Data report: online surveys. Wave 2 & Polish 2021 online survey

The MOBILISE project examines why some people respond to discontent by protesting, others by migrating while yet others stay immobile. It focuses Ukraine, Poland, Morocco and Argentina and migrants from these countries who live in Germany, the United Kingdom and Spain. The first part of this paper reports on the second wave of the panel survey among migrants from Argentina, Poland and Ukraine, and the national population of Argentina and Ukraine. Across target groups, 12 to 21 per cent of wave one respondents completed the second wave.. This is higher than might be expected in the absence of interviewer encouragement or material incentives. Analyses of the results suggest attrition bias on age, education and political interest, but these are modest in size. There is no evidence of attrition bias on Facebook use or migration aspiration. The second part of the paper presents the set-up and results of an online survey among migrants from and nationals in Poland in early 2021. The paper compares the results of the migrant surveys in 2019 and 2021 to find that the composition of the samples obtained are very similar, though the cost per respondent in 2021 was considerably higher. The latter is mostly likely a result of a higher ad budget. The online national sample is higher educated, more interested in politics, more active on Facebook, less often supportive of the ruling party and more often aspires to migrate than the face-to-face sample. This mostly replicates the pattern we found in earlier analyses of the Argentinian and Ukrainian online and face-to-face national surveys.
