The coincidence of multiple inequities in health—and as an interlinked concept, the multifaceted nature of poverty—make for a very complex field. Those living at the margins of society suffer numerous and overlapping inequities in health, in voice, in agency, in living conditions. Often, their poverty and ill health keep them in a life of perpetual quicksand. Just as an intervention might spare a child from malaria only to have her die a year later of measles, a policy change in the health sector might be successful in eliminating one source of inequity (. access to care).
