Merrimack demographics: predominantly white suburb with growing diversity
The majority population traces English, Irish, and French-Canadian roots. Indian, Asian, and Latin American communities are growing, tied to skilled employment in the region.
The historical heritage reflects colonial English immigration, with English, Irish, and Scottish surnames dominating. French Canadians arrived in the 19th and 20th centuries, drawn by the region's mills and factories. Italian and Greek communities are modest in size, while the overall majority remains white.
Diversity has increased over the past two decades. South Asians form a visible community, linked to Fidelity, PC Connection, and tech firms along the I-93/I-95 corridor. Chinese and Korean families have established roots. Latin American families, including Mexican, Puerto Rican, and Dominican households, have grown modestly.
Religiously, Roman Catholics, Protestants (Congregationalist, Baptist, Methodist), and Orthodox Christians form the base. Hindu temples in Manchester and Nashua serve South Asian families. Small evangelical congregations serve newer immigrant communities. The Reeds Ferry Meetinghouse is a notable historical landmark.
