Joelton Heights, a neighborhood in Nashville, Tennessee, currently exemplifies a Low Diversity community with a White Majority. As of 2022, the neighborhood has a population of 243 and a median income of $57,423. The neighborhood has experienced demographic shifts over the past decade, particularly in recent years, suggesting it may be transitioning towards a more diverse community composition.

From 2013 to 2019, Joelton Heights consistently maintained a White Majority status, with the white population comprising over 85% of residents. Starting in 2020, a Transitional Community trend began. The percentage of residents identifying as two or more races increased from 2% in 2017 to 6% in 2020. The Hispanic population grew to 13% in 2021 and 17% in 2022. This shift suggests a trend towards increasing diversity, though the community still falls under the Low Diversity category due to the white population remaining at 78% in 2022.

The demographic shifts in Joelton Heights correlate with changes in median income. From 2013 to 2019, the median income fluctuated but generally remained above $65,000, peaking at $73,299 in 2016. Coinciding with the increase in diversity from 2020 onwards, there was a drop in median income to $57,423 in 2020, a level which persisted through 2022. This decline in median income as the community becomes more diverse could indicate changing economic dynamics within the neighborhood.
