This paper examines the association of education and family forms based on data of the German microcensus 1996–2012. The investigation shows that highly educated women in western Germany had a higher probability of living in a nonmarital instead of a marital union. With an increase in the share of nonmarital births, the association has reversed. Likewise, the highly educated couples were initially the vanguards of living in nonmarital unions with children, but they are nowadays the least likely to do so. Patterns differ between eastern and western Germany, though.
