Data for 2020 are based on the experimental estimates from the 1-year American Community Survey released by the Census Bureau instead of the traditional 1-year estimates. For more information, visit the 2020 ACS 1-Year Experimental Data Release page.

Single-year estimates from the American Community Survey (ACS) are "period" estimates derived from a data sample collected over a period of time, as opposed to "point-in-time" estimates such as those from past decennial censuses. ACS single-year estimates include data collected over a 12-month period; explicitly the calendar year (e.g., the 2015 ACS covers the period from January 2015 through December 2015).

Please see the ACS handbook (Section 3, "Understanding and Using ACS Single-Year and Multiyear Estimates" p. 13) for a comprehensive set of details and clarifications.
