The economic changes appear to correlate with the gradual increase in diversity. As the community has become slightly more diverse, there has been a general upward trend in median income, suggesting that the influx of new residents may be contributing positively to the local economy.

The trends observed in Pen Argyl align with broader national patterns of increasing diversity in smaller communities and suburban areas. The gradual increase in Hispanic population, in particular, reflects wider demographic shifts seen across many parts of the United States.

Based on the observed trends, Pen Argyl is likely to continue its slow transition towards greater diversity over the coming years. While it may remain in the "Low Diversity" category in the near term, there is a possibility it could transition into a "Transitional Community" category within the next decade if current trends persist.

Economically, the area seems poised for continued modest growth, barring any significant external economic shocks. The correlation between increasing diversity and rising median incomes suggests that this demographic shift could contribute to economic resilience and growth in the community.

In conclusion, Pen Argyl remains a predominantly white, low-diversity community, but it is showing signs of gradual change. This evolution, coupled with generally positive economic indicators, points to a community in the early stages of a demographic and economic transition that could reshape its character over the coming years.
