This data set provides estimates of productivity growth in the U.S. farm sector for the 1948-2011 period, and estimates of the growth and relative levels of productivity across the States for the period 1960-2004.
Note that the national data series has been revised (see Findings, Documentation, and Methods for details), and updates of the State-level statistics are suspended in light of reduced ERS resources and the discontinuance of key source data series. The quality of the national statistics is preserved.
It is widely agreed that increased productivity is the main contributor to economic growth in U.S. agriculture. The level of U.S. farm output more than doubled between 1948 and 2011, growing at an average annual rate of 1.49 percent. Aggregate input use increased at a modest 0.07 percent annually in the same period, so the positive growth in farm sector output was very substantially due to productivity growth. But what exactly is productivity?
Single-factor measures of productivity, such as corn production per acre (yield or land productivity) or per hour of labor (labor productivity), have been used for many years because the underlying data are often easily available. While useful, such measures can also mislead. For example, yields could increase simply because farmers are adding more of other inputs, such as chemicals, labor, or machinery, to their land base. USDA produces measures of total factor productivity (TFP), taking account of the use of all inputs to the production process.
Specifically, annual productivity growth is the difference between growth of agricultural output and the growth of all inputs taken together (methods for combining inputs are described in Findings, Documentation, and Methods). Productivity therefore measures changes in the efficiency with which inputs are transformed into outputs. USDA also produces State-level productivity measures-annual productivity growth rates as well as cross-State differences in levels of productivity, or differences in output per unit of combined inputs. Input measures are adjusted for changes in their quality, such as improvements in the efficacy of chemicals and seeds, changes in the demographics of the farm workforce, or innovations in machinery design. As a result, agricultural productivity is driven by innovations in onfarm tasks, changes in the organization and structure of the farm sector, research aimed at improvements in farm production, and/or random events like weather.
