The integrity and accuracy of national economic data are paramount for policymakers, businesses, and the public, yet their compilation is an inherently complex process involving ongoing adjustments. This inherent dynamism was recently underscored by President Donald Trump’s decision to terminate Bureau of Labor Statistics (BLS) Commissioner Erika McEntarfer. The move followed a weaker-than-expected July jobs report and substantial downward revisions to prior months’ figures, igniting a public discussion about the methodologies employed by the agency in measuring the U.S. workforce.
- BLS Commissioner Erika McEntarfer was terminated by President Donald Trump.
- The termination followed a July jobs report indicating a gain of 73,000 jobs, below the LSEG economists’ estimate of 110,000.
- Employment figures for May and June were simultaneously revised downward by a combined 258,000 jobs.
- President Trump publicly alleged that the Commissioner “faked the Jobs Numbers before the Election.”
- However, revisions to monthly jobs reports are a standard statistical practice integrated into the BLS’s survey process to enhance data precision.
The President’s assertion that the Commissioner “faked the Jobs Numbers before the Election” was made in the context of the BLS reporting a gain of 73,000 jobs in July, falling notably short of the 110,000 jobs estimated by LSEG economists. Furthermore, the agency had issued significant downward revisions, reducing May and June employment figures by a combined 258,000 jobs. While these figures drew public scrutiny, within established statistical practice, such revisions are a standard procedure, designed to enhance data precision as more comprehensive information becomes available over time. This foundational aspect of data collection warrants a deeper understanding of the BLS’s methodologies.
The Foundation of Labor Data
The BLS’s Current Employment Statistics (CES) survey serves as a cornerstone of U.S. labor market intelligence. As of June 2024, the U.S. economy encompassed over 12.2 million business establishments employing more than 155.7 million individuals. To accurately capture this vast and dynamic landscape, the CES survey contacts approximately 121,000 businesses and government agencies each month on a voluntary basis, representing about 631,000 individual worksites. This extensive reach establishes it as one of the largest monthly surveys conducted globally, a scale that inherently necessitates sophisticated data management and rigorous revision protocols.
The Methodological Imperative: Why Revisions Occur
The necessity of revisions in labor statistics stems from several factors inherent in large-scale data collection and economic modeling:
-
Quick Turnaround Times: The initial jobs report is compiled under exceptionally tight deadlines, with data collection typically spanning just 10 to 16 days, averaging 12 to 13 days. This compressed timeframe means some businesses, particularly those with less frequent payroll cycles, may not be able to submit their data before the initial reporting deadline.
-
Evolving Response Rates: The initial monthly jobs figure is always designated as a preliminary estimate. The BLS’s process incorporates two subsequent revisions in successive months as additional data is amassed. The average collection rate for the first publication of a given month’s employment levels was 68.3% between 2020 and 2023. This figure substantially improves for subsequent publications, rising to 89% for the second publication (the first monthly revision) and 92.8% for the third publication (the second monthly revision).
-
Correction of Non-Response & Sampling Error: The built-in monthly revisions provide crucial time for businesses and agencies that initially missed reporting deadlines to submit their data. Furthermore, respondents might initially submit incorrect information, which can later be identified and corrected during the revision process. As more samples are collected and reported, the overall quality of the data is enhanced through the reduction of reporting and non-response errors.
-
Seasonal Adjustments: The BLS applies seasonal adjustments to its data based on the most current monthly information, rather than relying on static forecasts. This methodology necessitates retrospective seasonal adjustments to previously reported data, ensuring that underlying economic trends are not obscured by predictable seasonal variations. The ongoing integration of new sample data also helps the agency reduce revisions and errors in annual data over time.
-
Annual Benchmarking: To counter the cumulative effects of non-response, reporting errors, and the continuous birth and death of firms, the BLS conducts an annual benchmarking process. This critical procedure re-anchors the survey sample to more current population data, effectively preventing employment estimates from drifting over time. The BLS benchmarks population counts for the month of March annually, with preliminary benchmarks typically released in early September and finalized in February of the subsequent year. For instance, the preliminary benchmark for March will be released in early September this year, with finalization in February 2026.
These systematic adjustments highlight that revisions are not anomalies but rather integral components of generating robust and accurate labor market statistics. They represent a commitment to refining data quality over time, a necessity given the scale and dynamic nature of the U.S. economy.
