Zip code 94531 in Antioch, California, is classified as a "High Diversity" area as of 2022. No single racial group exceeds 40% of the population, with at least three groups having significant representation (over 10% each). The community consists of Hispanic (25%), Black (24%), White (23%), and Asian (20%) populations, with 7% identifying as two or more races. The median household income is $107,933, indicating a relatively affluent suburban community.
Over the past decade, this zip code has transitioned from "Moderate Diversity" to "High Diversity." In 2013, the area was classified as having "Moderate Diversity," with Hispanic (29%), White (27%), and Black (22%) populations being the dominant groups, and the Asian population at 15%. Notable shifts include a decline in the White population from 27% to 23%, an increase in the Asian population from 15% to 20%, a slight decrease in the Hispanic population from 29% to 25%, and relative stability in the Black population around 22-24%. These changes reflect a trend towards increased diversity, with a more balanced representation across multiple racial groups.
The demographic shifts have been accompanied by economic changes. The median household income increased from $99,783 in 2013 to $107,933 in 2022, representing an 8.2% growth. There was a notable spike in median income in 2021 to $124,692, followed by a decrease in 2022. The population grew modestly from 41,496 in 2013 to 42,982 in 2022, a 3.6% increase. The increasing Asian population correlates with the rise in median income, suggesting possible in-migration of higher-income Asian households.
The demographic shifts in this zip code align with broader trends seen in many California suburbs, particularly those in the San Francisco Bay Area. The increasing diversity and rising incomes reflect the region's strong economy and its attraction for diverse, skilled professionals. The transition to "High Diversity" status represents a more balanced representation across racial groups than is typical in many U.S. communities.
The economic growth has been more modest compared to some other Bay Area communities, which have seen more dramatic increases in property values and incomes. This could suggest that the area remains relatively affordable within the context of the broader Bay Area, potentially attracting a mix of middle and upper-middle-class families from various backgrounds.
Zip code 94531 in Antioch has evolved into a highly diverse, economically stable community over the past decade. Its demographic composition reflects broader trends of increasing diversity in California suburbs, while its economic indicators suggest a growing, affluent population. These changes likely have implications for local schools, businesses, and community services, which may need to adapt to serve an increasingly diverse population with changing needs and expectations.
