Research on narrowing the academic achievement gap between lower- and higher-income youth tends to focus on the inputs provided by schools. Little attention, however, is paid to extracurricular activities, both structured and unstructured, even though extracurricular participation and employment can have positive impacts similar to in-school experiences. This brief uses data from the 2012 National Survey of Children's Health to examine involvement in activities among youth ages 12-18 across income categories and metropolitan status in the hopes of informing policy aimed at attenuating inequalities in participation.
