Demand mobility is a form of social mobility more according to demand in changing business and global environment.
Demand mobility takes place over time and is not caused by individuals ascending or descending in class or status, but by changes in the occupational structure of the economy.
Demand mobility results from there being greater demand for some kinds of labour and a shrinking demand for others and not from the openness of the society.
In modern economies there is a great amount of demand mobility among occupations. Demand mobility is occupation movement due to changing business and global environment.
In a situation of high demand mobility, with little openness, one might find that workers occupy the same relative positions in social and economic position as their parents although performing quite different work.
Values, Demand and Social Mobility
Abstract: If industrial societies in fact institutionalize universalistic-achievement values in the area of social mobility to a greater extent than pre-industrial societies, one would hypothesize that when inter-societal differences in occupational demand are held constant, industrial societies should still exhibit more mobility than pre-industrial societies. Tested with mobility data at the elite level in industrial and pre-industrial societies, this hypothesis is not strongly supported. Greater "openness" of industrial societies may be due wholly to quantitative occupational demand, rather than to values and norms of a universalistic-achievement type.
