Zip code 91521 in Burbank, California, transitioned from a low diversity area to a moderate diversity community between 2013 and 2022. As of 2022, the area is characterized by significant representation from multiple racial groups: White (39%), Hispanic (35%), and Asian (26%). This demographic composition reflects a notable change from 2013 when the White population constituted 80% of the total.
The community underwent several phases of demographic transition over the decade. From 2013 to 2016, it remained predominantly White but showed increasing diversity. Between 2017 and 2019, it shifted to a "White Plurality" as the White population dropped below 50% but remained the largest group. A brief period of "Hispanic Plurality" occurred in 2020-2021. By 2022, the community reached a "Moderate Diversity" classification with three significant racial groups each representing over 20% of the population.
The demographic shifts correlated with economic changes in the area. From 2013 to 2018, the median income remained relatively stable, ranging from $54,000 to $58,000, coinciding with the period of White majority. A significant increase in median income occurred from 2019 to 2022, rising from over $96,000 in 2019 to exceeding $111,000 by 2022. This economic growth coincided with the transition to greater diversity and the rise in Hispanic and Asian populations.
The population in zip code 91521 fluctuated between 200-400 residents throughout the decade, with no clear trend correlating to demographic or economic changes. The increasing diversity in this zip code aligns with broader trends seen in many urban and suburban areas of California and the United States.
The transition from a predominantly White community to one of moderate diversity within a decade represents a relatively rapid change, potentially reflecting broader shifts in the Los Angeles metropolitan area. The correlation between increased diversity and rising median income is notable, as it contrasts with some national trends where increased diversity has not always been associated with economic growth.
Zip code 91521 has a very small population and land area, which can make it more susceptible to rapid demographic and economic shifts compared to larger, more stable communities. The changes observed here may be part of a localized phenomenon rather than indicative of broader regional trends.
This analysis reveals a community in transition, moving from low diversity to moderate diversity, with concurrent significant economic growth. These changes likely have implications for local culture, community dynamics, and potentially for local businesses and services adapting to serve a more diverse and affluent population.
