I'm looking for a U.S. government data source that provides detailed or "raw" job titles alongside the usual standardized occupations (e.g. Census, SOC, or O*NET occupation codes). Here's the catch: There must be some indication of how many people are in each job-title/code pair.
I'm aware of various match files and indexes that pair standardized codes with more detailed job titles, but none of them give a hint about the relative frequency of each title within each code (respondent count, or individual weighted records), which is really what I'm after.
The reason I ask for a government source is that I want the results to be as close to an unbiased random sample as possible.
