Maslow’s Hierarchy of Needs

Abraham Maslow’s hierarchy of needs lays down five fundamental needs and their hierarchical nature. According to the theory, the lower the needs the more fundamental they are and people will only move to higher needs once lower needs are satisfied. The needs are as follows:

Physiological needs - These needs are for sustenance and include health, food and sleep.
Safety needs - These needs include putting a roof over our heads and protecting ourselves from danger.
Belonging needs - These needs include love, affection, kinship and being a part of groups whether in society or in the workplace.
Esteem needs - These needs are an extension of the belonging needs and are for a higher position within a group so that people respect us.
Self actualization needs - These needs include realizing our potential and achieving what we are capable of achieving.
