The release of formal restrictions on the free movement of Central and East Europeans that started with the end of the Cold War have led to new migration flows in Europe. Although recent years have shown a remarkable growth in the number of surveys carried out among migrants from former communist countries, these surveys tend to focus on topics such as job history, integration in the host country, and bonds with the country of origin. Insofar exchanges with family members are addressed, they tend to be about remittances to and frequency of contact with “the” family in the country that has been left. Information on exchanges of money, practical support, and emotional support with individual family members, background information on the family of origin, espoused family obligations, and marital and parenthood histories is not included in those surveys. That is why a new survey using the GGS questionnaire among 1000 Polish migrants in the Netherlands will be carried out. This data can be matched with GGS data from the countries of origin and with Dutch GGS data, enabling the unravelling of policy, economic, and contextual influences. Population registers will be the sampling frame. The first wave of data collection will start in autumn of 2014 and will be executed with the use of mixed mode design (web-based interviews, telephone interviews and face-to-face interviews). Web-based interviews will be the primary mode of data collection three years later.
