Why This Indicator Matters

Young children have specific health and care needs associated with this critical age of development including access to pediatric checkups, immunizations, and quality childcare.1 Young children were undercounted at a higher rate than any other age group in the 2010 Census, and face a similar risk of being undercounted in the upcoming Census.2

Since the U.S. Census Bureau revises their post-2010 estimates each year, the data presented here may differ from previously published estimates.
