social pyramid

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.
