The median income in this zip code has increased over the past decade, rising from $81,898 in 2013 to $96,337 in 2022, an increase of about 17.6%. This growth in median income correlates with the increasing diversity of the area, particularly the growth in the Asian and mixed-race populations. The population has grown slightly, from 17,501 in 2013 to 18,769 in 2022, an increase of about 7.2%. This modest population growth, combined with the significant income increase, suggests that the area has become more attractive to higher-income residents of various racial backgrounds.

The trends observed in this zip code align with broader national patterns of increasing diversity in suburban areas, particularly those with strong economic indicators. The significant increase in the mixed-race population is consistent with national trends, as the multiracial population in the United States has been one of the fastest-growing demographic groups in recent years. The economic growth in this area outpaces the national average, with the median household income in the United States growing by about 10% over a similar period.

The maintenance of a white majority, while simultaneously increasing in diversity, is characteristic of many affluent suburbs across the United States. These areas often attract diverse, high-income professionals while retaining long-term residents, leading to a gradual demographic shift. Zip code 48334 in Farmington Hills represents a "White Majority" community that is gradually transitioning towards greater diversity. Its economic strength, as evidenced by significant income growth, appears to be both a driver and a result of these demographic changes. The area seems poised for continued evolution towards increased diversity in the coming years, potentially moving towards a "Moderate Diversity" or "High Diversity" classification if current trends continue.
