Note: *** indicates that differences in means according to naturalisation status are significant to the 1 % level according to the t test, the Mann-Whitney test and Pearson’s chi-squared test, respectively. Pearson’s chi-squared test tests the null hypothesis that the distribution of naturalisation and the categorial variables’ origin, position in the job and firm size are independent
