CPHD Population and Demographic Estimates
The CPHD Population and Demographic Estimates (PDE) are designed to provide demographic profiles for Arlington’s civic associations, which do not align to U.S. Census Bureau geographies. The PDE enhances CPHD’s population estimates, which are found in the annual Profile, by applying U.S. Census Bureau American Community Survey estimates at the housing unit level and summarizing population for civic associations.

Feedback
Thanks to the community for taking the time to provide feedback on the 2023 Beta version of the dashboard. Based on the comments received and available data, we were able to update the 2024 version with housing unit type and percent of Limited English Households. We have also added a definitions document linked above.
We continue to welcome feedback and invite the community to provide feedback online.

Method
Using the Master Housing Unit Database (January 2024), estimates are derived for total households, household population, and total population. Details about this methodology can be found in CPHD’s 2020 Population Estimation Methodology. Each housing unit is then assigned demographics based on the Census Block Group in which it is located. The assignment is percentage based. For example, if a housing unit falls in a Block Group with 5% of the population under the age of 5 years, then that housing unit is coded to have 5% of residents under the age of 5. Housing units are then grouped together and summarized for meaningful geographies.
Use and Reliability
The PDE is intended to provide a demographic snapshot for Arlington’s civic associations. It is not intended to be used at the housing unit level. The PDEs are produced using American Community Survey (ACS) estimates. The ACS is administered to a sample of the population and therefore contains margins of error (MOE). Exercise caution when PDEs show small portions of the population for any one geographic area or variable. In some cases, estimates may be unreliable due to large MOEs. However, there is value in comparing the distribution within the demographic variables.
