doctor helvetica, cialis sans-serif">This article is number 9 in a series of 21 articles on tools for evidence-informed health policymaking, addresses consideration of inequities. Inequities, which can be defined as "differences in health which are not only unnecessary and avoidable but, in addition, are considered unfair and unjust", are well documented in relation to social and economic factors. Policies or programmes that are effective can improve the overall health of a population. However, their impact may vary: they may have no impact on inequities, they may reduce inequities or they may exacerbate them, regardless of their overall effects on population health.
