New TNSDC Dashboard Unlocks Population Change Trends Across Tennessee

The TNSDC County Population Estimates and Components of Change Dashboard is designed to provide county- and regional-level population insights from 2020 through the latest year in the estimate series. Data about population and components of change are included, along with regional and state-level tallies of key performance indicators.

The new data visualization reports current population levels and explains factors driving population increases and decreases across counties and regions of the state.

In an effort to make the latest population estimates more accessible to local officials, business leaders, and the public, on Oct. 18 the Tennessee State Data Center launched a new interactive dashboard.

The dashboard details county-level population trends for the state’s 95 counties from July 1, 2020 to July 1, 2022 and will be updated throughout the decade as new information becomes available. It also delves into the three drivers of population change: births, deaths and net migration.

Data shown in the dashboard are from the annual population estimates series released by the U.S. Census Bureau each March.

For more advanced analysis, the site also includes several multi-county classifications that can provide insights into the state’s evolving population dynamics at the regional-level. For instance, the dashboard can be used to measure population growth rates across urban and rural counties or compare drivers of population change across the state’s nine Development Districts.

These classifications also include the recently published Metropolitan Statistical Areas, in addition to the aforementioned Development Districts and urban/rural county designations from the Tennessee Department of Economic and Community Development.

Other Key Features

Some additional features unique to the TNSDC population estimates are:

  • Interactive map showing the patterns of one-year population change
  • Table and chart showing the fastest-growing counties in each vintage year
  • Breakdown of household and group quarters population

Components of Population Change Tab
