  • All percentages are weighted; the numbers are unweighted. Because of differences in attrition rates across follow-ups, estimates vary across different points in time. Some children have both chronic conditions and special needs, but they were counted only once for SHCNs; as a consequence, the final estimate for SHCNs appears to be lower than the sum of chronic conditions and special needs.
