Most of the jobs in 1920 were manual labor followed by work related to clothing and food. The local shipyard provided assembly jobs and the port brought in captains, the U.S. Navy, and boat hands. The groups are detailed out below.
When comparing this data to the 1910 Census, the number of jobs and the types of jobs reported are fairly similar. Two notable changes are the presence of a doctor and the large increase of jobs relating to the naval yard and ships in general. The bicycle repairman and the cigar maker give insight to the neighborhood, too. To warrant a repair shop, bicycles must have been popular and affordable enough for a working-class neighborhood to have a dedicated business. The cigar maker stands out as a surprising occupation and local business when compared to other, more similar, jobs by those living in the Belmont-DeVilliers neighborhood.
