Port Costa, located in California with zip code 94569, exhibits characteristics of a Low Diversity community. As of 2022, the white population constitutes 80% of the total, establishing it as a White Majority area. The zip code covers an area of 0.74 square miles, with a population of 265 in 2022, indicating a relatively sparse population density.
Over the past decade, Port Costa has maintained its status as a White Majority community, but with notable fluctuations. From 2013 to 2018, the area showed signs of transitioning towards Moderate Diversity. The white population decreased from 83% to 69%, while Hispanic, Asian, and multiracial populations increased. However, from 2019 onwards, there was a reversal of this trend, with the white population increasing again to 80% by 2022, reinforcing its Low Diversity classification.
The Hispanic population, which peaked at 17% in 2017, has since declined to 8% in 2022, indicating a possible outmigration of this group. There has been a small but consistent increase in the Asian population, from 1% in 2013 to 6% in 2022, suggesting a gradual influx of this demographic.
The median income in Port Costa has shown significant volatility over the past decade. From 2013 to 2018, there was a general upward trend in median income, peaking at $123,429 in 2018. This coincided with the period of increasing diversity. However, from 2019 to 2022, there was a dramatic decline in median income, dropping to $85,921 in 2022. This economic downturn aligns with the reversal of the diversity trend and the reinforcement of the White Majority status.
The population has remained relatively stable throughout this period, fluctuating between 239 and 293 residents, suggesting that changes in diversity and income are more likely due to demographic turnover rather than significant population growth or decline.
The trend of increasing diversity followed by a reversal is unusual compared to national trends, which generally show a continuous increase in diversity across most communities. The sharp decline in median income from 2018 to 2022 is more severe than typical national trends, suggesting local economic factors may be at play. The maintenance of a White Majority status in a California community is less common, especially in more urban areas, indicating that Port Costa may be a more isolated or rural locality.
Port Costa has experienced a complex demographic evolution over the past decade. While it briefly trended towards greater diversity, recent years have seen a reinforcement of its White Majority status, coinciding with a significant economic downturn. These trends suggest a community in flux, potentially grappling with economic challenges that are influencing its demographic composition. The small size and population of the area may make it particularly susceptible to rapid changes based on the movement of even a small number of residents.
