Poor children have been fatter than rich ones since around the 1980s. But over the past decade the rich have started to slim down, as the poor have got bigger. This is true in poor Camberwell and posh Dulwich, where rates of childhood obesity have respectively risen by ten percentage points and fallen by two in the past six years. And it is true of the country at large (see chart).
