Key Takeaways
- • The U.S. Bureau of Labor Statistics issued a preliminary benchmark revision to March 2026 nonfarm employment of -79,000 (-0.1 percent), reflecting downward adjustment to previously reported job creation figures.
- • Private employment revisions were steeper, with total private employment revised down by -178,000 (-0.1 percent), indicating measurement discrepancies between preliminary estimates and comprehensive unemployment insurance tax records.
- • The preliminary benchmark revision serves as a measure of cumulative error in Current Employment Statistics (CES) estimates from March 2025 through March 2026, derived from the Quarterly Census of Employment and Wages (QCEW).
- • Final benchmark revisions will be released in February 2027 alongside the January 2027 Employment Situation report, with historical 10-year average absolute revisions at 0.2 percent of total nonfarm employment.
- • Individual industry sector revisions showed larger percentage adjustments than the aggregate nonfarm total, reflecting greater statistical sampling error at detailed industry levels compared to aggregated data.
Summary
The U.S. Bureau of Labor Statistics announced on August 28, 2026, a preliminary benchmark revision to total nonfarm employment for March 2026 of -79,000 jobs, representing a -0.1 percent downward adjustment to previously reported employment levels. The revision was based on a comparison between the Current Employment Statistics (CES) preliminary estimates and comprehensive employment counts derived from the Quarterly Census of Employment and Wages (QCEW), which pulls data primarily from state unemployment insurance tax records filed by nearly all employers.
The preliminary benchmark revision carries particular significance for private employment data, which was revised downward by a larger margin of -178,000 (-0.1 percent). This discrepancy between the two independent employment measurement methodologies reflects inherent sources of error in both the monthly CES survey estimates and the comprehensive quarterly census data. The preliminary revision measures the accumulated error in CES employment estimates across the 12-month period from March 2025 to March 2026.
The BLS noted that individual industry sectors within the benchmark revision showed larger percentage revisions than the aggregate nonfarm employment total, a pattern consistent with historical precedent. This divergence occurs because statistical sampling error increases at more granular industry levels compared to the reduced sampling error in aggregated national employment figures. The final benchmark revision—typically subject to additional refinement—will be released in February 2027 coinciding with publication of the January 2027 Employment Situation report. Historically, over the preceding 10 years, benchmark revisions averaged 0.2 percent of total nonfarm employment in absolute terms.
