409:, Garfinkel, and Mincy summarized in 2010 that the FFCWS had four major findings. Firstly, despite earlier conceptions, a large majority of unmarried parents had intimate and loving relationships when their children were born. Over 50% of the unwed couples surveyed in the baseline were living together, and another 36% were dating each other. Secondly, unmarried parents faced numerous challenges regarding career opportunities, family life, and child rearing. Unmarried mothers were on average six years younger than married mothers but were three times more likely to have had another child with another partner. The presence of multiple father figures inside and outside the family increased the likelihood of significant social tensions. In addition, unwed parents reported lower incomes, poorer health, and higher rates of substance abuse. Unmarried fathers were five times more likely to have a prison record, and

bonds may have been fragile. While, in the 1990s, it was known that children living with single mothers after a divorce fared worse than children living in two-parent married households, until the FFCWS, little data was available about children born to unmarried parents – a rapidly growing demographic at the time. The FFCWS is a critical source of data on the wellbeing of children born to unmarried parents, parents’ relationships with each other, father involvement, and how parents’ roles have changed over time. The FFCWS aims to better understand the underlying causes of social problems associated with unmarried families and study the impact of policies on family formation and child development.

The interviewer also gathered observational data on the home environment, the appearance and behaviors of the family, and the neighborhood. In 15 of the 20 cities, the non-familial child care setting--a child care center or an informal child care arrangement--was also observed, and a caretaker at these institutions completed a survey.
