Which Salary Surveys are Best for Freelance Consultants?


Hello Compensation and HR Professionals from LinkedIn,

(I had to post my question here because LinkedIn limits discussion posts to 200 characters...)

I am a labor economist seeking advice about salary survey data. I am looking into doing some consulting work helping individual employees negotiate their salaries, specifically determining what the market value for their skill sets are. 

To do so I need great data. I have been researching some options and was hoping this community of compensation professionals could provide some insight as to what data sources are the most credible and persuasive. 

I am looking for data on the national level, across all industries. I have looked at the following options, ranked according to how I think compensation professionals would value the quality of their data. How is this ranking? Which would you recommend I use? Is there a dataset I am missing?

1.      Mercer, Towers Watson, Radford, Hay: their national benchmark databases cost $20k+ and are out of my price range.

2.      Economic Research Institute’s Salary Assessor Tool: 5,600 benchmark classifications, data comes entirely from employer surveys conducted by ERI and validated against purchased surveys and datasets (Mercer, TW, etc. – they list which ones they purchase). Includes reliability statistics (standard error and # of observations) to meet Daubert Challenge criteria in court. Unlimited access to their costs $1k-3k annually.

3.      Kenexa’s (salary.com) CompAnalyst Tool: 4,500 benchmark classifications, data updated monthly. They purchase over 400 surveys each year, but they do not disclose which surveys. They do assure that all their surveys comply with World@Work standards and the DOJ/FTC Survey Safe Harbor Guidelines. Costs $3k-6k annually.

4.      Payscale.com’s MarketRate Tool: 13,000 benchmark classifications, data updated daily. Data comes from 4-5 million monthly visitors (employees) who fill out their surveys. Their data also adheres to World@Word standards. They benchmark their data with Towers Watson, Mercer, Hay, Radford and find that they are highly correlated (0.84). Unlimited access to their data costs $3k-6k annually. – do compensation professionals respect this data?

5.      B LS’s OES and NCS Surveys: 800 job classifications, survey conducted every six months, data usually lags one year. Limits pay data to $90/hour, so higher earners are excluded. Free.

6.      Indeed.com Salary Search: data from salary information extracted from 50 million+ job postings over the previous 12 months. Free.
 Thanks in advance for your insights!
