The economic trajectory of the 90039 zip code has been generally positive over the past decade. The median income increased from $79,566 in 2013 to $95,532 in 2022, representing a 20% increase over nine years. This upward trend in income correlates with the slight increase in white and Asian populations. The population of the zip code has remained relatively stable, fluctuating between 26,000 and 29,000 residents throughout the decade.

The demographic shifts in the 90039 zip code align with broader trends seen in many urban areas across the United States. The slight increase in white and Asian populations, coupled with a decrease in the Hispanic population, resembles gentrification patterns observed in other major cities. The rising median income in this zip code outpaces the national average income growth, indicating increasing affluence in this area of Los Angeles.

The maintenance of racial diversity in this zip code, despite economic changes, is noteworthy. Many urban areas experiencing similar income increases have seen more dramatic shifts towards lower diversity. The 90039 area appears to balance economic growth with maintaining a diverse community, which could be attributed to Los Angeles's overall diverse character and policies aimed at preserving mixed-income neighborhoods.

In conclusion, the 90039 zip code demonstrates moderate demographic change coupled with significant economic growth. While the area has become slightly less diverse over the decade, it has maintained its status as a "Moderate Diversity" community, avoiding more extreme shifts seen in some rapidly gentrifying urban areas. This balance between economic growth and demographic stability could serve as a model for other urban areas facing similar challenges of development and diversity.
