A 2012 study by the Missouri Department of Transportation revealed that 108 of the airports it helps support contribute 100,621 jobs with a payroll of $ 3.1 billion to the Missouri economy. When all economic activities are considered, total annual economic output of Missouri’s system of airports is estimated at $11.1 billion. This represents 4.3 percent of the gross state product.
Aviation and airports' value goes beyond economic contributions. Aviation also contributes to Missourians' quality of life, through rescue and health flights, agricultural spraying, forest and traffic monitoring and other activities.
