The Number of Children in The Population Estimates Program Blended Base Used for Post-2020 Census Estimates Compared to the 2020 Census Count
Since the 1970s, the Census Bureau has produced yearly population estimates for states and counties for the decade following each Decennial Census. The estimates include the number of children (population ages 0 to 17) for states and counties. The estimation method used by the Census Bureau starts with a population base and then adds or […]
Comparing the Accuracy of the 2020 Census Counts to Population Estimates Program Blended Base for Age Groups of Children
Following the 2020 Census, the Census Bureau implemented a new method for developing the population base used for the post-2020 Census estimates (U.S. Census Bureau 2021a). The new method is commonly referred to as the PEP (Population Estimates Program) blended base. The accuracy of the PEP blended base is important for young children because it […]
Analysis of Census Bureau’s August 2022 Differential Privacy Demonstration Product: Implications for Data on Young Children
Executive Summary The U.S. Census Bureau is using a new method called differential privacy (DP) to help protect the confidentiality and privacy of respondents in the 2020 Census. This paper provides some information on how the use of DP in the 2020 Census is likely to impact the accuracy of data for young children (population […]
Analysis of Unified School Districts and Places with Large Errors for the Population Ages 0 to 4 Caused by Application of Differential Privacy
In my analysis of the DP Demonstration Product released by the Census Bureau on August 25, 2022 (O’Hare 2022) I found many Unified School Districts and Places[1] where DP introduced large errors for the population ages 0 to 4. This paper focuses on those units that have an absolute percent error of 25 percent or more and those […]
A More Meaningful Comparison of the 2010 and 2020 Census Estimates of Net Undercoverage of Young Children
The Census Bureau recently released 2020 Census Demographic Analysis (DA) estimates of the net undercount of young children (ages 0 to 4). Jensen (2022) reported a net undercount of -5.4 percent for this age group. Comparisons with DA estimates from 2010 indicate an increase in net undercoverage of 0.8 percentage points (4.6 percent compared with 5.4 percent). Jensen […]

Counting Young Children in the U.S. Census – Important Differences Between 2010 and 2020
This report was originally posted by The Leadership Conference on Civil and Human Rights. The high net undercount of young children has been an on-going problem in the U.S . Decennial Census. Data released by the Census Bureau last month showed young children (ages 0 to 4) had the highest net undercount of any age group, as they […]
New Census Bureau Data Show Young Children Have a High Net Undercount in the 2020 Census
On March 10, 2022, the U.S. Census Bureau released some of the primary metrics needed to evaluate the quality of the 2020 Census (U.S. Census Bureau 2022). Specifically, the Census Bureau released data from Post-Enumeration Survey (PES) and limited data from the 2020 Census that could be compared to the Demographic Analysis (DA) estimates released […]
Many Young Children of Color are Clustered in Census Tracts Where 2020 Census Self-Response Rates are Likely to be Problematic
The best data on the quality of 2020 Census count of young children will not be available until the fall of 2022. That is when the Census Bureau is likely to release 2020 Census counts for the population ages 0 to 4 that can be compared to the Census Bureau’s Demographic Analysis estimates to calculate […]
