CES Benchmark Announcement

The March 2017 total nonfarm payroll employment level was revised upward by 138,000, or 0.1 percent, not seasonally adjusted from the previously published level.

This year's benchmark revision was impacted by a data reconstruction in CES series 60-561613 security guards and patrols and armored car services. After accounting for this data reconstruction, the benchmark error is 135,000, or 0.1 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.
