The median income in Zionsville has shown a generally upward trend, with some fluctuations. From $58,875 in 2013 to $80,618 in 2022, there was a substantial increase of about 37% over nine years. The population grew from 6,980 in 2013 to 9,072 in 2022, an increase of about 30%. The increase in median income has coincided with the gradual increase in diversity, suggesting that the area may be attracting more affluent and diverse residents.

The high median income and predominantly white population are characteristic of many affluent suburban areas in the United States. The slow but steady increase in diversity mirrors broader national trends of suburban areas becoming more diverse, particularly with growth in Hispanic and multi-racial populations. The consistent growth in both population and median income suggests that Zionsville has been economically resilient.

In conclusion, while Zionsville remains a "Low Diversity" community with a strong "White Majority," it shows signs of transitioning towards greater diversity. This demographic shift, coupled with robust economic growth, suggests a community in the early stages of change. The coming years may see further diversification if current trends continue, potentially moving the area towards "Moderate Diversity" in the future. The economic prosperity of the area appears to be a driving factor in attracting a more diverse population, albeit at a gradual pace.
