The median income in San Gabriel has grown significantly, rising from $67,044 in 2013 to $78,834 in 2022, an increase of approximately 17.6% over nine years. This economic improvement correlates with the stable Asian majority and slight increase in diversity.

The demographic composition of San Gabriel differs notably from the overall U.S. population, where White and Hispanic populations typically form larger percentages. The high Asian population percentage is more characteristic of certain areas in California and other parts of the West Coast.

Based on observed trends, San Gabriel is likely to maintain its status as a "Majority-Minority" community with an Asian majority in the near future. However, the gradual increases in Hispanic population and those identifying as two or more races suggest a slow trend towards greater diversity.

If current trends continue, San Gabriel may transition towards a "Moderate Diversity" categorization in the long term, particularly if the Hispanic population continues to grow and the Asian population slightly declines. This could result in a situation where two groups (Asian and Hispanic) each exceed 20% of the population, meeting the criteria for "Moderate Diversity."

Economically, if the upward trend in median income persists, San Gabriel may experience further prosperity. This could potentially attract more diverse populations, accelerating the shift towards greater diversity.

In conclusion, while San Gabriel currently remains a stable "Majority-Minority" community with "Low Diversity," subtle demographic shifts and strong economic growth indicate a potential for increased diversity and continued prosperity in the coming years.
