These individuals are distributed across 10,950 households, reflecting a mix of family and individual living arrangements. With 11,244 total housing units in the area, there’s a slight surplus of homes compared to occupied households, which could indicate some availability for new residents or investors looking to enter the market. The average household size here suggests a balance of families and smaller units, catering to a range of lifestyle needs.
The median household income in ZIP 90621 stands at $94,679, which is a strong figure compared to national averages. This suggests a relatively affluent community with disposable income to support local businesses and sustain a comfortable standard of living. However, housing costs reflect the premium nature of the area. The median house value is $734,400, indicating a high barrier to entry for homebuyers but also significant potential for property value appreciation for investors. For renters, the median rent is $2,061 per month, which aligns with the area’s higher cost of living and may influence decisions for those seeking affordable housing options.
ZIP 90621 boasts a richly diverse population, which shapes the cultural fabric of the community.

This diversity offers a unique blend of perspectives, traditions, and opportunities for businesses catering to varied cultural needs. It also signals an inclusive environment for families and individuals from different backgrounds looking to settle in the area.
For homebuyers, ZIP 90621 offers a diverse and vibrant community with a strong median income, but the high median house value of $734,400 means you’ll need to budget carefully or explore financing options. The slight surplus of housing units could provide some negotiation leverage if inventory remains available. Investors and agents will find potential in the area’s high property values and income levels, which suggest long-term appreciation and a stable tenant base for rentals, though the $2,061 median rent may limit the pool of renters to higher-income brackets. Small-business owners can capitalize on the diverse population and solid household incomes to offer culturally relevant products or services, especially those appealing to Hispanic and Asian communities. Analysts can use this data to track trends in housing affordability and demographic shifts, particularly given the area’s unique ethnic composition.
