The upward trend in median income correlates with the subtle demographic shifts observed. The increasing income levels may be attracting a more diverse population to the area, albeit at a slow pace. Conversely, the area's economic prosperity might be contributing to its ability to maintain a relatively homogeneous racial composition, as high housing costs could limit accessibility for some demographic groups.

Population growth has been modest but steady, increasing from 23,365 in 2013 to 25,605 in 2022. This growth aligns with the gradual diversification trend and rising incomes, suggesting that the area is becoming increasingly attractive to new residents while maintaining its overall demographic character.

The trends observed in this zip code align with broader patterns seen in many suburban areas across the United States. Many suburbs are experiencing gradual diversification, often driven by increased mobility of minority populations into traditionally white suburban areas, growing acceptance and instances of interracial relationships and multiracial families, and economic development attracting a more diverse workforce.

The rate of diversification in this zip code appears to be slower than national averages, which have shown more rapid changes in racial composition over the past decade. The area's high median income and predominantly white population suggest it may be a more exclusive suburb, potentially with higher barriers to entry for some demographic groups.

In conclusion, while the 84109 zip code in Millcreek, Utah, remains a "Low Diversity" area, subtle demographic shifts and steady economic growth indicate a community in the early stages of transition. The coming years may reveal whether these trends accelerate, potentially moving the area towards a more diverse demographic profile, or whether economic factors will continue to maintain its current composition.
