The median income in McDougal has fluctuated over the years but has generally remained high. It peaked at $185,029 in 2018 before declining to $124,115 in 2022. Despite this recent decline, the median income remains well above national averages, reflecting the area's continued economic prosperity.

The population has remained relatively stable over the decade, with minor fluctuations. This suggests that the demographic shifts are more likely due to changing composition of existing residents or selective in-migration and out-migration rather than large-scale population changes.

The trends observed in McDougal align with broader patterns seen in many affluent, tech-centric areas of California. The increasing diversity, particularly the growth in multiracial populations and the decline in the white majority, mirrors statewide demographic shifts. However, McDougal's consistently high median income sets it apart from many other diversifying communities.

The neighborhood's evolution from a predominantly white community to one of moderate diversity reflects larger national trends towards increased racial and ethnic diversity, especially in urban and suburban areas. However, the retention of high income levels throughout this transition is less common and likely speaks to the unique economic opportunities in the Silicon Valley region.

McDougal presents a case study of increasing diversity within a high-income, tech-influenced community. Its transition from a white majority to a moderately diverse neighborhood with a white plurality, while maintaining high median incomes, showcases an interplay between demographic shifts and economic stability in one of America's most dynamic regions.
