The continuing decline in prime-age employment interacts with ongoing changes in the structure and composition of low-income families. The relevant trends here include (a) declining marriage rates and increasing cohabitation, (b) increases in nonmarital births and multi-partner fertility, and (c) rising noncustodial parenthood (especially for fathers). These developments all work to weaken the “family safety net” for poor children. In a precarious labor market, a second parent provides backup in difficult times (e.g., extra income, childcare), thus reducing the risks of poverty. The family safety net is in this sense weakening just as the labor market is becoming more precarious. Moreover, because some programs (e.g., EITC) provide higher benefits for custodial parents, the rise of noncustodial parenting undermines the capacity of the formal safety net to step in as the family safety net weakens. These and related changes in family structure have prompted a spate of policy proposals, some involving safety net reforms that accommodate the new family forms (e.g., incentivizing noncustodial parents to comply with child-support orders), and others addressing the underlying institutional changes themselves (e.g., increasing the availability of long-acting reversible contraceptives). The charge of the Family RG is to evaluate these proposals and to better understand how the safety net is adapting to changes in family structure. The following projects are a sampling of the research underway within this RG.

A new round of Fragile Families data collection: An initiative to update the Fragile Families Study is underway, with a focus on adding administrative records, metabolic and immune markers, and measures of methylation.

Income and the developing brain: Does income support for families affect the brain function and development of infants? A new experiment will reveal all.

Measuring family complexity in the AOS: Will the American Opportunity Study (AOS) capture the rise of ever more complicated family forms? By linking tax, census, and birth records, the AOS should be up to the task.
