The researchers from the NICHD Early Child Care Research Network report their findings in the July/August 2005 issue of the journal Child Development. They represent the universities of Arkansas (Little Rock), California (Irvine, Riverside and San Diego), London, Michigan, North Carolina (at Chapel Hill and Greensboro), Pittsburgh, Texas (Austin and Dallas), Virginia, Washington, and Wisconsin (Madison), and Harvard University, the NICHD, the Research Triangle Institute, Temple University, and Wellesley College.
To investigate whether the length of time a child's family experiences poverty or the child's age when the family is poor is more important in affecting a child's educational and social competencies, the researchers looked at families in the NICHD Study of Early Child Care. The families studied were either poor throughout their child's early life (from birth to age 9), poor only when the child was under age 3, or only after the child was 4, or never.
"We found that children from families who were poor any time during the early childhood period did not perform as well as those who were never poor," said Marion O'Brien, Ph.D., professor and director of the Family Research Center at the University of North Carolina at Greensboro, one of 26 researchers who participated in the study.
"Parents who were poor provided less stimulating and supportive home environments than those who were never poor, and if families became poor after the child was age 4, the quality of their home environments dropped over time," she said.
The findings contradict other research suggesting that poverty early in a child's life is likely to have particularly serious long-term effects. "We did not find this to be true if the family moved out of poverty later," said Dr. O'Brien. "Instead, we found poverty later in childhood – in this case from age 4 to 9 – was linked to more school and social problems."
The findings suggest, she said, that efforts to help parents of young children move out of poverty are likely to have long-term benefits for children's school performance and social-emotional well being, she said.
