Cover Story: Although all of us sleep, the localities in which we live and the wider ethnic communities with whom we identify affect how well we do so. We use a novel metric—the Problematic Sleep Index—to combine the reported incidence of typical sleep problems across some half a million middle-aged and older adults living in Britain. The study’s scale and the new index of poor sleep allow us to show how unequal sleep quality is, with domiciliary deprivation and ethnicity as powerful influences on these inequalities, as are age and sex—individual differences which the sleep community recognises are especially important. The figure shows the mean Problematic Sleep scores with standard errors, self-declared sex and ethnicity, and an average for Asian, Black, Mixed, and White categories. View this paper
