Maps showing more detailed subcounty population change between decades aren’t very common because revisions Census Bureau’s “tracts” prevent direct comparison. Learn how we produced a nationwide made showing tract-level change last decade.


A new interactive map shows the change in population between 2010 and 2020 for each of the country’s 85,000 census tracts. The new higher resolution map adds detail to a decade of population change across the US. Explore the map and a list of the country’s fastest-growing Census Tracts!


Did Nashville lose population last year? 2021 Population Estimate data from the US Census Bureau show that Davidson County, which is centered in fast-growing Middle Tennessee, ceded some of the 90,000 people it gained between 2010 and 2020. We take a close look at the numbers.
