 In the words of the report, "The former (immigrants) were from the most progressive sections of Europe and assimilated quickly... On the other hand, the new immigrants have come from the less progressive countries of Europe and congregated separately from native Americans and the older immigrants to such an extent that assimilation has been slow".In reaching this conclusion the Commission made distinctions between 'old ' and more recent 'new' immigrants.The report favoured 'old' immigrants from North and Western Europe and opposed 'new' immigrants from Eastern and Southern Europe and Asia.
