Over the past decade, Adel has maintained its status as a "Low Diversity" community with a "White Majority." However, subtle signs of a gradual shift towards increased diversity are present, potentially indicating the early stages of a "Transitional Community." The white population decreased from 96% in 2014 to 91% in 2022. The Hispanic population increased from 2% in 2014 to 3% in 2022. The population of two or more races increased from 1% in 2014 to 3% in 2022. Both Asian and Black populations increased slightly from 0% to 1% over the decade. These changes, while modest, suggest a slow but consistent trend towards greater diversity, though not yet sufficient to shift the community out of the "Low Diversity" category.

The demographic shifts in Adel correlate with significant economic growth. The median income increased from $70,102 in 2014 to $93,134 in 2022, a 32.9% increase. The population grew from 8,555 in 2014 to 11,487 in 2022, a 34.3% increase. This substantial growth in both income and population suggests that Adel has been experiencing economic prosperity, which may be attracting a more diverse population. The increasing median income could be a factor in drawing new residents from various backgrounds, contributing to the gradual increase in diversity.
