The population has remained relatively stable, growing slightly from 15,940 in 2013 to 16,267 in 2022, a modest increase of about 2%. This stability suggests that the area has maintained its attractiveness to residents while slowly becoming more diverse.

The demographic trends in Martinsville reflect broader national patterns of increasing diversity, albeit at a slower pace. The high median income and its steady growth align with trends seen in other wealthy suburban areas, particularly those near major metropolitan centers.

The stability of the population, combined with increasing property values (as suggested by the rising median income), indicates that Martinsville remains a desirable location. This could potentially lead to further diversification in the future as more affluent minorities move into the area.

While Martinsville remains a predominantly white, affluent area with low diversity, there are signs of slow but steady demographic changes. These shifts, coupled with the area's economic stability, suggest a gradual transition towards increased diversity, though it may take many more years before reaching a "Moderate Diversity" classification.
