Shortage Without Mobility: Labour Supply Has Become a Property of Place
Regional labour gaps in the OECD no longer close through workers moving, so shortage and slack coexist inside single countries, with consequences for site selection, workforce planning and migration policy through 2030.
The consensus on labour supply in the rich world runs through national taps: cut migration or open it, lift participation, hope automation covers the rest. The OECD's July report points at a different constraint. Adjustment inside countries has largely stopped running through people moving. Regional employment gaps persist because workers do not relocate at anything close to the speed required, and local shocks are absorbed through joblessness rather than reallocation. Acute shortage and durable slack now sit a two-hour drive apart and neither clears the other. The decision this forces is not whether to hire but where.
Signal Identification
A shift in how labour markets adjust rather than a fresh shock. The mechanism assumed to clear local imbalance, workers moving from slack places to tight ones, has weakened past the point where it does the work attributed to it. That is a failure of mechanism, not of the cycle, and it sits underneath the argument about migration caps and skills funding.
What's Changing
The OECD's 2026 Employment Outlook puts a number on the gap mobility is meant to close. The average employment-rate gap between top- and bottom-quintile regions inside one country is 11.4 percentage points, while the flows that would erode it are trivial: low-employment regions lose 0.25% of their population a year to net internal outmigration, high-employment regions gain roughly 0.15% (OECD, 07/07/2026). People move toward work far too slowly for mobility alone to reduce disparities.
National statistics carry the same split. In March to May 2026 UK unemployment ran from 1.8% in Northern Ireland to 6.5% in London (Office for National Statistics, 21/07/2026). April US state jobless rates ran from 2.2% in South Dakota to 6.2% in the District of Columbia against a national 4.3% (US Bureau of Labor Statistics, 22/05/2026). At city scale it widens: against a UK rate of 75.4%, employment ran from 63.7% in Blackburn to 85.5% in Worthing, while the country slackened to around 5.4 jobseekers per vacancy (Learning and Work Institute, 21/07/2026).
Europe shows the same coexistence by occupation: around a quarter of employment, 53 million workers, sits in occupations in widespread shortage or surplus, often the same occupation short in one country and surplus in another (European Labour Authority, 08/06/2026). The national tap is closing meanwhile: US net international migration is projected to fall from nearly 2.7 million in 2024 to 321,000 by mid-2026, down nearly 90% (Indeed Hiring Lab, 21/05/2026).
One national rate, four labour markets

Disruption Pathway
The pathway runs in three stages. Now, employers absorb the mismatch through wages and vacancy duration in tight places and longer unemployment spells in slack ones, the cost showing up as unfilled posts rather than visible policy failure. Through 2027-2028 the adjustment shifts from labour to capital: rather than recruit workers to sites, firms move sites to workers, surfacing in plant, warehouse and clinical-service decisions made on local participation rather than land price. From 2029 policy follows the capital, as nationally-set migration and skills instruments fragment toward regional visa quotas and devolved employment budgets.
Stress concentrates at three points. Housing first: the high-employment regions that need workers are those where housing cost blocks entry, so a tight market prices out its own remedy. Public services second, because care, health and education demand is anchored to where people live while supply is bid away by regions that pay more. Third, the firm's footprint, where a multi-site employer finds its scarce and surplus roles in different markets with no way to trade between them. Two adaptations follow: workforce planning moves from national headcount to a labour-catchment view, each site scored on supply within commuting distance; and pay bands fragment by geography as national scales turn unaffordable in tight regions and uncompetitive in slack ones.
Why This Matters
Three planning assumptions break together. First, that a national unemployment rate describes the labour a business can reach: the spreads across US states and UK cities say otherwise. Second, that migration policy is the lever for shortage: the US inflow has fallen nearly 90% in two years without closing a single regional gap, and would not have reached those gaps had it moved the other way. Third, that pay solves local scarcity: where housing cost binds, higher pay is competed away before it reaches supply. Boards and CFOs should give labour catchment the standing of energy cost and tax in site selection. Public commissioners face the mirror image: services planned nationally, staffed locally, failing by region.
Decision-action posture for this signal: Prepare — the mismatch is measurable now but siting and policy responses land in 2027-2030 planning rounds, so build labour-catchment analysis into location decisions and commit capital when sub-national migration or skills instruments appear.
Counter-Argument
The strongest objection comes from the same OECD chapter. Over time, regional gaps have been closing rather than widening: 21 of the 29 countries with regional employment data traceable to the early 2010s show lagging regions catching up and disparities narrowing (OECD, 07/07/2026). The European Labour Authority adds that an occupation short in one country and surplus in another indicates untapped potential for cross-border matching (European Labour Authority, 08/06/2026). On that reading mobility is slow but working, and the answer is to remove friction.
Relative convergence is compatible with gaps wide enough to defeat operational planning: an average gap of 11.4 percentage points is a hiring problem whether or not it narrowed after 2014. And the friction being removed is not the friction that binds. Remote work has not moved people: fully remote jobs are 12% of workers, and hybrid work keeps the rest tethered to metropolitan markets (University of Birmingham, 16/06/2026).
Implications
This catalyses durable change in where work is located, not in how much labour exists. The inflection window is 2027-2030, when siting decisions taken on labour-catchment grounds harden into fixed assets and sub-national instruments either appear or visibly fail to. Regions with young populations and affordable housing gain; high-wage regions with closed housing markets and depopulating regions with no employer base both lose. The immobility is long-running: Brookings demographer William Frey describes a fall from about one-fifth of Americans moving each year in the 1950s to roughly 9% now (Marketplace, 30/03/2026). What is new is that it binds.
Early Indicators to Monitor
- New regional visa quotas, provincial nominee schemes or depopulation-area work permits in the UK, Canada, Korea or Japan.
- Site announcements citing labour availability, not land cost, as the deciding factor.
- Employers shifting from national pay scales to explicit geographic bands in remuneration reports.
- OECD, ONS and Eurostat releases showing the regional employment spread holding or widening through 2027.
- Skills funding tied to travel-to-work areas rather than sectors.
Disconfirming Signals
- US Census geographic-mobility or ONS internal-migration estimates rising materially for two consecutive years.
- Regional employment and unemployment spreads narrowing sharply in successive OECD or Eurostat releases.
- Fully remote work rising well above its current share, with evidence of inter-regional relocation rather than commuting-belt moves.
- EURES or equivalent cross-border matching measurably clearing occupations recorded as short and surplus at once.
- Large employers consolidating onto fewer sites in tight markets while still filling vacancies at pre-2024 speed.
Strategic Questions
- Which sites sit in catchments that cannot supply your scarce roles at any realistic wage?
- Should the next capital commitment be sited on labour availability rather than land cost?
- At what threshold does labour catchment become a board-level decision rather than a planning input?
