The question of the unity of the family models in the Mediterranean has been the subject of much debate in the field of generations history. Some researchers have put forward the much disputed hypothesis of a past unity in the Mediterranean area in relation to marriage and the family. In modern times, however, we are dealing with very heterogeneous situations in this area. A priori , the populations on the different shores of the Mediterranean do not have much in common, with diversified Western family models on one side, and a very specific Arab-Muslim family model on the other. Although different on both sides of the Mediterranean, family models have nevertheless undergone profound changes over the last 70 years: some discuss a “marriage revolution” for the populations of the Southern and Eastern shores, others a second demographic transition in the European countries. In the same way that researchers envisage a convergence of family models in the world towards the Western family model could there be a convergence of Mediterranean family models due to these contemporary family changes? Without directly answering this question, this chapter will attempt to provide some food for thought. Therefore, among the many possible elements for analysing family models, we decided to focus on the formation and dissolution of marriages. We will present the evolution of demographic indicators relating to these two phenomena, starting with marriage and divorce rates, followed by indicators relating to age at marriage and the significance of permanent celibacy. Unlike, the other demographic phenomena, we were unable to use the large international databases to study all the Mediterranean countries since 1950 for these family formation and dissolution related topics. We had to instead collate data from different data providers to create long series.
