The U.S. Census Bureau released on December 10 estimates from the 2015-2019 five-year American Community Survey (ACS). The ACS is an annual nationwide survey of approximately 3.5 million households that collects data about the demographic, housing, economic, and commuting characteristics of the U.S population. The Census Bureau combines 5 years of data to create a sample large enough to calculate estimates for all geographic locations, including rural locations, and for areas as small as census tracts.
The press kit with information about the release is at: https://www.census.gov/newsroom/press-kits/2020/acs-5-year.html
The full range of ACS 5-year estimates is available online at: http://data.census.gov/
