Claim under review
“80% of jobs are found through networking.”
Short answer
We could not trace this figure to any study that measures it. The pages that repeat it cite other pages, and where a source is named it is usually either a non-random online poll or Mark Granovetter's 1974 study, which measured something different in a much narrower population. There is a real and serious research literature showing personal contacts matter in job finding; the specific 80% figure is not part of it. Treat the number as unsourced while treating the underlying idea as well founded.
Evidence status
We could not trace the claim to any identifiable primary source. This is a statement about the evidence, not about the world: an unverified claim is not thereby false, it is unsupported, and we say so rather than guessing.
What we found
Following the citation chain from pages that repeat the figure leads to other advice pages, to an informal online poll with no random sampling, or to nothing at all.
Granovetter's 1974 study is the work most often invoked. It sampled 457 professional, technical and managerial men in one affluent Massachusetts suburb who had recently changed jobs, and found personal contacts were the predominant way they learned about the job they took.
That study measured how people found out about a job, which is not the same as how employers filled it, and its population is far narrower than 'all jobs'. Neither the population nor the measure supports a general figure for the labour market.
We deliberately do not publish a percentage from Granovetter here. The figures quoted for it vary between secondary sources and we did not verify one against the book's own tables. A review whose purpose is to stop unverified numbers circulating should not introduce one.
Earliest appearance we could trace
Not established. The figure appears in career-advice literature already treated as settled, without a citation we could follow to a measurement.
What was actually measured
- What was measured
- For the claim itself, nothing we could locate. The nearest real study measured how a specific group of job changers learned about the job they accepted.
- Population
- The claim states none. Granovetter's population was professional, technical and managerial men in one town.
- Sample
- No sample exists for the 80% figure; Granovetter sampled 457 men.
- Time period
- The claim states none; Granovetter's fieldwork was around 1969–1970.
What the evidence supports
- That personal contacts are an important route to job information, which is well established.
- That informal channels were the predominant route in at least one carefully studied group.
What it does not support
- That 80%, or any specific proportion, of jobs are obtained through networking.
- That a figure from professional men in a 1970s Massachusetts suburb generalises to today's labour market.
- That formal applications are futile. The claim is often deployed to imply this, and no evidence we found supports it.
Limitations
- The absence of a source does not mean no such study exists; it means we could not find one, and neither could the pages repeating the figure.
- Measuring this well is genuinely hard, because 'found through networking' is defined differently by almost everyone who measures it.
Jobsearch.ing interpretation
Our reading, marked as ours. Take the evidence above and reject this if you read it differently.
This claim is the clearest example in our library of a real finding being flattened into a round number. Contacts matter — that survives scrutiny. The 80% does not, and it is the part everyone quotes.
The practical cost is real. A job seeker who believes formal applications account for a fifth of hiring will allocate their time accordingly, on the strength of a number nobody has verified.

Getting a Job: A Study of Contacts and CareersSupports
Personal contacts were the predominant route to job information among professional men in one Massachusetts town.
Does not
It cannot support a general figure for how many jobs are filled through networking today.
Evidence details
- Supports (full)
- In a study of professional, technical and managerial men in Newton, Massachusetts who had changed jobs within the previous five years, personal contacts were the predominant way respondents learned about the job they took, and contact-found jobs tended to pay better than those found by formal means.
- Does not support (full)
- It does not support any claim about the proportion of jobs filled through networking across the whole labour market, in any country, at any later date. The study covers professional, technical and managerial men in a single affluent American suburb around 1970, and it measured how people learned about a job rather than how employers filled one.

- Random sample survey with follow-up interviews, examining how respondents obtained information leading to their current job.

- Version read
- Bibliographic and abstract records for the 1974 first edition and the 1995 second edition; the book's full text was not consulted directly for this review
- Notes
- We have deliberately not published a percentage from this study. The commonly quoted figures vary between sources and we did not verify one against the book's own tables; a review that exists to stop unverified numbers spreading cannot add one of its own.
