The population experienced fluctuations throughout the years, with some periods of slight increase, but the overall trend was downward. The most significant decrease occurred between 2019 and 2020, when the population declined from 176 to 139. This sharp decline may have been influenced by the global COVID-19 pandemic and its associated economic and social impacts.

Based on the national average household size of 2.61 persons, Hargis Heights is estimated to have approximately 52 housing units in 2022. This housing stock, combined with the current population density, suggests a neighborhood primarily composed of single-family homes or small multi-unit dwellings. The current demographic profile indicates that residents now have more space per capita compared to a decade ago.

The lifestyle in Hargis Heights has likely evolved with these demographic changes. Residents may now experience more spacious living conditions and potentially a quieter environment compared to the denser suburban atmosphere of the early 2010s. However, this population decline might have impacted local businesses and community services, potentially reducing the availability of amenities within the immediate neighborhood.

It is important to note that Hargis Heights, as part of the larger Nashville-Davidson metropolitan area, may still benefit from proximity to urban amenities and employment opportunities, despite its own population decrease. The neighborhood's evolution reflects broader trends observed in many American suburbs, where population dynamics can shift significantly over relatively short periods, influencing the area's character and lifestyle.
