This brief draws on survey and retrospective calendar data from the 2012 National Survey of Early Care and Education (NSECE) to describe the work schedules of low-income Hispanic parents with young children from birth to age 5 (not yet in kindergarten), and provide comparison data for their non-Hispanic white and black counterparts. We calculate the percentages of low-income Hispanic children with parents working standard weekday, early morning, evening, overnight, and/or weekend hours. We also examine the percentage of children whose parents have short advance notice (one week or less) of their work hours, which has been shown to complicate parents' efforts to arrange child care and maintain family routines. Importantly, we report estimates separately for children in single- and two-parent households, as families' ECE needs, preferences, and options vary depending on the number of parents in the home. We additionally look at differences among Hispanic children by household nativity status. (author abstract)
