Résumé (anglais)

Little evidence is available to assess the effect of substituting occupation-based income scores for individual incomes before 1940. The example of immigrant assimilation in Canada 1911-1931 reveals differences in the extent and even the direction of assimilation depending on whether income scores are used and how the occupational income score is constructed. Given the increasingly wide use of income scores, we summarize a number of procedures to address the limitations associated with the absence of individual level income variation. An adjustment of conventional income scores for either group earnings differences and/or intertemporal change using summary information for broad groups of occupations reduces the deviation between scores and actual incomes.
