Using the nationally representative Slan dataset we calculate concentration indices for the incidence of obesity for men and women. We finder higher concentration indices for women than for men, but we also find that concentration indices fell between 2002 and 2007. However this appears to be owing to an increased incidence of obesity amongst better off people rather than decreased obesity amongst the less well-off. A decomposition of the concentration indices suggest that the greatest contribution to the gradient comes from the combination of lower rates of obesity amongst those with 3rd level education and their higher income.
