Hispanic majority with strong Salvadoran and Dominican roots
Brentwood has roughly 66,000 residents, with a Hispanic or Latino majority, a significant African American community, and a non-Hispanic white minority that has been declining for two decades.
The population hovers around 66,000 people within a few square kilometers, making Brentwood one of the most populous hamlets in New York State. The majority identifies as Hispanic or Latino, with a strong presence of Salvadoran, Dominican, Honduran, Guatemalan, and Puerto Rican families.
There is also a well-established African American community with active Baptist and Pentecostal churches, along with smaller Asian minorities, primarily Filipino and South Asian, connected to the region's hospitals. The age profile skews young by Long Island standards, with many families in school-age brackets.
Spanish coexists with English in daily life, and the Brentwood Union Free School District runs well-developed bilingual programs. Catholic churches such as St. Anne offer Spanish-language Masses, while evangelical congregations serve worshippers in Creole, Spanish, and English.
