According to USDA's Economic Research Service (ERS), the national net farm income, a key indicator of U.S. farm well-being, is forecast at a record $121 billion in 2013, up 6% from last year, and about $3 billion above 2011's previous record. In addition to record net farm income, farm wealth is also at record levels. This book discusses the USDA's Economic Research Service (ERS), which originally developed a farm typology that has been used over the years extensively in ERS publications and USDA analyses to help clarify the distributional impacts of policy, market, and technological developments.
