Methodology Improvements

With the release of January 2009 data on March 10, 2009, BLS implemented improvements to the methodology used to generate estimates of hires, separations, and job openings from the Job Openings and Labor Turnover Survey (JOLTS) program. These changes were designed to improve the measurement of hires, separations, and openings and to more closely align the hires and separations estimates with monthly employment change as measured by the BLS Current Employment Statistics (establishment) survey. All JOLTS historical series were revised to incorporate the new methods. For general information about the improvements in our methodology, please see (www.bls.gov/jlt/methodologyimprovement.htm).
