The Acklen Avenue Alliance neighborhood in Nashville, Tennessee, has undergone a significant demographic shift from 2013 to 2022. In 2022, the neighborhood exhibited a "White Majority" demographic composition, with 62% of the population identifying as white. This represents a change from a more diverse racial makeup a decade prior. The area has also experienced substantial economic growth, with the median income increasing from $25,358 in 2013 to $56,200 in 2022. The neighborhood's proximity to Vanderbilt University and its combination of historic homes and new developments likely contribute to these demographic and economic changes.

In 2013, the Acklen Avenue Alliance was categorized as a "Moderate Diversity" area, with the population nearly evenly split between Black (49%) and White (45%) residents. Over the decade, the neighborhood transitioned through several categories. From 2013 to 2017, it maintained "Moderate Diversity" with Black and White populations each around 40-50%. In 2018-2019, it shifted towards "White Plurality" as the White population surpassed 50%. From 2020 to 2022, it transitioned to "White Majority" as the White population exceeded 60%. This shift indicates a trend of gentrification, with the Black population decreasing from 49% to 28% over the decade, while the White population increased from 45% to 62%.

The demographic shifts correlate with economic changes. From 2013 to 2022, median income more than doubled from $25,358 to $56,200. Despite significant demographic changes, the overall population remained relatively stable, growing from 830 in 2013 to 872 in 2022. The rapid increase in median income, coupled with the demographic shift towards a White majority, suggests a process of economic gentrification. This likely involves an influx of higher-income White residents, potentially displacing lower-income Black residents.
