The term “representative bureaucracy” was first given currency in 1949 through Donald Kingsley's book with the same title and since then it has gained popularity through the discussions of a few American political scientists and British sociologists. The underlying concept, however, is still subject to some confusion owing in part to its normative overtones. This paper attempts, in the first place, to analyse some important sources of confusion and, secondly, to show the practical difficulties in the realization of a representative bureaucracy by comparing the social backgrounds of civil servants in different countries.
