This economic growth correlates with the increasing diversity, particularly the growth in the Asian population. The rising Hispanic population, coupled with increasing median incomes, might suggest an influx of more affluent Hispanic residents or upward economic mobility within this group.

Population figures have remained relatively stable, fluctuating between about 5,900 and 6,300 residents over the decade. This stability, combined with rising incomes and increasing diversity, may indicate a gradual replacement of some existing residents with new, diverse, high-income households rather than significant new development or population growth.

The trends observed in Allentown align with broader patterns seen in many suburban communities across the United States. These include gradual diversification of traditionally white-majority areas, increasing representation of Asian and Hispanic populations in high-income suburbs, and rising median incomes in desirable suburban locations.

The pace of change in Allentown appears slower than in many rapidly diversifying suburbs, particularly those near major metropolitan areas. The community's continued low diversity and high median income suggest it remains a relatively exclusive enclave, possibly due to high housing costs or limited new development.

Allentown remains a low-diversity, high-income area. Subtle demographic shifts over the past decade hint at a slow transition towards greater diversity. This gradual change, occurring alongside rising incomes, reflects broader national trends of suburban diversification but at a more measured pace. As this evolution continues, it may eventually lead to a more diverse community composition, potentially bringing new perspectives, businesses, and cultural influences to the area while maintaining its economic prosperity.
