Categorical and spatial interlinkages within the European migration policy mix

This article analyses the categorical and spatial linkages within migration policy areas across 31 European countries from 1990 to 2020, examining over 5000 migration policy changes. It reveals distinct patterns of policy diffusion across space and contrasting trends between different migration policy areas. While migrant admission policies have experienced a trend towards liberalisation over the past three decades, border and return policies have become more restrictive. The research identifies spatial policy dependencies primarily in border enforcement, with some presence in admission, integration, and return policies. The findings underscore the structured nature of the European migration policy mix and contribute to a deeper understanding of the complexities and interdependencies within migration governance.
