The demographic changes have coincided with fluctuations in median income. The median income peaked in 2021 at $119,296, coinciding with the most diverse year in the dataset. Income levels have generally remained high throughout the period, ranging from the mid-$90,000s to over $100,000, indicating a consistently affluent neighborhood.

The population has shown variability, with no clear linear trend, fluctuating between approximately 1,400 and 2,000 residents over the years. This suggests that while the racial composition is changing, the overall desirability and capacity of the neighborhood have remained relatively stable.

The gradual diversification of Quincy Hollow reflects broader national trends of increasing diversity in suburban areas. Many suburbs across the United States, particularly those near major metropolitan areas, have seen growing minority populations over the past two decades. The pace of change in Quincy Hollow appears to be slower than national averages, which could be attributed to its history as a planned community and its relatively high income levels.

The economic resilience of the neighborhood, maintaining high median incomes despite demographic shifts, is notable. This suggests that the incoming diverse populations are likely of similar socioeconomic status to the existing residents, potentially indicating a pattern of affluent minority families moving into traditionally white, upper-middle-class suburbs.

Quincy Hollow remains a predominantly white, affluent suburb, but shows clear signs of a Transitional Community. The increasing diversity, particularly in Hispanic and Black populations, coupled with stable high incomes, suggests a gradual integration of minority groups into this historically homogeneous neighborhood. This trend, if continued, may lead to a more diverse community in the coming years, potentially shifting towards Moderate Diversity while maintaining its economic prosperity.
