Estimated employment change and turnover for an occupation for a given year. Openings are a combination of two types of data:
- Job Growth an employer experiences greater demand for its products and hires new employees to increase production. If job growth is zero or negative, any and all openings are due to replacement needs.
- Replacement Needs an employer hires replacement workers for employees who leave the workforce or change occupations. Replacement rates are derived from national ten-year, occupation-specific percentages published by the BLS Employment Projections (EP) program.
Beginning with its 2017.3 datarun, Emsi uses the new BLS “Separations” methodology in its calculation of replacements. The BLS updated its methodology because the old methodology (called “Replacements”) significantly undercounted the number of workers leaving occupations. This resulted in an artificially low number of replacement jobs. The BLS’s new methodology corrects the deficiency and provides a better estimate of true replacement needs.
A combination of both new jobs and replacement jobs constitutes total openings. The annual openings figure is derived by dividing total openings by the number of years in the user’s selected timeframe. For example, an occupation showing 130 openings between 2016 and 2026 would result in an annual openings figure of 13.
