The Population Association of America, a COSSA governing member, and the Population Reference Bureau, also a COSSA member, held a congressional briefing on April 17 called “The Vow Factor: Marriage, Divorce and Family Formation & their Impact on Health and Well-Being.” COSSA was a co-sponsor of the briefing. Moderated by Robert Moffitt of Johns Hopkins University, the briefing featured presentations on trends and consequences of changes in marriage and parenthood. Andrew J. Cherlin, Johns Hopkins University, gave a presentation on the education-based gap in the marriage rate. Lisa Berkman, Harvard Center for Population and Development Studies, discussed how single motherhood and maternity leave polices affect women’s health much later in life. The final speaker, Elizabeth Peters, Urban Institute, spoke about incentives for couples to marry and father involvement. A video recording of the presentations will be posted on the Population Reference Bureau’s website.
