According to data from Destatis (2015a), the share of children (0-to-l 7 year-olds) living in two parent families declined by almost 6 percentage points between 1996 and 2014. This is entirely on account of a drop in the number of children in families with two married parents, which fell by more than 10 percentage points between 1996 and 2014. Over the same period, the share of children living in families with two cohabiting parents more than doubled from 4% to the 9% - mirroring an increase in cohabitation in the adult population (see Box 2.1).
