The median income in this zip code has demonstrated a significant upward trend over the past decade. In 2013, the median income was $35,536, which has more than doubled to $74,138 in 2022. This increase suggests improving economic conditions for residents.

The population has remained relatively stable during this period, fluctuating between approximately 1,000 and 1,200 residents. The stability in population combined with rising incomes may indicate that the area is becoming more affluent without significant demographic changes or population growth.

The correlation between stable racial composition and rising median income suggests that the existing community has experienced economic growth without attracting a more diverse population. This could be due to factors such as limited housing development, the area's rural nature, or its appeal as a resort community.

The trend in this zip code contrasts with many urban and suburban areas across the United States, which have generally experienced increasing racial diversity over the past decade. The significant increase in median income also outpaces national averages, suggesting that this community may be benefiting from specific local economic factors.

The lack of racial diversity in this zip code, despite economic growth, raises questions about accessibility, housing policies, or cultural factors that might be influencing residency patterns. The area's character as a resort community may contribute to its demographic stability and economic growth without corresponding increases in diversity.

In conclusion, zip code 15622 has experienced substantial economic improvement over the past decade while remaining a "Low Diversity" area with a stable, predominantly white population. This pattern of economic growth without demographic change presents a case study in how some rural or resort communities may evolve differently from more urban areas in terms of diversity and economic development.
