The median income in Oceanside has fluctuated but generally maintained a high level. It rose from $114,013 in 2013 to $137,570 in 2021, before settling at $118,291 in 2022. This upward trend in income correlates with the increasing diversity, suggesting the area remains attractive to middle and upper-middle-class families from various ethnic backgrounds.

The population has grown slightly from 28,654 in 2013 to 30,174 in 2022. This modest growth, combined with increasing diversity and high median income, suggests a gradual integration of different ethnic groups into an established, affluent community.

The trends in Oceanside align with broader patterns seen in many suburban areas near major metropolitan centers. The gradual increase in diversity, particularly in Hispanic and Asian populations, reflects national demographic shifts. However, the area's continued "White Majority" status and high median income suggest it may be changing more slowly than some other suburban areas.

The stability of the high median income, even as diversity increases, is notable. It suggests that the area is attracting affluent members of minority groups, possibly professionals or second-generation immigrants who have achieved economic success.

While Oceanside remains a "White Majority" area with "Low Diversity," it shows signs of being a "Transitional Community." The gradual increase in diversity, coupled with maintained high median incomes, suggests a slow but steady evolution towards a more multicultural community while retaining its affluent character. This trajectory aligns with broader national trends of increasing suburban diversity, particularly in areas near major cities, but the pace of change appears to be more measured in this specific zip code.
