This is Maslow's hierarchy of needs.

This image shows a common interpretation of Maslow's hierarchy of need. It is often portrayed like this pyramid with the most essential and important needs at the bottom and built up getting smaller with the smallest area at the top which shows the needs for self actualisation. The idea is that, like a pyramid each layer cannot exist without the support of the layer before. So before people can consider purchasing luxuries like magazines, they must achieve a sense of safety, love and belonging to reach the next level of needs. Magazines are categorised between Esteem and Self-Actualization because some people need magazines to feel good about themselves but they are considered a luxury which is not essential to survival.
