Agri-Industry Modeling & Analysis Group

AIM-AG was established in 1998 as part of the Department of Agricultural and Resource Economics, Agricultural Experiment Station (now AgResearch). The mission of AIM-AG is to assess and project the impacts of agri-industry development on the Tennessee economy and to analyze market opportunities for economically efficient agri-industry development within the state.


  • Evaluates the impacts the agricultural and forest products industry has on the state’s economy and the economics of regions within the state using TN-AIM (Tennessee Agri-Industry Model), an economic modeling system;
  • Conducts “what-if” scenarios designed to evaluate the impacts that occur from development of selected value-added industries in the state and regions within the state;
  • Conducts research studies on market growth opportunities for value-added or high-value agri-industry products;
  • Analyzes market potential and feasibility for value-added or high-value products produced or processed within the state and;
  • Provides market information and prospectus studies to aid industrial recruitment and development.

Tennessee agriculture includes farming and related industries, as well as value-added food and fiber production, processing and manufacturing. Agriculture accounts for 8.3 percent of the state’s economy and generates $56.8 billion in output. Agriculture employs close to 244,000 Tennesseans, with over 92,000 (both full- and part-time) in agriculture production. In 2017, Tennessee had approximately 70,000 farms covering 10.9 million acres. Approximately 62.6 percent of the farms had sales in the $1,000 to $9,999 sales category, 31.0 percent of the farms had sales in the $10,000 to $99,999 sales category, and 6.4 percent of the farms had sales of $100,000 and over (USDA/ERS, 2019). Average farm size in the state was 156 acres compared to 441 acres for the United States. Other southeastern states with similar average farm sizes as Tennessee include South Carolina at 190 acres, followed by North Carolina at 181 acres and Kentucky at 171 acres. Arkansas, Mississippi, and Missouri have the largest average farm sizes at 326, 297, and 292 acres, respectively. Listed below is an overview of Tennessee’s top agricultural commodities.
