100 Years Population
Every 10 years, the U.S. Census Bureau conducts the Decennial Census. This is a count of all inhabitants in the United States. Required by the U.S. Constitution, it was first conducted in 1790. Over the decades, the Decennial Census has seen many changes. Most recently, the Census Bureau created the option to respond online.
To see the self-response rate (how many responded online or by phone/mail) for your county, visit the 2020 Census Response Rate Map at:
The official population counts are from the Decennial Census or the Census Bureau’s population estimates.
(While population data are available from the American Community Survey, they are NOT the official population figures.) To find out more about the history and changes in the Decennial Census, go to: https://www.census.gov/history/www/through_the_decades/overview/
