Relative deprivation is the thesis that people's subjective feelings of deprivation, discontent, or grievance are not absolute or based on an objective standard of poverty or need, but rather are relative to their assessment of themselves and their situation in comparison with others around them, particularly those they perceive as being more privileged or having more of what they desire. This feeling of being disadvantaged can arise even when one's basic needs are met, if one believes they are unfairly lacking in comparison to a relevant reference group or societal standards. The experience of relative deprivation can be a significant factor in social unrest, the formation of social movements, and the expression of social discontent, as people strive to achieve what they perceive as equitable or just in relation to others.
