The increasing median income in Granville aligns with broader national economic growth trends over the past decade. However, the lack of significant racial diversification contrasts with many urban and suburban areas in the United States that have experienced increasing diversity during the same period.

Based on observed trends, Granville is likely to remain a low diversity community in the near future, with a continued white majority. The small multiracial presence suggests potential for gradual diversification over time.

Economically, if current trends persist, the median income may stabilize or slightly increase, potentially reaching $65,000-$70,000 in the coming years. The declining population trend is a concern and could impact future economic growth if it continues.

While Granville is expected to remain in the low diversity category for the foreseeable future, it may be slowly progressing towards becoming a transitional community. This transition would likely take many years and depend on factors such as economic opportunities, housing availability, and broader regional demographic shifts.

In conclusion, Granville shows signs of economic progress, but its demographic composition remains largely unchanged. The community's future will likely depend on its ability to attract and retain residents while potentially accommodating a slightly more diverse population over time.
