The onset of the Great Depression in the 1930s forced many businesses to close, and in 1936 Atlanta had 85 rated businesses. The opening of the Rodessa oilfield in 1935, however, helped mitigate the worst effects of the Depression. By 1940 the town had modern canneries, lumber mills, wholesale houses, a brick plant, a hospital, and a population of 2,453. Subsequently, Atlanta grew steadily, topping the 4,000 mark for the first time in the early 1960s. In 1990 the population was 6,118. By 2000 the population had dropped to 5,745. Principal industries include farming, forestry, oil, and tourism.
