The March 2019 total nonfarm payroll employment level was revised downward by 505,000, or −0.3 percent, not seasonally adjusted from the previously published level.
This year's benchmark revision was impacted by a data reconstruction in rail transportation, CES series 43-482000. After accounting for this data reconstruction, the benchmark error is −489,000, or −0.3 percent, not seasonally adjusted.
Over the prior 10 years, absolute benchmark revisions have averaged 0.2 percent, with an absolute range from less than 0.05 percent to 0.7 percent. Benchmark revisions are a standard part of the payroll survey estimation process. The benchmark adjustment represents a once-a-year re-anchoring, based on March data, of sample-based employment estimates to full population counts available through Unemployment Insurance (UI) tax records filed by nearly all employers with State Workforce Agencies.
