The MOBILISE project examines why some people respond to discontent by protesting, others by migrating while yet others stay immobile. It focuses on four countries that have seen outmigration and protest in recent year (Ukraine, Poland, Morocco and Argentina) and migrants from these countries who live in Germany, the United Kingdom and Spain. The main body of MOBILISE survey data are nationally representative face-to-face surveys in Ukraine, Poland, Morocco and Argentina. As these surveys are unable to capture (current) migrants from these countries – a group that is crucial to answering the MOBILISE research question – MOBILISE employs a migrant survey targeted at three destination countries; Germany, the UK and Spain. MOBILISE migrant surveys were closely oriented to the national surveys in order to achieve the longitudinal nature of the data. All of the surveys thoroughly ask for political views and beliefs as well as socio economic background, the reasons and motivations to (or not) migrate and the reason to (or not) protest. The migrant survey was run online. We also ran two supplementary online national surveys targeting the general population in Ukraine and Argentina. All MOBILISE national and migrant surveys are set-up as a two wave panel. The first wave of data collection for the migrant and national survey started in September 2019 and finished in March 2020. The second wave started between December 2020 and December 2021. This data deposit contains wave one and two of the migrant and national online surveys (the nationally representative surveys are deposited separately).
