There was an increase from $67,584 in 2020 to $73,183 in 2021, followed by a decrease to $67,458 in 2022. These changes coincide with the demographic shifts, suggesting a possible correlation between increasing diversity and economic fluctuations.

The population of the zip code has remained relatively stable over the decade, with a slight decrease from 23,530 in 2013 to 23,759 in 2022. This stability, combined with the increasing diversity, may indicate that the area is attracting new residents from diverse backgrounds while maintaining its overall population size.

The demographic changes in Highland reflect broader national trends of increasing diversity in suburban areas. Many similar communities across the United States have experienced a gradual shift from predominantly white populations to more diverse compositions, particularly with growth in Hispanic and Black populations.

The economic fluctuations, especially the rise and fall in median income between 2020 and 2022, may be related to the broader economic impacts of the COVID-19 pandemic and subsequent recovery efforts. This pattern is consistent with many middle-class suburban areas across the country during this period.

Highland (zip code 46322) is experiencing a gradual but significant demographic transition, moving from a low-diversity, predominantly white community to one with moderate diversity and a growing minority population. These changes, coupled with economic fluctuations, suggest that the area is adapting to broader societal shifts while maintaining its middle-class suburban character.
