For nearly 30 years the Newman Lumber Company was the main industry of the city. As the timber industry was a "cut out and get out" operation at this time, when the mill depleted the profitable timber supply it ceased operation in 1931. Combined with the Great Depression, the shutdown of the mill had a marked impact on the town and left it with no large employer for nearly 20 years. In 1949, the Movie Star Company opened a plant in nearby Purvis, and soon opened a similar plant in Sumrall which provided stable employment for many local women until the 1990s. The population of the city remained flat or declined from 1940-2000. As the metropolitan area of Hattiesburg has expanded westward, Sumrall is now once again experiencing economic growth. The Longleaf Trace, a recreational trail which follows the route of the former Mississippi Central Railroad, runs through the center of town. The Longleaf Trace extends from Hattiesburg, MS to Prentiss Mississippi and is popular with bikers, hikers, and horseback riders.
