Nature examines the Million Death Study (MDS), which includes “surveys of more than one million households across India,” covering “the period from 1997 to the end of 2013, and will document roughly one million deaths.” According to the news service, Prabhat Jha, an epidemiologist at the University of Toronto, and his colleagues “have coded about 450,000 so far, and have deciphered several compelling trends that are starting to lead to policy changes, such as stronger warning labels on tobacco.” The news service notes, “Public health experts need mortality figures to monitor disease and assess interventions, but quality mortality data are scarce in most developing countries.” Nature provides a series of infographics depicting data from the study (Westly, 12/4).
