What Past Research Tells Us About How to Prepare for the 2030 U.S. Census Count of Young Children
Probably the most important point in this paper is made in Figure 1 which shows a steady increase in the undercount of young children since 1980.

The Net Coverage of Children Ages 5 to 9 in the U.S. Census
This study examines subnational coverage for the population ages 5 to 9 and compares census coverage of children ages 0 to 4 to those ages 5 to 9. Young children (ages 0 to 4) have higher net undercount rates than children ages 5 to 9, and the pattern is pervasive and long standing. The pattern […]
Counties Where the Coverage for Young Children Deteriorated Between 2010 and 2020
The undercount of young children is one of the most vexing problems faced by the U.S. Census Bureau. The undercount rate for young children (ages 0 to 4) was not only high (5.4 percent) in the 2020 Census, but it has been increasing in every Census since 1980 when it was 1.4 percent.
