Technical notes contain detail on how we create our data and short explanations of our concepts. For additional published articles on concepts and measurement see Articles and Research. Additionally, the BLS Handbook of Methods presents detailed explanations of how the Bureau of Labor Statistics (BLS) obtains and prepares the economic data it publishes.

Total Factor Productivity
The BLS Productivity program replaced the term multifactor productivity (MFP) with total factor productivity (TFP) beginning with the 2020 data release. This was a change in terminology only and does not affect the data or methodology. The use of the term total factor productivity will improve the visibility and accessibility of our data and was accompanied by changes to the BLS website and future productivity news releases.
