In many studies, the population is divided into a number of social status groups 1 or into socioeconomic groups 1 according to occupation, income, education or similar indices of economic status. The term social class 2 has a sociological connotation which is only approximated by the type of grouping generally used in demographic work. The division of society into a number of such groups is called social stratification 3. Movement between different social status groups is called social mobility 4; a distinction is made between upward mobility 5 and downward mobility 6 in the social hierarchy. The mobility of children with respect to their parents’ social class is called inter-generational social mobility 7.
