Cost Estimator Openings to Employment Ratio, 2024 to 2034
Key stats
Projected annual openings equal about 7.6 percent of 2024 employment when 16,900 is divided by 221,400.
Contents
Key takeaways
- BLS projects 16,900 openings per year even as occupation employment declines 4 percent through 2034.
- BLS attributes the openings to occupational transfers and labor-force exits, not net growth.
- The 7.6 percent calculation is not a turnover rate and cannot predict company or construction vacancies.
Reconcile decline with openings
BLS projects employment moving from 221,400 in 2024 to 212,100 in 2034, a decline of 9,300, while averaging about 16,900 openings per year.
Both can occur because openings replace people who leave the occupation or labor force even when the occupation becomes smaller.
Bound the editorial ratio
Dividing annual-average openings by base-year employment gives about 7.6 percent. The numerator is a projection flow and the denominator is a point-in-time stock.
The result is not the vacant-job share, an employee departure probability, or a construction turnover rate.
Translate the signal carefully
Replacement demand makes documented assumptions, estimate histories, review checklists, and role coverage useful.
A succession review should name critical sectors, software, owner procedures, and review authorities. Company records determine action.
Key data table
Use this table as a review aid. The headline statistic is sourced directly; the interpretation rows explain how to apply it without treating a market benchmark as a project quote.

What the data can and cannot do
Public labor, spending, productivity, and price series provide a common baseline. They can reveal direction, scale, and unusual movement. They cannot identify the exact labor crew, subcontractor coverage, waste factor, access constraint, or escalation risk on a specific project.
A responsible estimate keeps the public benchmark separate from local bid history. Record the source date, geography, units, seasonal treatment, and any conversion before using the number in an estimate review.
How estimators should use it
- Use replacement scale to prompt succession, documentation, and cross-training reviews.
- Forecast hiring from known attrition, pipeline, role design, and local evidence instead of applying 7.6 percent to headcount.
Add a source note beside every adjusted rate. If the benchmark and recent quotes disagree, do not average them automatically. Investigate geography, scope, timing, units, and market segment first.
Data sources and methodology
The primary statistic is transcribed from the source identified in the source notes below. The additional links are a consistent reader reference set for broader labor, construction volume, productivity, and regional context. They do not support or alter the headline figure and are not presented as article-specific evidence.
- OEWS estimates describe wage and salary workers and exclude self-employed workers. The cost estimator occupation spans construction, manufacturing, and services.
- Survey estimates are subject to sampling and nonsampling error. Rounded values support only the displayed precision.
- Employment projections and OEWS estimates have different reference periods. Ratios joining them are editorial planning calculations, not BLS forecast rates.
Conservative convention: retain the published unit and date, avoid false precision, and treat national or sector data as a planning signal until local project evidence confirms it.
Frequently asked questions
Can this statistic set a project unit rate?
No. It can challenge or frame an assumption, but a project rate still needs current scope, geography, crew, productivity, supplier, and subcontractor evidence.
How often should the source be checked?
Check the primary release before a major estimate update and record the release or access date in the estimate notes.
Why are reader context sources included?
They give readers a consistent path to broader official construction and labor series. They are not evidence for the headline statistic and do not replace or alter its primary source.
Conclusion
Projected annual openings equal about 7.6 percent of 2024 employment when 16,900 is divided by 221,400. Use the figure as a documented benchmark, preserve the source date and units, and require project-specific evidence before changing a bid assumption.
