Adelaide, a neighborhood in Sammamish, Washington, exhibits a notable demographic profile as of 2022. It is classified as a "Majority-Minority" community, with White residents constituting 49% of the population. This represents a significant change from its recent past. The neighborhood has a median income of $160,560 in 2022, indicating an affluent populace. Adelaide is situated near Lake Sammamish, offering a combination of natural surroundings and suburban living.
Over the past decade, Adelaide has experienced a substantial transformation in its racial composition. In 2013, it was categorized as having "Low Diversity," with a White majority of 70%. By 2022, the neighborhood had progressed to a "Majority-Minority" status. This change is primarily attributed to an increase in the Asian population, which grew from 27% in 2013 to 36% in 2022, and a rise in multiracial residents from 0% to 9% during the same period.
Adelaide can be classified as a "Transitional Community," with consistent increases in racial diversity year-over-year. The percentage of residents identifying as two or more races has shown a notable upward trend, increasing from 0% in 2013 to 11% in 2021, before declining slightly to 9% in 2022. This trend indicates a growing prevalence of multiracial families in the area.
Adelaide's economic profile has remained consistently affluent throughout the observed period. The median income has fluctuated but maintained a high level, reaching $191,770 in 2021 before settling at $160,560 in 2022. The increasing diversity has not led to a decrease in median income, suggesting that new residents are likely high-earning professionals. The population has grown moderately from 3,287 in 2013 to 3,483 in 2022, indicating steady demand for housing in the area.
The demographic shifts observed in Adelaide are similar to trends seen in many affluent suburbs near major tech hubs across the United States. The significant increase in Asian population is reminiscent of changes seen in areas like Silicon Valley. Adelaide's transition is notable for its rapidity and the maintenance of high income levels throughout the process. The stability of Adelaide's economic profile suggests a carefully managed growth process.
The increase in multiracial residents aligns with national trends, as reported by the U.S. Census Bureau in the 2020 census. However, the extent of this increase in Adelaide (from 0% to 9% in less than a decade) is particularly significant. Adelaide presents a case study of rapid demographic diversification in a high-income suburban setting. Its evolution from a predominantly White community to a Majority-Minority area, while maintaining its economic status, provides insights into the changing demographics of affluent American suburbs in the 21st century.
