Throughout the 2013-2022 period, Upper Arlington has consistently maintained its status as a White Majority area. However, there are subtle signs of increasing diversity. The white population has gradually decreased from 88% in 2013 to 82% in 2022, though still firmly in the Low Diversity category. The Asian population has seen the most significant growth, increasing from 5% to 8% over the decade. The Black and Hispanic populations have remained relatively stable, each growing slightly from 1% to 2% and 2% to 3%, respectively. The population identifying as two or more races has increased from 1% to 5%, indicating a trend towards more multiracial families or individuals.

The median income in Upper Arlington has shown an overall upward trend. In 2013, the median income was $102,346. By 2021, it peaked at $124,504, a significant increase of over 21%. There was a slight decrease to $109,209 in 2022, but this still represents a 6.7% increase from 2013. These income trends correlate with the subtle demographic shifts. The increasing Asian population may be linked to high-skilled immigration, often associated with tech or professional sectors. The rising median income could be attracting a more diverse, albeit still predominantly white, affluent population. The slight increase in diversity hasn't significantly altered the area's economic profile, suggesting that new residents are likely of similar socioeconomic status.
