The term quality of life is difficult to define accurately, because it combines many different aspects, including economic, sociological, psychological and even these belonging to political science. Reflections on the quality of life appeared somewhere half of the twentieth century and are associated with attempts to realize the idea of so-called welfare economics, calling for the achievement of such economic development of the country in which the welfare state might occur. And then came the idea that quality of life is determined by the Gross Domestic Product index. But when discussing this issue, it turned out that one must also consider the Human Development Index, indicating the perspectives of other disciplines on this issue. So, the quality of life combines among other satisfaction of life, which is determined by many other factors.
