NOTES: Net undercount is the difference between the estimate (A.C.E. or demographic analysis) and the census, divided by the estimate. Minus sign (−) means a net overcount. Population is total population, including household members and group quarters residents.

a In the original A.C.E., children ages 0–17 were a single category.
