Challenging knowledge production on migration with statactivism: the category ‘migration background’ and some destabilizations

'Migration background' has been an official category of population statistics in Germany since 2006 and has become an integral part of knowledge production about Germany as an immigration country. However, 'migration background' is not only a way of constructing 'migrant' and 'native' populations; it is also employed as a marker of ethnic inequality and often differentiated into subgroups to stand for national links or ethnic descent. I reflect on these observations as utterances of methodological nationalism inscribed into data practices and (non)knowledge production in migration research. I link them to ideas about statactivism (Bruno et al. 2014. "Statactivism." Partezipatione & Conflitto 7 (2): 198–220) as a means of intervention. I give some examples of how I have tried to destabilize the usual (non)knowledge production in migration research and reflect on the possibilities for individual researchers to do so. My ethnographic analysis is based on a close reading of national statistical reports, fieldwork in statistical offices, participatory observations in workshops, informal and formal interviews, and my own involvement in (non)knowledge production.
