With the May 2021 estimates, the OEWS program now uses a new estimation methodology. The new model-based estimation methodology, called MB3, has advantages over the previous methodology, as described in the Monthly Labor Review article "Model-Based Estimates for the Occupational Employment Statistics program." Technical information is available in the May 2021 Survey Methods and Reliability Statement. Estimates for the years 2015-2020 were recalculated using the new estimation methodology and are available as research estimates.
