Homogeneity and smallness: Dahl and Tufte revisited

In their well-known volume on 'Size and Democracy' (1973), Robert Dahl and Edward Tufte argue that small units are likely to be more homogeneous, wher eas larger units are likely to exhibit more diversity. This study of the mi crostates of the world and of selected control groups of states supports th is view only in part. In terms of attitudinal diversity, smaller units are indeed more homogeneous. In terms of ethnic and religious diversity, howeve r, no significant differences emerge between small states and large states. This suggests that categoric differences are transformed in larger units t o a greater extent into attitudinal differences. Bearing in mind that most microstates are island states, the capacity of microstates to manage ethnic diversity may in several cases be due to the intimacy of island communitie s which binds members together in mutual solidarity.
