About the Talk

This presentation provides basic data about the net undercount of young children in the U.S. Decennial Census. Results of demographic analysis show that young children (under age 5) had a net undercount rate of 4.6 percent in the 2010 Decennial Census which amounts to a net undercount of almost one million persons age 0-4. The net undercount rate for the population age 0 to 4 is more than twice as high as any other age group. Moreover, the net undercount rate for young black and young Hispanic children is significantly higher than the total undercount rate for this age group. Prior to the 1980 Census, the net undercount rates of young children and adults were both falling in a similar pattern. But since1980 the net undercount rate for young children has increased steadily while that for adults has declined. A few ideas about why young children experience high and increasing net undercount rates are explored, but there is very little evidence on the question of why young children have high undercount rates.
