        abstract = {Polish self-employed migrants in Berlin differ to a large extent from what could be expected, according to the relevant literature: they seamlessly blend in with the local German population. It seems likely that those who are successful with integrating are more successful in self-employment as well. A survey is used to analyse the relation between ethnic diversity in the social networks of self-employed Poles and their success. Though the sample size is small (12 unique respondents) and the results are not statistically significant, it is in line with the expectation that a social network with a high share of locals positively affects the likelihood of success.},
