Social mobility is the movement of individuals, families, households, or other categories of people within or between social strata in a society. It is a change in social status relative to others' social location within a given society. ==Definition and typology== Social mobility is defined as movement of individuals, families, households, or other categories of people within or between layers or tiers in an open system of social stratification. Open stratification systems are those in which at least some value is given to achieved status characteristics in a society. The movement can be in a ''downward'' or ''upward'' direction. ''Absolute'' social mobility refers to the overall numbers of people who end up in a different layer of stratification from that of their parents. ''Relative'' social mobility refers to the differences in probability of attaining a certain outcome, regardless of overall structural changes; a society can have high absolute mobility and low relative mobility. The availability of at least some social mobility can be important in providing pathways to greater equality in societies with high social inequality. Mobility is most often quantitatively measured in terms of change in economic mobility such as changes in income or wealth. Occupation is another measure used in researching mobility, which usually involves both quantitative and qualitative analysis of data. Yet other studies may concentrate on social class. Mobility may be ''intragenerational'', within the same generation, or ''intergenerational'', between one or more generations. Intragenerational mobility is less frequent, representing "rags to riches" cases in terms of upward mobility. Intergenerational upward mobility is more common, where children or grandchildren are in economic circumstances better than those of their parents or grandparents. In the U.S.A, this type of mobility is described as a fundamental feature of the "American Dream," even though the United States has less such mobility than almost all other OECD countries.〔http://www.oecd.org/officialdocuments/publicdisplaydocumentpdf/?doclanguage=en&cote=eco/wkp%282009%2948〕
