This page is under construction.Detailed data tables of Delaware County demographics are available here and cover a wide range of subjects from income to ancestry.


All of the data found on this page comes from The American Community Survey (ACS), which is an ongoing statistical survey by the U.S. Census bureau. This means that the program is regularly gathering information by sending out surveys year-round to a sample of the population. It collects data that was previously contained only in the long form of the decennial census, such as ancestry, educational attainment, income, language proficiency, migration, disability, employment, and housing characteristics. The data from the surveys is used to estimate the values for the entire population, which is different from a complete count survey like the decennial census.
