Family change across societies is a complex issue that raised considerable debates throughout the 1950s and 1960s. Particular attention was given at the time to the unequal pace of family change according to countries or regions in the world, with a hypothesized similar turn to the dominance of the nuclear family in all national contexts, Western or non- Western (e.g., Goode 1963). Since then, family sociology has rebuffed the nuclearization thesis and has, to the contrary, stressed historical trends of family pluralization away from the nuclear family that are present in all Western nations (Lesthaeghe 1995)
