M, mean; SD, standard deviation, and n, sample size. The frequencies of demographic categories do not necessarily sum to the total N for that column due to a small percentage of participants having missing data on that variable.

Children were classified as Multiracial if caregivers indicated the child belonged to more than one racial group.
