This study tested if intergenerational differences in attitudes toward immigration in Sweden exist due to different early life socialization experiences across generations with cohort analysis. Also, if shock effects which are defined as large scale shifts in society affected different age-groups differently? As socioeconomic status was positively related to both proimmigration attitudes and age, age could be excluded from the model assuming aging affected attitudes only indirectly due to increased financial security, this avoided collinearity between age, period and cohort. Assuming that aging does not affect attitudes toward immigration the conclusion was made that intergenerational differences in attitudes exist due to a difference in early life socialization across generations. Observing the trends of different age-groups between 2002 and 2016 a pattern emerged where shock effects like the refugee crisis in 2015 seemed to affect all cohorts with similar force contrary to prior research and the impressionable years and later-life decline models.
