Basic needs in the context of "Global poverty"

Poverty is a state or condition in which an individual lacks the financial resources and essentials for a basic standard of living. Poverty can have diverse environmental, legal, social, economic, and political causes and effects. When evaluating poverty in statistics or economics there are two main measures: absolute poverty which compares income against the amount needed to meet basic personal needs, such as food, clothing, and shelter; secondly, relative poverty measures when a person cannot meet a minimum level of living standards, compared to others in the same time and place. The definition of relative poverty varies from one country to another, or from one society to another.

Statistically, as of 2019, most of the world's population live in poverty: in PPP dollars, 85% of people live on less than $30 per day, two-thirds live on less than $10 per day, and 10% live on less than $1.90 per day. According to the World Bank Group in 2020, more than 40% of the poor live in conflict-affected countries. Even when countries experience economic development, the poorest citizens of middle-income countries frequently do not gain an adequate share of their countries' increased wealth to leave poverty. Governments and non-governmental organizations have experimented with a number of different policies and programs for poverty alleviation, such as electrification in rural areas or housing first policies in urban areas. The international policy frameworks for poverty alleviation, established by the United Nations in 2015, are summarized in Sustainable Development Goal 1: "No Poverty".

Welfare spending is a type of government support intended to ensure that members of a society can meet basic human needs such as food and shelter. Social security may either be synonymous with welfare, or refer specifically to social insurance programs which provide support only to those who have previously contributed (e.g. pensions), as opposed to social assistance programs which provide support on the basis of need alone (e.g. most disability benefits). The International Labour Organization defines social security as covering support for those in old age, support for the maintenance of children, medical treatment, parental and sick leave, unemployment and disability benefits, and support for sufferers of occupational injury.

More broadly, welfare may also encompass efforts to provide a basic level of well-being through subsidized social services such as healthcare, education, infrastructure, vocational training, and public housing. In a welfare state, the state assumes responsibility for the health, education, infrastructure and welfare of society, providing a range of social services such as those described.

A need is a deficiency at a point of time and in a given context. Needs are distinguished from wants. In the case of a need, a deficiency causes a clear adverse outcome: a dysfunction or death. In other words, a need is something required for a safe, stable and healthy life (e.g. air, water, food, land, shelter) while a want is a desire, wish or aspiration. When needs or wants are backed by purchasing power, they have the potential to become economic demands.

Basic needs such as air, water, food and protection from environmental dangers are necessary for an organism to live. In addition to basic needs, humans also have needs of a social or societal nature such as the human need for purpose, to socialize, to belong to a family or community or other group. Needs can be objective and physical, such as the need for food, or psychical and subjective, such as the need for self-esteem. Understanding both kinds of "unmet needs" is improved by considering the social context of their not being fulfilled.

Maslow's hierarchy of needs is a conceptualisation of the needs (or goals) that motivate human behaviour, which was proposed by the American psychologist Abraham Maslow. According to Maslow's original formulation, there are five sets of basic needs that are related to each other in a hierarchy of prepotency (or strength). Typically, the hierarchy is depicted in the form of a pyramid although Maslow himself was not responsible for the iconic diagram. The pyramid begins at the bottom with physiological needs (the most prepotent of all) and culminates at the top with self-actualization needs. In his later writings, Maslow added a sixth level of "meta-needs" and metamotivation.

The hierarchy of needs developed by Maslow is one of his most enduring contributions to psychology. The hierarchy of needs remains a popular framework and tool in higher education, business and management training, sociology research, healthcare, counselling and social work. Although widely used and researched, the hierarchy of needs has been criticized for its lack of conclusive supporting evidence and its validity remains contested.

Social work is an academic discipline and practice-based profession concerned with meeting the basic needs of individuals, families, groups, communities, and society as a whole to enhance their individual and collective well-being. Social work practice draws from liberal arts, social science, and interdisciplinary areas such as psychology, sociology, health, political science, community development, law, and economics to engage with systems and policies, conduct assessments, develop interventions, and enhance social functioning and responsibility. The ultimate goals of social work include the improvement of people's lives, alleviation of biopsychosocial concerns, empowerment of individuals and communities, and the achievement of social justice.

Social work practice is often divided into three levels. Micro-work involves working directly with individuals and families, such as providing individual counseling/therapy or assisting a family in accessing services. Mezzo-work involves working with groups and communities, such as conducting group therapy or providing services for community agencies. Macro-work involves fostering change on a larger scale through advocacy, social policy, research development, non-profit and public service administration, or working with government agencies. Starting in the 1960s, a few universities began social work management programmes, to prepare students for the management of social and human service organizations, in addition to classical social work education.
