 While the concept of health equity is frequently invoked as a normative standard by scholars, policymakers, and public health practitioners, there is a good deal of disagreement regarding its meaning. There is disagreement, first, on which health differences are avoidable. Some suggest that health differences are avoidable only if they are caused by social processes rather than natural or biological processes (Chang 2002; Whitehead 1992). Others argue that this understanding is too constrained (Preda &amp; Voigt 2015; Wilson 2011). Even if health differences caused by natural processes are not avoidable in the sense of being preventable, these critics suggest, they may be avoidable in the sense of being treatable. Moreover, if inequalities in health are inequitable in part because they are unchosen, as luck egalitarians claim, then it makes sense to identify avoidable health inequalities as those that are amenable to intervention (Preda &amp; Voigt 2015: 30).
