Standard Data Dictionary

StandardDatasetImage.jpg

The Standard Data Dictionary is Prince William County's official demographic dataset. The dataset contains hundreds of demographic variables and geographic identifiers derived from the U.S. Census American Community Survey (ACS) 5-Year Estimates, which are the most accurate and reliable "intercensal" estimates. The Census ACS data values are adjusted to the county's more current (as of the latest 4th quarter) estimates of total population, housing units, and households.

The dataset contains a large amount of information and includes the following attributes: Category, Attribute Name, Value, Units, Percent, Universe, Data Currency, Source, Dataset, Data Table, Margin of Error, Definition/ Description, Methodology, Access, and Notes. For these reasons, the dataset is more than just a table of values; it communicates precisely where the data was drawn from, what it means, where you can access it online, and more.
