Partial and total displacement migration in Northridge, California : an evaluation of the Roseman theory
In 1971, Roseman proposed that there are two basic types of migration—partial displacement and total displacement migration--which are distinguished in terms of the amount of disruption that a move produces on the weekly activity patterns of migrant households. These two types of migration are said to differ in a number of important respects. It is the purpose of this thesis to evaluate Roseman's theory by testing Northridge samples of his two kinds of migrant for independence in each of six variables. The variables chosen were: (1) distance moved; (2) reasons given for moving; (3) sources of information that led to the new residence; (4) reported annual income; (5) disparity of income reported to mean income of census tract moved into; and (6) reported ages of heads of household. Through the use of the t-test, Chi-square, and the median test, it was found that the two kinds of migrant indeed do differ significantly in terms of distances each moves, reasons given for moving, sources of information, and ages of heads of household, but do not differ in income and income disparity.
