U.S. Decennial Census Data

This census is conducted every ten years by the United States Census Bureau to count every person living in the United States, regardless of citizenship status, and to provide an accurate demographic makeup in the country. The data source provides detailed information about the characteristics of the U.S. population at the state level, including age, sex, race and ethnicity, household size, residence in urban or rural areas, etc. For example, from the 2010 Decennial Census, users can access to percentages of population residency and population density (persons per square mile) in urban and rural areas. The 2020 Census was collected during the pandemic, with most households responding online. Besides the variables collected in 2010, users can also access data on same-sex relationships, grandparents as primary caregivers, and more.

The Decennial Census data can be used for a variety of purposes for stakeholders to make informed decisions, including distributing federal funds to state and local governments for programs such as Medicaid, reapportioning seats in the House of Representatives, planning future services and infrastructure, such as healthcare, education, and transportation, as well as emergency response.
