Who Lives in Smithtown
A predominantly white population of Italian, Irish, and German descent, with a growing presence of Asian and Latino families in recent years.
The township has approximately 116,000 residents distributed across its various hamlets. The ethnic composition reflects Long Island's history: many descendants of Italians, Irish, and Germans who relocated from Brooklyn and Queens between the 1950s and 1970s. Established families, multiple generations on the same street.
Over the past two decades, the population has diversified. Asian communities have grown, particularly in Commack and Hauppauge, with Chinese, Indian, and Korean families drawn by the school districts. The Latino population has also increased, with Salvadorans, Ecuadorians, and Mexicans working in retail and construction.
The age profile is balanced, with a strong presence of families with school-age children alongside residents over 55 who have aged in place. Median household income is above the Suffolk County average, giving much of the township a distinctly middle- to upper-middle-class character.
