Zip code 20818 in Cabin John, Maryland, demonstrates characteristics of a White Majority community with increasing diversity. As of 2022, the white population comprises 63% of the total, a significant majority that has decreased over the past decade. The area is characterized by high median incomes, with the 2022 figure at $178,372, exceeding national averages.
Over the past decade, Cabin John has transitioned from a Low Diversity community to one categorized as Moderate Diversity. In 2013, the area showed Low Diversity with the white population at 86%. By 2022, this percentage had dropped to 63%, while other racial groups, particularly Asian, Hispanic, and those of two or more races, saw increases.
This shift indicates that Cabin John is becoming a Transitional Community. The decrease in the white population percentage from 86% in 2013 to 63% in 2022, coupled with increases in other racial groups, points to a trend of increasing diversity. The Asian population grew from 4% to 11%, the Hispanic population from 4% to 11%, and those identifying as two or more races increased from 5% to 9% over this period.
The increasing diversity has not led to a decrease in median income. The median income has remained high throughout this period, fluctuating between approximately $170,000 and $200,000. This suggests that the area is attracting diverse, high-income residents. The population has remained relatively stable over the decade, with minor fluctuations, indicating that the demographic changes are likely due to turnover in residents rather than significant population growth or decline.
The rate of change in Cabin John appears to be more rapid than the national average. The persistently high median income, far above the national median, suggests that this area is attractive to high-earning professionals from diverse backgrounds. The transition from Low Diversity to Moderate Diversity in a high-income area like Cabin John could be indicative of broader trends in affluent suburbs near major metropolitan areas.
Cabin John represents a Transitional Community, evolving from Low Diversity to Moderate Diversity while maintaining its status as a high-income area. This trend suggests a complex interplay between economic opportunity, changing social dynamics, and possibly shifting preferences among high-income earners of diverse backgrounds. The community's evolution offers a case study in how affluent areas near major cities are adapting to and reflecting broader demographic shifts in the United States.
