The March 2015 total nonfarm payroll employment level was revised downward by 199,000, or -0.1 percent, not seasonally adjusted from the previously published level. Over the prior 10 years, absolute benchmark revisions have averaged 0.3 percent, with an absolute range from 0.0 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 Employment Security agencies.
This year's benchmark revision was impacted by a data reconstruction in the services for the elderly and persons with disabilities industry (NAICS 62412). After accounting for this data reconstruction, the error is -172,000, or -0.1 percent, not seasonally adjusted. In addition, the CES total nonfarm over-the-year change on a not seasonally adjusted basis, after accounting for this data reconstruction and the new benchmark level, is 172,000 less than it was previously published.
