Direct economic impacts of job development in new and expanded plants in four developing areas within Arizona, Appalachia, the Mississippi Delta, and the Ozarks were estimated. Approximately 25 percent of all jobs in these plants in 1970 were held by employees whose households had been poor. About 16 percent of the total jobs (two-thirds of the poor) were held by persons whose households escaped poverty by 1970 in their present employment. Discounted value of the increase in employees’ salaries was $12,880. Impacts of jobs varied considerably among areas.
