The median income has shown a strong upward trend, increasing from $121,616 in 2013 to $146,474 in 2022, representing a growth of about 20% over the decade. The population has remained relatively stable, fluctuating between about 21,700 and 22,600 throughout the period, with no dramatic changes. The rising median income correlates with the increasing diversity, suggesting that the area is attracting affluent members of minority groups.

The trends observed in Seaford align with broader patterns seen in many affluent suburbs across the United States. These include gradual diversification of traditionally white suburban areas, increasing median incomes in desirable suburban locations, and slow but steady integration of minority groups into previously homogeneous communities. These changes reflect wider societal shifts, including increased economic mobility among minority groups and changing preferences for suburban living across diverse populations.

The stability in population numbers suggests that this area remains desirable and may have limited housing availability, which could be contributing to the gradual nature of demographic changes. While Seaford remains a predominantly white, affluent suburb, it shows signs of gradual diversification. This trend, coupled with rising median incomes, suggests a slow but steady evolution towards a more diverse, yet still economically prosperous community. The coming years may see this area potentially shift from "Low Diversity" to "Moderate Diversity" if current trends continue.
