In which order do Maslow's five classes of needs rank from lowest to highest?

The ranking of Maslow's five classes of needs from lowest to highest is understood as a hierarchy where individuals must satisfy lower-level needs before they can address higher-level needs.

The correct order begins with physiological needs, which are the basic requirements for human survival, such as food, water, and shelter. Once these needs are met, individuals seek safety needs, which include personal security and health. Following safety, social needs emerge, emphasizing the importance of relationships, belonging, and affection from others. After social needs, individuals pursue esteem needs, which involve the quest for self-esteem and the respect of others. Finally, at the top of the hierarchy is self-actualization, where a person strives to realize their full potential and achieve personal growth and fulfillment.

In this context, the order of "physiological - safety - social - esteem - self-actualization" accurately encapsulates the progression of human needs as proposed by Maslow.
