Total Factor Productivity
From Bureau of Labor Statistics, the agency that gathers this data: "Total factor productivity is defined as output per unit of combined inputs. TFP shows the relationship between changes in real sectoral output and changes in the combined inputs of capital input (K), labor input (L), and intermediate inputs (energy (E), materials (M), and services (S)) used in production of final goods and services. It reflects economic growth that is not due to growth in measured KLEMS inputs, including technological change, organizational changes in the production process, and other efficiency improvements.
