The median income for this zip code in 2022 was $83,903.
Throughout the period from 2013 to 2022, the community has maintained its Low Diversity status, with the white population comprising between 75% to 100% of the total. There have been no significant shifts in racial composition, indicating a stable, homogeneous community structure. This consistency suggests a lack of demographic transition or influx of diverse populations over the past decade.
Despite the stable racial demographics, there have been fluctuations in median income. From 2013 to 2021, there was a general upward trend in median income, rising from $57,499 to $84,100, an increase of about 46%.

The income level has remained relatively stable since 2020, with only minor fluctuations.
These economic changes occurred against a backdrop of minimal population change, with the community size ranging from 4 to 6 individuals throughout the decade. This suggests that income growth was likely due to individual economic advancement rather than demographic shifts or new high-income residents moving into the area.
The stability in racial composition is atypical compared to national trends, which generally show increasing diversity in many communities. However, the economic growth observed in this zip code aligns with broader trends of rising incomes in rural and small-town America over the past decade.
The very small population size of this zip code (4-6 individuals) makes it an outlier in demographic studies and limits the applicability of standard diversity measures. In communities this small, individual household changes can have outsized effects on overall statistics.
The consistent Low Diversity categorization and stable White Majority status of this community over the entire period suggest that it has not experienced the Transitional Community phenomenon observed in many other parts of the country. This could be due to its rural location, limited housing stock, or other factors that have kept the community composition stable.
Zip code 51009 has seen significant economic growth over the past decade, while its racial and demographic composition has remained constant. This portrays a small, stable community that has experienced economic advancement without accompanying demographic shifts, setting it apart from many national trends towards increasing diversity and community transition.
