Standard of living is the level of income, comforts and services available, generally applied to a society or location, rather than to an individual. Standard of living is relevant because it is considered to contribute to an individual's quality of life. Standard of living is generally concerned with objective metrics outside an individual's personal control, such as economic, societal, political and environmental matters – such things that an individual might consider when evaluating where to live in the world, or when assessing the success of economic policy.
In international law, an "adequate standard of living" was first described in the Universal Declaration of Human Rights and further described in the International Covenant on Economic, Social and Cultural Rights. To evaluate the impact of policy for sustainable development, different disciplines have defined Decent Living Standards in order to evaluate or compare relative living experience.
During much of its use in economics, improvements to standard of living was thought to be directly connected to economic growth, increase amount of energy consumption and other materials. However, the IPCC Sixth Assessment Report found that literature demonstrates that improvements in sustainable development practices as well as changes in technological efficiency and energy production and use, allow for a Decent Living Standard for all people without fossil fuels and ~15.3 GJ per capita by the end of the 21st century. This allows for climate change mitigation by demand reduction as well as other sustainable development practices.
Standard of living might be evaluated using a number of characteristics including as the quality and availability of employment, class disparity, poverty rate, quality and housing affordability, hours of work required to purchase necessities, gross domestic product, inflation rate, amount of leisure time, access to and quality of healthcare, quality and availability of education, literacy rates, life expectancy, occurrence of diseases, cost of goods and services, infrastructure, access to, quality and affordability of public transportation, national economic growth, economic and political stability, freedom, environmental quality, climate and safety. For the purposes of economics, politics and policy, it is usually compared across time or between groups defined by social, economic or geographical parameters.
The right to an adequate standard of living is a fundamental human right. It is part of the Universal Declaration of Human Rights that was accepted by the General Assembly of the United Nations on December 10, 1948.
Everyone has the right to a standard of living adequate for the health and well-being of him/herself and of his/her family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his/her control.
Furthermore, it has been written down in article 11 of the United Nations' International Covenant on Economic, Social and Cultural Rights.
The predecessor of this right, the Freedom from Want, is one of the Four Freedoms that American President Franklin D. Roosevelt spoke out at his State of the Union of January 6, 1941. According to Roosevelt it is a right every human being everywhere in the world should have. Roosevelt described his third right as follows:
The third is freedom from want which, translated into world terms, means economic understandings which will secure to every nation a healthy peacetime life for its inhabitants, everywhere in the world.
The standard of living varies between individuals depending on different aspects of life. The standard of living consists of the individuals having the basics such as food, shelter, social safety and interaction which all contribute to their wellbeing and what is considered to be a decent living standard.
Experts use a number of different measures and approaches to establish the decent living standard or DLS. The decent living standard revolves around the idea and principle that a majority of the population are in demand for the basics that will allow them to have shelter, food and water, however it is not always able to be maintained for a long period of time.
Standard of living is generally measured by standards such as inflation-adjusted income per person and poverty rate. Other measures such as access and quality of health care, income growth inequality, and educational standards are also used. Examples are access to certain goods (such as the number of refrigerators per 1000 people), or measurement of health such as life expectancy. It is the ease by which people living in a time or place are able to satisfy their needs and/or wants.
There is also the biological standard of living, which pertains to how well the human biological organism fares in its socio-economic environment. It is often measured by the height of a population.
The idea of a 'standard' may be contrasted with the quality of life, which takes into account not only the material standard of living but also other more intangible aspects that make up human life, such as leisure, safety, cultural resources, social life, physical health, environmental quality issues.
