From 2020 to 2022, the trend moved towards "High Diversity." By 2022, no single group exceeded 40% of the population, with Asians (38%), whites (25%), and those of two or more races (16%) being the largest groups. This indicates a "Transitional Community" as the neighborhood continues to diversify.

The median income has fluctuated over the years but remained consistently high, ranging from $123,274 to $161,486. The highest median income ($161,486 in 2014) coincided with the period when the Asian population became the largest group. The recent trend towards higher diversity has been accompanied by a slight decrease in median income.

The population has grown from 429 in 2010 to 1,473 in 2022. This population growth, combined with the diversification trend, indicates that Quail Ranch Estates has become an increasingly desirable location for various ethnic groups.

The demographic shifts in Quail Ranch Estates reflect broader trends in California and the United States, where many suburban areas are becoming increasingly diverse. The rapid transition from a white majority to a highly diverse community within a decade is noteworthy. The significant growth in the Asian population, especially in the earlier part of the decade, aligns with broader trends of Asian immigration and internal migration to suburban areas in California.

Quail Ranch Estates has transformed from a predominantly white, affluent suburb to a highly diverse, still affluent community. This transition reflects broader demographic shifts but is notable for its rapidity and the maintenance of high median incomes throughout the process. The neighborhood's evolution suggests a dynamic community that has attracted a diverse population while retaining its economic prosperity.
