Early in its history the town was one of the most industrialized communities in the region, with the concentration of several agri-businesses. Local industrialization has waned with global economic changes over the past several decades, but the town remains linked to agri-industry.
The town recognized a modest diversification in industry at Berwick’s industrial park. Evidence shows that Berwick’s residents support industrial growth. Citizens favor the development of industries which have little or no impact on the environment. They place emphasis on new downtown development and revitalization of older commercial sections.
