The monthly “Employment Situation” report from the Bureau of Labor Statistics (BLS) is closely watched by economists, investment analysts, and Federal Reserve policymakers. Many economists believe that the payroll employment data from the report is the best single indicator of the current state of the economy.
Most economists, inside and outside of the government, accept the dates determined by the Business Cycle Dating Committee of the National Bureau of Economic Research (NBER) for when a recession begins and ends. Although that committee takes into account a variety of macroeconomic data series, the peak of a business cycle as determined by the committee almost always corresponds to the peak in payroll employment and the trough of a business cycle almost always corresponds to the trough in payroll employment.
One drawback to relying too heavily on payroll employment data in gauging the state of the economy is that the data are subject to—sometimes substantial—revisions. As the BLS explains: “Monthly revisions result from additional reports received from businesses and government agencies since the last published estimates and from the recalculation of seasonal factors.” The revisions can be particularly large at the beginning of a recession.
For example, the following figure shows revisions the BLS made to its initial estimates of the change in payroll employment during the months around the 2007–2009 recession. The green bars show months for which the BLS revised its preliminary estimates to show that fewer jobs were lost (or that more jobs were created), and the red bars show months for which the BLS revised its preliminary estimates to show that more jobs were lost (or that fewer jobs were created).
For example, the BLS initially reported that employment declined by 159,000 jobs during September 2008. In fact, after additional data became available, the BLS revised its estimate to show that employment had declined by 460,000 jobs during the month—a difference of 300,000 more jobs lost. As the recession deepened between April 2008 and April 2009, the BLS’s initial reports underestimated the number of jobs lost by 2.3 million. In other words, the recession of 2007–2009 turned out to be much more severe than economists and policymakers realized at the time.
The BLS also made substantial revisions to its initial estimates of payroll employment for 2020 and 2021 during the Covid pandemic, as the following figure shows. (Note that this figure appears in our new 9th edition of Macroeconomics, Chapter 9, Section 9.1 (Economics, Chapter 19, Section 19.1 and Essentials of Economics, Chapter 13, Section 13.1).)
The BLS initially estimated that employment in March 2020 declined by about 700,000. After gathering more data, the BLS revised its estimate to indicate that employment declined by twice as much. Similarly, the BLS’s initial estimates substantially understated the actual growth in employment from August to December 2021. After gathering more data, the BLS revised its estimate to indicate that nearly 2 million more jobs had been created during those months than it had originally estimated.
Just as the initial estimates for total payroll employment are often revised by sutbstantial amounts up or down, the same is true of the initial estimates of payroll employment in individual industries. Because the number of establishments surveyed in any particular industry can be small, the initial estimates can be highly inaccurate. For instance, Justin Fox, a columnist for bloomberg.com recently noted what appears to be a surge in employment in the “sports teams and clubs” industry. As the following figure shows, employment in this industry seems to have increased by an improbably large 75 percent. Was there a sudden increase in the United States in the number of new sports teams? Certainly not over just a few months. It’s more likely that most of the increase in employment in this industry will disappear when the initial employment estimates are revised.
One source of data for the BLS revisions to the monthly payroll employment data is the BLS’s “Quarterly Census of Employment and Wages.” The QCEW is based on the reports required of all firms that participate in the state and federal unemployment insurance program. The BLS estimates that 95 percent of all jobs in the United States are included in the QCEW data. As a result, the QCEW surveys about 11.9 million establishments as opposed to the 666,000 establishments included in the establishment survey.
The BLS uses the QCEW to benchmark the payroll employment data, which reconciles the two series. The BLS makes the revisions with a lag. For instance, the payroll employment data for 2023 won’t be revised using the QCEW data until August 2024. Looking at the 2023 employment data from the two series shows a large discrepancy, as seen in the following figure.
The blue line shows the employment data from the establishment survey and the orange line shows the data from the QCEW survey. (Both series are of nonseasonally adjusted data.) The values on the vertical axis are thousands of workers. In December 2023, the establishment survey indicated that a total of 158,347,000 people were employed in the nonfarm sector in the United States. The QCEW series shows a total of 154,956,133 people were employed in the nonfarm sector—about 3.4 million fewer.
How can we interpret the discrepancy between the employment totals from the two series? The most straightforward interpretation is that the QCEW data, which uses a larger sample, is more accurate and payroll employment has been significantly overstating the level of employment in the U.S. economy. In other words, the labor market was weaker in 2023 than it seemed, which may help to explain why inflation slowed as much as it did, particularly in the second half of the year.
However, this interpretation is not clear cut because the QCEW data are also subject to revision. As Ernie Tedeschi, director of economics at the Budget Lab at Yale and former chief economist for the Council of Economic Advisers, has pointed out, the QCEW data are typically revised upwards, which would close some of the gap between the two series. So, although it seems likely that the closely watched payroll employment data have overstated the strength of the labor market, we won’t get a clearer indication of how large the overstatement is until August when the BLS will use the QCEW data to benchmark the payroll employment data.
