This article compares the welfare services for adults with an intellectual disability in three European countries: England, Norway and Sweden. The purpose of the comparison is to develop an understanding of the welfare state and institutional contexts of the country-specific policies and to develop a critical analysis through a comparative method based on selected secondary literature. Typological frameworks of European welfare states are applied as analytic frameworks to enable comparison between the countries. It is argued that there are international policy developments but these are shaped at a national level by different types of welfare states and histories. Through a comparison of similarities and differences, the article suggests that international policy ideas that impact on the lives of people with intellectual disabilities are mediated by different types of welfare states and institutions.
