This article examines how friends' involvement in crime influences such involvement in those around them, as offenders or victims, and the extent to which such friendship effects vary with contact frequency, friendship intimacy, and geographical proximity. To test our hypotheses we used four waves from the Dutch panel survey CrimeNL, which includes ego-centered network measures in each wave for respondents aged between 16 and 45. To test our hypotheses, fixed-effects panel models were employed.

We examined ethnic diversity effects on intra- and inter-ethnic contacts in the neighborhood, respectively on opposition to ethnic in- and out-group neighbors.

Up till now, no study satisfactorily addressed the effect of social mobility on antagonistic attitudes toward ethnic minorities. In this contribution, we investigate the effect of educational and class intergenerational mobility on ethnic stereotypes, ethnic threat, and opposition to ethnic intermarriage by using diagonal mobility models. We test several hypotheses derived from ethnic competition theory and socialization theory with data from the Social and Cultural Developments in The Netherlands surveys (SOCON, waves 1995, 2000, and 2005) and The Netherlands Kinship and Panel Study (NKPS, wave 2002).
