Despite the overall upward trend in median income, there have been fluctuations. There was a significant jump to $70,318 in 2021, followed by a decrease to $67,065 in 2022. The population has grown steadily from 40,596 in 2013 to 43,402 in 2022, an increase of about 6.9%. This growth aligns with the gradual increase in diversity and might be partially attributed to the influx of minority populations.

The gradual diversification trend in this zip code aligns with broader national trends of increasing diversity in many American communities. The income growth, while positive, appears modest compared to national averages, which might suggest that this area has been relatively stable economically but not experiencing rapid economic expansion. The persistent "White Majority" status, despite slow diversification, indicates that this community may be changing more slowly than some other parts of the country that have seen more rapid demographic shifts.

While the zip code 47909 in Shadeland, Indiana, remains a "Low Diversity" area with a strong "White Majority," there are signs of gradual change. The community is showing early indications of transitioning towards greater diversity, coupled with modest economic growth. These trends suggest a slowly evolving demographic and economic landscape that may continue to shift in the coming years, potentially leading to a more diverse community structure in the future.
