U.S. Jobs Report: Unfavorable but Unbiased

Revelrous college students joke that Thursday night is the start of the weekend. We do not have that luxury, especially with the first Friday of each month offering the U.S. jobs report, bright and early. For a run of several years, this has been a cause for its own sort of celebration, with job gains continually exceeding expectations. Last week’s report abruptly ended the party, with disappointing payroll gains and significant negative revisions to prior estimates. The cooler data sparked a backlash. How did the music die so rapidly?

The monthly Employment Situation Summary combines the results of two concurrent surveys: The Current Establishment Survey (CES) collects staffing data from businesses, and the Current Population Survey (CPS) asks households about their employment status. Robust statistical methods are used to extrapolate national trends from a representative sample.

Every CES report includes revisions to the prior two months. Not all employers submit their responses by the initial deadline. Since the COVID-19 disruption, a declining proportion of businesses have replied on time. Smaller businesses in particular struggle to spare the resources to complete the surveys, and they are an important source of new jobs. This widening gap requires more use of estimation. The smaller the sample, the greater the margin of error.

Estimating employment at small firms is further complicated by their lifecycle: every day, new businesses are formed while others cease operations. Sound data on business births and deaths is naturally lagged. Annually, the estimate of employment is revised to incorporate a complete census of employers, which has revealed an overestimate of the level of employment in recent years. While these revisions have not changed the direction of the trend (showing growth both before and after revision), the restatements have revealed that initial CES numbers were too rosy.
