Arona's demographic stability contrasts with national trends towards increasing diversity in many areas of the United States. The borough's economic trajectory, showing overall growth with some fluctuations, aligns with broader economic patterns seen in many small American communities over the past decade.

Based on the observed trends, Arona is likely to remain a Low Diversity community in the near future. The slight increases in diversity, while notable, are not substantial enough to suggest a rapid transition to a different category. If the small increases in diversity continue or accelerate, the borough might slowly move towards becoming a Transitional Community over the next decade or two.

Economically, the overall upward trend in median income, despite recent fluctuations, suggests continued economic growth. This economic stability, coupled with the borough's resistance to significant demographic changes, indicates that Arona is likely to maintain its current characteristics as a predominantly White, economically stable small town.

Arona presents a case of demographic stability in an era of increasing diversity elsewhere, coupled with overall economic growth. While minor shifts towards increased diversity are observable, they are not yet significant enough to alter the fundamental character of this Low Diversity community. The coming years will reveal whether these small changes are the beginning of a larger trend or merely minor fluctuations in an otherwise stable demographic landscape.
