Maslows hierarchy of needs is a motivational theory in psychology that comprises a five-tier model of human needs, often depicted as hierarchical levels within a pyramid. The five levels of the hierarchy are:

1. Physiological Needs: These are the most basic needs for human survival, including food, water, clothing, shelter, and sleep. They must be satisfied in order for individuals to address more complex needs like mental and physical health, relationships, sobriety, long-term housing, and employment.

2. Safety Needs: Once physiological needs are met, individuals move to the next tier of safety needs. Here, they need to feel safe and secure, both physically and emotionally. This includes job security, financial stability, and living in a safe neighborhood.

3. Love/Belonging Needs: The third level of Maslows hierarchy of needs involves having a sense of belonging and feeling loved. This includes the need for friendship, intimacy, and family.

4. Esteem Needs: Esteem needs refer to the need for self-esteem and the esteem of others. This includes the need for respect, recognition, and achievement.

5. Self-Actualization Needs: The highest level of Maslows hierarchy of needs is self-actualization, which refers to the need for personal growth, fulfillment, and the realization of ones full potential. This includes the need for creativity, problem-solving, and personal development.

It is important to note that Maslow suggested that "higher" needs can begin to develop even when "lower" needs are not fully satisfied, and that the order of needs might be flexible based on external circumstances or individual differences.
