Black and Hispanic young children have higher net undercounts than others.

The graph below shows the net undercount rate for all children age 0 to 4 in the 2010 was 4.6 percent.  But for Black Alone or in Combination it was 6.3 percent, and for Hispanics it was 7.5 percent.  These rates are more than twice as high as the estimate for Non-Hispanic White children.

This data indicate that areas with large numbers of black or Hispanic young children should be a high priority for the 2020 Census.  It also means households with young black or Hispanic children should be a high priority for the communications and partnership program of the 2020 Census.
