The zip code 15101 in Allison Park, Pennsylvania, is classified as a "Low Diversity" area with a "White Majority" as of 2022. The racial composition consists of 91% white population, with minor representations of other racial groups. The median income of $93,145 in 2022 indicates an affluent community, exceeding the national median income.
Over the past decade, Allison Park has maintained its status as a "Low Diversity" area with a strong "White Majority." The white population has remained above 90% throughout this period, with minimal fluctuations. There are subtle indications of increasing diversity: the Asian population has remained at approximately 3-4% since 2013, the Black population increased slightly from 1% in 2013 to 2-3% in recent years, the Hispanic population has shown small but consistent growth, reaching 2% by 2022, and the "Two or More Races" category emerged and grew to 2% by 2022. These changes suggest a slow trend towards slightly increased diversity, though not sufficient to alter the area's "Low Diversity" classification.
The median income in Allison Park has fluctuated over the past decade but generally remained high. It peaked at $98,508 in 2014 before declining to $92,358 in 2020. A significant increase to $104,054 occurred in 2021, followed by a return to $93,145 in 2022. These income levels consistently place the area above national averages, indicating a wealthy community. The slight increase in diversity has not significantly impacted the overall economic status of the area.
Population trends show relative stability, with minor fluctuations between 24,755 (2014) and 26,350 (2021). The recent uptick in population coincides with the income spike in 2021, possibly indicating an influx of high-earning residents.
Allison Park's demographic and economic trends differ from many national patterns. While many urban and suburban areas across the U.S. have experienced significant increases in diversity over the past decade, Allison Park has maintained a highly homogeneous racial composition. The area's consistently high median income and predominantly white population suggest it may be less affected by broader national trends of increasing income inequality and racial economic disparities. The stability in both racial composition and high income levels could indicate that Allison Park is a relatively insulated community, possibly with limited housing turnover or new development that might otherwise drive demographic changes. The slight increases in minority populations, while small, align with national trends of slowly increasing diversity in suburban areas, albeit at a much slower pace in this zip code.
In conclusion, while Allison Park shows some minimal signs of increasing diversity, it remains a predominantly white, affluent area with high economic stability. The community has not experienced the rapid demographic shifts seen in many other parts of the country, maintaining its character as a "Low Diversity" area with a strong "White Majority" over the past decade.
