The zip code 91108 in San Marino, California, transitioned from a "Moderate Diversity" community to an "Asian Majority" between 2013 and 2022. This demographic shift occurred alongside economic fluctuations in the area.
In 2013, the community exhibited "Moderate Diversity" with a 50% Asian population and a 40% White population. By 2022, the Asian population had increased to 67%, while the White population decreased to 23%. This change indicates a gradual but consistent transition towards an Asian majority over the decade.
The median income in San Marino fluctuated during this period but remained consistently high. In 2013, the median income was $165,837, and by 2022 it had slightly decreased to $157,318. The peak median income of $172,890 was recorded in 2018, coinciding with a rapid increase in the Asian population percentage.
The population of zip code 91108 declined from 13,504 in 2013 to 12,693 in 2022. This decrease, coupled with the maintained high median income, may indicate a trend towards larger, more affluent households replacing smaller or less affluent ones.
The demographic shift observed in San Marino reflects broader trends seen in many affluent suburbs of major Californian cities. This trend is often associated with highly skilled immigration and generational wealth accumulation within Asian-American communities.
The consistently high median income in San Marino places it well above both the California and national median household incomes. This suggests that San Marino remains an exceptionally affluent enclave, even as its racial composition shifts.
The declining population coupled with sustained high incomes could indicate a trend towards exclusivity, potentially driven by rising property values and a preference for larger, luxury homes. This pattern is observed in other high-income areas across the United States.
San Marino presents a case of a "Transitional Community" evolving into an "Asian Majority" area while maintaining its status as a high-income locality. These changes reflect broader regional demographic shifts and economic trends, demonstrating the dynamic nature of suburban demographics in California and the United States.
