Highland Ranch in Gilbert, Arizona, has undergone a demographic transition from Low Diversity to Moderate Diversity between 2013 and 2022. The white population decreased from 76% to 62%, while other racial groups increased their representation. The Black population grew from 3% to 12%, and the Hispanic population increased from 4% to 16%. The Asian population reached 3% by 2022.

The demographic shifts in Highland Ranch correlate with changes in median income. As the community became more diverse, the median income increased from $33,492 in 2013 to $74,571 in 2022. This economic growth might have attracted a more diverse population or resulted from the influx of diverse, skilled professionals. The population fluctuated over the years but generally trended upward, from 1,834 in 2013 to 1,621 in 2022, with a peak of 2,642 in 2019.

The trends observed in Highland Ranch align with broader national patterns of increasing diversity in suburban areas. Many suburbs across the United States have seen similar transitions from predominantly white communities to more diverse neighborhoods over the past decade. The substantial increase in median income also reflects a national trend of growing economic disparities, with some suburban areas experiencing rapid gentrification and economic growth.
