Beginning in the early 1900s, Camden was a prosperous industrial city, and remained so throughout the Great Depression and World War II. During the 1950s, Camden manufacturers began gradually closing their factories and moving out of the city. With the loss of manufacturing jobs came a sharp population decline. The growth of the interstate highway system also played a large role in suburbanization, which resulted in white flight.
