In Maslow's hierarchy of needs, which level has the smallest absolute size of travel demand?

In Maslow's hierarchy of needs, the smaller level of travel needs is the physiological needs hierarchy.

Maslow's hierarchy of needs theory divides needs into five categories, from low to high, namely physiological needs, safety needs, social needs, esteem needs and self-actualization needs. Physiological needs refer to people's pursuit of basic survival needs such as food, water, air, housing, etc., while tourism demand is only a consumption behavior with a relatively small scale. It can be said that travel demand is part of the physiological needs hierarchy in Maslow's hierarchy of needs, and its absolute scale is relatively small.
