death toll could be between three and eight times higher than the official data. (Picture: A relative of a Covid-19 patient cries in New Delhi, India.
