| Abstract: | The relationship between migration and fertility was explored on the basis of data collected in a 1966 survey conducted in the 9 largest cities of Morocco. Existing contradictory findings suggest the need to specify and analyze the conditions under which fertility differentials by migration status are observed. The 2 theoretically most interesting conditions were considered: the historical context of migration; and the type of migration. A stratified area probability sample was selected with different sampling fractions within each city and city-strata. In each sampled household, 1 married woman under age 50 and 1 50 years and over, as well as single women ranging in age from 15-24, were selected at random and interviewed by female interviewers. The present analysis was limited to data for ever married women under age 50. The following variables were used as controls in the analysis of the relationship between migration status and fertility: the intermediate variable of age at marriage; measures of socioeconomic status; labor force participation of women; and measures of exposure to the modernizing influence of the city. If the 2 conditions of historical context and migration typology had been ignored in the analysis of data for Morocco's cities in 1966, meaningful fertility differentials would not have been evident. It was only after migration typology and historical context were considered that a more noticeable pattern of differential fertility emerged. Migrants of rural or urban origin who moved to the largest cities of Morocco after independence in 1956 had the lowest fertility of any group. The highest fertility was observed for women who moved to these cities before 1956. The fertility of urban natives and of urban migrants who moved before 1956 was between the 2 extreme levels. Controlling for the effects of age at marriage and various socioeconomic factors reduced the fertility differentials but failed to change their pattern. It was hypothesized that the lower fertility of recent migrants may be explained by social mobility. |
