摘要:On the 50th anniversary of the War on Poverty in January 2014, poverty remains a salient policy issue, and dramatic changes in family life have made it even more difficult to design and carry out effective antipoverty policies. I am happy to introduce this issue of Focus, which includes an important essay on the rise and fall of poverty as a policy issue since the declaration of the War on Poverty, and summaries of papers by emerging social science scholars on topics related to family complexity. The set of four family complexity articles is introduced by the conveners of IRP’s Family Complexity, Poverty, and Public Policy conference held in July 2013. The senior scholars’ papers and commentaries from that conference will be published in July 2014 in The ANNALS of the American Academy of Political and Social Science (vol. 654).
