Employing cluster analysis, this article reconsiders a concept formulated by Francis G. Castles that stresses the existence of four families of nations, which markedly differ in respect of public policy‐making. For two policy fields — social and economic policy — the hypothesised families of nations can be shown to exist, and they are quite robust and stable over time. Cluster analysis also reveals different paths towards modernity. On the one hand, there are more state‐oriented versus more market‐oriented models of public policy‐making, on the other, there is a cleavage in public policy‐making between rich countries located at the centre and somewhat poorer countries located at the periphery.
