Originally emerging from environmental policy, the concept of sustainability has been gaining significance in German family policy since the turn of the millennium. In contrast to the apparent interest of family policy actors in linking the topics of "family policy" and "sustainability," the fact remains that the postulate of a "sustainable family policy" has so far been based on only a very rudimentary theoretical conception. This volume fills that gap and offers both the professional community and political-administrative decision-makers a proposal for an indicator-based sustainability concept for family policy.
