In search of a frame: challenges and opportunities for sampling immigrant minorities.

When it comes to evaluating immigrants' integration, survey data are particularly important. However, the endeavor of surveying immigrant minorities is challenging. This special issue focuses on the possibility of obtaining high-quality cross-country comparable samples of immigrant minorities.

Sampling migrants in six European countries: how to develop a comparative design?

This article discusses the possibilities and constraints of designing an identical or at least comparable sampling strategy across different European countries. It is based on expert reviews from six European Union member states that discuss the possibilities of sampling migrants in their respective countries. The country sample includes two countries from Northern Europe (Sweden, Denmark), two from Continental Europe (Germany, The Netherlands), and two from Southern Europe (Spain, Italy).

Using population registers for migration and integration research: examples from Denmark and Sweden.

The paper starts from the observation that research on immigrants' integration trajectories needs detailed information, both objective and attitudinal, and ideally longitudinal. This study uses the cases of Denmark and Sweden - whose registers produce detailed records about all natives' and immigrants' lives in their host countries - in order to, first, review existing research on immigrants and their integration and, second, discuss the way in which register data are used, their caveats and their potential. The study finds that, in Denmark and Sweden, registers provide systematic objective data which are fully available to researchers and have the potential to help in the collection of high-quality subjective data.
