The demographic shifts in Smithtown have occurred alongside a general increase in median income. The median income has risen from $121,576 in 2013 to $134,071 in 2022, representing a 10.3% increase over the decade.

This minor population decline (-4%) has occurred simultaneously with the gradual increase in diversity.

The demographic changes in Smithtown reflect broader national trends of increasing diversity in suburban areas, particularly in terms of growth in Hispanic and Asian populations. However, the pace of change in this zip code appears to be slower than in many other suburban areas across the United States.

The high median income and predominantly white population are characteristic of many affluent suburban communities in the New York metropolitan area. The gradual increase in diversity, while maintaining high income levels, suggests that the area is attracting diverse, high-income professionals and families.

Smithtown remains a "White Majority" area with "Low Diversity," but shows signs of slowly transitioning towards greater diversity. This change is occurring in the context of continued economic prosperity, as evidenced by the rising median income. If current trends persist, the community may eventually evolve into a more diverse suburb while maintaining its affluent status.
