School-age children need safe, supervised places to learn and grow during non-school hours while their parents and caregivers work. Beyond providing safety and supervision, participation in high-quality school-age child care programs offered before or after school, or during the summer, is associated with positive developmental outcomes for young people. Yet, compared to child care and early education for children ages birth to 5 (and not yet in kindergarten), there has been relatively less nationally representative research on the availability and use of nonparental out-of-school time care for children ages 6 to 12. Based on the current analysis, there were approximately 27.9 million school-aged children in the United States in 2019, representing a substantial group of young people potentially in need of care. This snapshot describes the potential need for out-of-school time care for school-age children using the 2012 and 2019 National Survey of Early Care and Education (NSECE). Given past research has found differences in out-of-school time activity participation by race and ethnic background and income level, the prevalence of out-of-school time care among different demographic groups is also examined. Although the data for this snapshot are from before the COVID-19 pandemic began, which led to widespread disruptions to families' access to child care, the findings provide useful information about differences and declining trends in use of nonparental out-of-school time care arrangements among some subgroups of children that began prior to the pandemic.
