The program surveys approximately 1.1 million establishments over a three-year period, making it the largest employer survey conducted by the BLS.

OEWS Survey Methodology

  • •Industry coverage: Nonfarm establishments across all industries except self-employed workers

Supplementary Data Sources

Our career guides and analysis also reference supplementary data sources to provide comprehensive career insights:

Glassdoor

Self-reported salary data from current and former employees. Useful for understanding company-specific compensation and total compensation breakdowns including bonuses, stock options, and benefits. We use Glassdoor data to supplement BLS statistics with company-level insights and recent market trends.

Payscale

Crowdsourced compensation database with detailed information on how skills, certifications, and experience affect pay. Payscale's methodology includes normalization for cost of living and provides granular insights on salary factors that BLS aggregate data doesn't capture.

LinkedIn Salary

Compensation data from LinkedIn's 900+ million members. Particularly valuable for technology and professional roles with strong LinkedIn presence. Provides insights on salary by company size, years of experience, and specific skills.

H1B Visa Salary Database

Public disclosure data from H1B visa applications provides exact salary information for specific roles at specific companies, particularly valuable for technology positions. This is actual wage data that employers must submit to the Department of Labor.

How We Present Data

Salary Statistics Explained

On each salary page, you'll see several statistical measures. Here's what they mean:

Median (50th Percentile)
The middle value - half of workers earn more, half earn less. This is typically the most representative measure of "typical" salary for an occupation.
25th Percentile
25% of workers earn less than this amount. Often represents entry-level or less experienced workers in the field.
75th Percentile
25% of workers earn more than this amount. Often represents experienced workers or those with specialized skills.
10th and 90th Percentile
The extreme ends of the salary distribution. The 10th percentile shows what the lowest-paid 10% earn, while the 90th percentile shows what the highest-paid 10% earn.
Employment Count
The estimated number of people employed in this occupation in the geographic area. Helps understand job availability and market size.

Data Update Frequency

BLS releases new OEWS data annually, typically in March or April, reflecting wages from May of the previous year. We update our database within 30 days of each new BLS release to ensure you have access to the most current official salary data available.

Limitations and Disclaimers

Important Considerations

  • Individual variation: Your actual salary may differ from these statistics based on your specific experience, education, certifications, negotiation skills, and employer.
  • Time lag: BLS data reflects wages from May of the reference year and is published 10-11 months later. Recent market changes may not be reflected.
  • Base salary only: BLS data reflects base wages and does not include bonuses, stock options, benefits, or other forms of compensation.
  • Suppressed data: BLS suppresses data for areas where sample sizes are too small to produce reliable estimates. If we don't show data for a location/occupation combination, it's because BLS doesn't publish it.

Using Salary Data Responsibly

We provide this salary information to help you make informed career decisions, but we strongly recommend:

  • Use multiple sources: Cross-reference BLS data with Glassdoor, Payscale, LinkedIn, and professional networks to get a complete picture.
  • Consider total compensation: Factor in bonuses, equity, benefits, PTO, and non-monetary perks when evaluating job offers.
  • Account for cost of living: A $100,000 salary in San Francisco has very different purchasing power than $100,000 in Nashville.
  • Talk to people in the field: Connect with professionals in your target role to understand real-world compensation and career progression.

Why We Use BLS Data

While many salary websites rely on crowdsourced or self-reported data, we chose to build SalaryMetroprimarily on Bureau of Labor Statistics data for several important reasons:

Scientific Methodology

BLS uses rigorous, scientifically-designed survey methodology with stratified random sampling to ensure statistically valid estimates. Self-reported data on other sites can be skewed by who chooses to submit their salary.

Employer-Verified Data

BLS surveys employers directly about their payroll, not employees recalling their salary. This eliminates errors from memory, misunderstanding of compensation, or intentional inflation/deflation of reported wages.

Massive Sample Size

With 1.1 million establishments surveyed over a three-year cycle, BLS data represents the most comprehensive occupational wage collection effort in the United States. This scale ensures reliable estimates even for less common occupations.

Standardized Definitions

BLS uses the Standard Occupational Classification (SOC) system, ensuring consistent definitions of job titles across all data. When you look up "Software Developer" on our site, it means exactly the same thing as in any other BLS-based resource.
