Who lives in Waltham: students, families, and a large Latin American community
About 64,000 residents with a diverse mix: long-established families of Italian and Irish origin, a strong Guatemalan and Ugandan presence, plus the student turnover of two universities.
Waltham's demographic profile reflects two distinct layers. The first is the historic community, with Italian, Irish, and Portuguese roots tracing back to factory workers who arrived in the late 19th and early 20th centuries. Several Catholic parishes and ethnic social clubs still operate in the city, particularly near the South Side.
The second layer is more recent immigration from Central America, especially Guatemala, with a visible presence along Moody Street and the surrounding blocks. Haitian, Brazilian, Indian, and Chinese residents also call Waltham home, the latter two drawn by tech sector openings and the graduate programs at Brandeis and Bentley.
English is the primary language, though Spanish is commonly heard in Moody Street commerce, and several schools offer bilingual programs. Christianity is the predominant religion, divided among Catholics, Protestants, and an active synagogue connected to the strong Jewish tradition at Brandeis.
