East Moriches's slow diversification trend aligns with broader national patterns of increasing diversity in suburban areas. However, the pace of change is slower than in many other suburban communities across the United States.

The area's median income is higher than the national median household income, which was about $70,784 in 2021. This indicates that East Moriches is an affluent community, even within the context of New York State, which generally has higher incomes than the national average.

The gradual increase in diversity, coupled with rising incomes, suggests that the area may be attracting affluent minorities, potentially professionals or families seeking suburban lifestyles. The relatively slow pace of diversification could indicate barriers to entry for minority groups, such as high housing costs or limited affordable housing options.

East Moriches remains a "White Majority" area with "Low Diversity," but there are signs of gradual change. The community is experiencing steady economic growth and subtle demographic shifts, potentially setting the stage for more significant changes in the coming decades if current trends continue.
