Such policies refuse to tolerate even minor crimes; proponents argue that this will improve the quality of life of local residents. However, critics of zero tolerance policies believe that such policies neglect investigation on a case-by-case basis and may lead to unreasonably harsh penalties for crimes.

In international development Quality of life has been deemed an important concept in the field of international development because it allows development to be analyzed on a measure that is generally accepted as more comprehensive than standard of living. Within development theory, however, there are varying ideas concerning what constitutes desirable change for a particular society. The different ways that quality of life is defined by institutions, therefore, shape how these organizations work for its improvement as a whole. Organisations such as the World Bank, for example, declare a goal of "working for a world free of poverty", with poverty defined as a lack of basic human needs, such as food, water, shelter, freedom, access to education, healthcare, or employment. In other words, poverty is defined as a low
