During the late 1920s and early 1930s the town continued to flourish despite the onset of the Great Depression. The 1930 U.S. Census tallied the town population at 845 persons, an increase of 91 people since 1920. The railroad company largely contributed to the growth of not only the population, but the town's economy as well. As a result, expanded town services included necessary public utilities such as electric service when Potomac Edison was established in Mount Airy. The thriving economy supported the initiation of several large businesses in the 1930s, such as a poultry operation, two automobile garages, an ice factory, and the creation of the Mount Airy Canning Company, which provided about 250 jobs. In 1932, the first motion picture theater opened in Mount Airy, establishing a core business district. During that time, the town also saw the purchase of land for a town park, the opening of a grocery store and a lumberyard, and the dedication of Pine Grove Chapel for use as a nonsectarian chapel.
