In Hungary, as well as worldwide, one of the main objects of health sociology research is social inequality, focusing mainly on the inequalities stemming from health conditions. The main question is where and how these inequalities appear and evolve during the whole life-history, and how they sustain. In modern societies these differences clearly appear in the markers of health conditions like subjective well-being. The rate of inequalities are defined by essential sociocultural and sociodemographic variables like residual environment, geographical location, age or gender. A very important attribute of social research is to examine these phenomena on different stages and from various aspects. In my study I investigate these stages and aspects using the relevant theoretical literature.
