What it means
Even when there is a suitable vacancy for every job seeker, matching the two is not instant. Applications, interviews, notice periods and relocation all take weeks, and the people in that gap are counted as unemployed even though the labour market is functioning normally.
This matters for business planning because it sets a floor under the unemployment rate. Policymakers do not aim for zero unemployment, since some churn signals that people feel confident enough to leave jobs and that employers are hiring selectively rather than taking the first candidate available.
For employers, frictional unemployment is the reason a vacancy is never filled the day it opens. Recruitment lead times, and the cost of covering the gap, should be built into workforce plans rather than treated as a surprise each time somebody resigns.
The key distinction is against structural and cyclical unemployment. Structural unemployment means the available workers do not have the skills or are not in the places the jobs are, and cyclical unemployment means demand across the economy has fallen, whereas frictional unemployment resolves itself with time.
Frictional unemployment can be reduced but not eliminated, and reducing it too aggressively is not obviously good. Better job boards, clearer wage information and portable benefits shorten search times, but a very short search may push people into poor matches that they leave again quickly.
In practice
Real-world examples.
Example
A university system produces 40,000 graduates a year who take on average three months to find their first role. At any given moment roughly 40,000 x 3 / 12 = 10,000 of them are frictionally unemployed, a number that peaks each summer and falls by winter.
Example
A technology hub sees engineers routinely leave one employer for another with a six-week gap in between for travel and start dates. Local unemployment never falls below about 3% even when every firm is hiring, because the churn itself keeps people temporarily between roles.
Example
A manufacturer moves a plant from one region to another and offers relocation packages. Staff who accept still spend several weeks out of work during the move, adding to frictional unemployment in the old region without any jobs having been destroyed overall.
Formula
Calculation
Frictional Unemployment Rate = Frictionally Unemployed / Labour Force x 100
Consider an economy with a labour force of 8,000,000 people and 400,000 people unemployed. The headline unemployment rate is 400,000 / 8,000,000 x 100 = 5%.
A survey of those 400,000 finds that 160,000 left their last job voluntarily or are new entrants actively searching, with no skills or location mismatch involved. The frictional unemployment rate is therefore 160,000 / 8,000,000 x 100 = 2%.
That leaves 400,000 - 160,000 = 240,000 people, or 3% of the labour force, whose unemployment is structural or cyclical. Only that 3% is likely to respond to retraining or demand stimulus, which is exactly why the split is worth doing before any policy money is spent.Case study
Seen in the real world.
Calderport is an illustrative, fictional coastal city used to show the idea in numbers. Its labour force is 120,000 people and 6,000 are unemployed, a rate of 6,000 / 120,000 x 100 = 5%. Local officials assumed the whole figure reflected a weak economy and drafted a retraining scheme.
A closer look found that 3,000 of the 6,000 were between jobs by choice or entering the market for the first time, giving a frictional rate of 3,000 / 120,000 x 100 = 2.5%. Retraining would have done nothing for that half of the total, because those people already had skills employers wanted.
The city instead funded a shared vacancy platform and standardised job descriptions across large local employers, cutting average search time from ten weeks to seven. The frictionally unemployed count fell to 3,000 x 7 / 10 = 2,100, or 1.75% of the labour force, at a fraction of the cost of the retraining scheme it replaced.
Watch out
Common mistakes.
- Treating all unemployment as a sign of economic weakness, when a portion of it simply reflects normal movement between jobs.
- Confusing frictional with structural unemployment, and prescribing retraining for people whose only problem is that hiring takes time.
- Assuming frictional unemployment is bad and should be driven to zero, when some churn is a sign of a confident labour market.
Questions
People also ask.
Is frictional unemployment voluntary?
Largely yes, since it mostly covers people who chose to leave a role or are entering the market, though notice periods and slow hiring processes make the length involuntary.
Does it disappear in a boom?
No, it often rises slightly in a boom because more people feel safe resigning before they have secured the next role.
How does it relate to the natural rate of unemployment?
The natural rate is roughly frictional plus structural unemployment, the level that persists when the economy is neither overheating nor in recession.
