MTNV News - Children who grow up in urban counties with high upward mobility exhibit fewer behavioral problems and perform better on cognitive tests, according to a study led by Princeton University.
This question is what motivated McLanahan and her collaborators, which include lead author Louis Donnelly, Princeton University; Irv Garfinkel, Columbia University; Jeanne Brooks-Gunn, Columbia University; Brandon Wagner, Texas Tech University; and Sarah James, Princeton University.
For their analyses, the researchers looked at 4,226 children from 562 U.S. counties whose developmental outcomes were assessed at approximately ages 3, 5 and 9 years old. The researchers divided these children into low- and high-income groups based on household income at birth. Children from low-income families were born in households earning below the national median household income (mean of $18,282), while children from high-income families were born in families earning above the national median (mean of $73,762).
