The March 2014 Total nonfarm payroll employment level was revised upward by 67,000, or less than 0.05 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 0.1 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.
