Abstract
New family models? New filial and conjugal relations? In the last century both structural and global changes have been vertiginous and have demonstrated that nothing inexorable exists and that everything changes with the passing of time. Or they prove that something may alter in order to preserve its very essence as it seems to be the case of the cell of society itself: the family. In Argentina, our country, Córdoba does not differ from national reality. We wonder in what ways the patterns of reproductive behaviour and the determiners of nuptiality and fecundity in the creation of families have been modified in the last two hundred years. Can we speak about different family patterns? What behaviours have remained stable? This article focuses on the formation of "cordobesas" families in the ligh of some sociodemographic indicators along not only colonial and independent periods in history but also in recent times.
