The most significant income growth occurred between 2018 and 2021, with the median income increasing from $44,938 to $65,454. This rapid increase may indicate an influx of higher-income residents or improved economic opportunities within the area.

The trend of increasing median income in Finleyville likely aligns with broader economic recovery and growth patterns observed in many parts of the United States following the 2008 recession. However, the persistent lack of racial diversity in the community contrasts with national trends towards increasing diversity in many urban and suburban areas.

Based on observed trends, Finleyville is likely to maintain its status as a low diversity community with a strong white majority in the near future. The slight increase in residents identifying as two or more races in 2022 might indicate the beginning of a very gradual shift towards slightly more diversity, but this change is currently too small to suggest a significant demographic transition.

Economically, if the trend of increasing median income continues, Finleyville may experience further economic growth. This could potentially lead to more economic opportunities and possibly attract a more diverse population over time. However, given the strong persistence of the current demographic makeup, any transition towards a moderate diversity category would likely be a long-term process, potentially spanning several decades if it occurs at all.

In conclusion, while Finleyville has experienced significant economic growth over the past decade, its racial composition has remained largely unchanged. The community's future will likely be characterized by continued economic development within the context of a predominantly white population, with the potential for very gradual diversification over an extended period.
