The 98077 zip code area of Cottage Lake, Washington, is classified as a "White Majority" community with low diversity as of 2022. The area has a population of 14,148 and a median household income of $163,186, which is significantly higher than the national average. This affluent suburb has maintained a predominantly white population over the past decade, though there have been subtle shifts towards increased diversity.
Throughout the 2013-2022 period, Cottage Lake has consistently maintained its status as a "White Majority" community. However, there is evidence of a gradual transition towards slightly increased diversity. The white population decreased from 90% in 2013 to 81% in 2022, still solidly in the "White Majority" category but showing a slow diversification trend. The Asian population increased from 4% to 7% over the same period. The Hispanic population doubled from 3% to 6%. The population identifying as two or more races increased from 2% to 5%.
The demographic shifts correlate with significant economic growth. Median household income increased from $142,700 in 2013 to $163,186 in 2022, a 14.4% increase. There was a notable jump in median income from $154,387 in 2019 to $168,282 in 2020, coinciding with a slight increase in diversity. The population has remained relatively stable, fluctuating between about 13,000 and 14,300 residents over the decade.
The rising incomes and gradual increase in diversity suggest that the area is attracting affluent, diverse professionals, possibly due to its proximity to tech hubs or other high-paying job centers.
The income levels in Cottage Lake are significantly higher than the national median household income, which was around $70,784 in 2021. The area's racial composition is less diverse than Washington state as a whole, which had a white population of about 67.5% in 2021. The gradual increase in diversity, particularly in Asian and Hispanic populations, aligns with broader trends seen in many suburban areas near major cities, especially those with strong tech sectors.
While Cottage Lake remains a predominantly white, affluent suburb, it shows signs of a slow transition towards greater diversity. This trend, coupled with rising incomes, suggests the area is evolving in response to broader economic and demographic shifts, potentially influenced by nearby urban centers and changing workforce demographics in high-paying industries. However, the pace of change is gradual, and it may take many more years before the community could be classified differently in terms of diversity.
