Relative deprivation
（重定向自Relative deprivation theory）
Relative deprivation is the lack of resources to sustain the diet, lifestyle, activities and amenities that an individual or group are accustomed to or that are widely encouraged or approved in the society to which they belong. Measuring relative deprivation allows an objective comparison between the situation of the individual or group compared to the rest of society. Relative deprivation may also emphasise the individual experience of discontent when being deprived of something to which one believes oneself to be entitled, however emphasizing the perspective of the individual makes objective measurement problematic.
