Castle Rock, Washington (zip code 98611) exhibits demographic stability with minor economic fluctuations from 2013 to 2022. The community is categorized as "Low Diversity" with a White Majority comprising 89% of the population in 2022.

Throughout the 2013-2022 period, Castle Rock has maintained its Low Diversity status with a strong White Majority. The white population has remained above 87% during this time, showing only slight fluctuations. A minor decrease from 92% in 2013 to 89% in 2022 suggests a gradual trend towards increased diversity, though still within the Low Diversity category.
The Hispanic population increased slightly from 3% in 2013 to 5% in 2020, before returning to 3% in 2022. The "Two or More Races" category experienced a small increase from 3% in 2013 to 4% in 2022, peaking at 5% in some years. These gradual changes may indicate a slow trend towards increased diversity in future generations.
The median income in Castle Rock has fluctuated over the decade. It started at $66,830 in 2013, reached a peak of $75,445 in 2021, and then decreased to $67,171 in 2022. This trend suggests economic stability with some growth, particularly in the latter part of the decade. Periods of slightly higher diversity coincided with higher median incomes, as seen in 2020 and 2021.
The population has remained relatively stable, ranging between approximately 9,200 and 10,000 residents throughout the decade. This population stability, combined with the consistent racial composition, suggests minimal in-migration or out-migration in the community.
Compared to national trends of increasing diversity, Castle Rock is changing at a slower rate. The persistent White Majority and Low Diversity categorization contrast with many urban and suburban areas that have experienced more rapid demographic shifts during the same period.
The median income in Castle Rock has generally kept pace with or slightly exceeded the national median household income, indicating a relatively prosperous community. However, the lack of significant demographic change may suggest limited economic diversification or new industry growth that could attract a more diverse population.
Castle Rock demonstrates demographic stability with slight economic growth. While there are minor indications of increasing diversity, the community remains firmly in the Low Diversity, White Majority category. The economic fluctuations, particularly the rise in median income towards the end of the decade, may set the stage for future demographic changes, but as of 2022, the community's racial composition remains largely unchanged from a decade ago.
