Quality of life is the general well-being of individuals and societies outlining negative and positive features of life. It consists of the expectations of an individual or society for a good life. These expectations are guided by the values, goals and socio-cultural context in which an individual lives. It serves as a reference against which an individual or society can measure the different domains of a personal life. The extent to which one's own life coincides with a desired standard level or put differently the degree to which these domains give satisfaction and as such contribute to one's subjective well-being is called life satisfaction.
