The Forgotten Economics of County Size
By Ibrahim K. Minyori
Maps have a peculiar way of distracting us.
When people discuss counties, their eyes instinctively drift towards boundaries. They debate where one begins and another ends. They argue over headquarters, names and historical identities. They defend familiar lines as though geography itself were the central question.
It rarely is.
Behind every administrative map lies another map that is invisible to the naked eye.
It is the map of money.
Of taxes.
Of investment.
Of infrastructure.
Of economic opportunity.
This hidden map often determines whether a county merely exists or truly thrives.
That is why county size is not simply a constitutional question.
It is an economic one.
Indeed, some of the most important arguments for reconsidering administrative boundaries have remarkably little to do with politics. They arise instead from a discipline that cares less about sentiment than sustainability.
Economics asks a stubborn question.
Can this institution pay for the future it promises?
The answer begins with the tax base.
Every government, national or local, survives upon the productive activity of its people. Shops open their doors. Farmers harvest crops. Factories manufacture goods. Hotels welcome tourists. Property changes hands. Businesses generate profits. Workers earn incomes.
Government does not create wealth simply by existing.
It organises, protects and redistributes wealth created elsewhere.
The broader the economic activity, the broader the tax base.
The broader the tax base, the greater the government’s capacity to invest.
This explains why two counties of similar population may possess radically different futures.
One may contain vibrant industries, universities, logistics hubs and thriving commercial centres.
The other may depend almost entirely upon subsistence agriculture or national transfers.
Both have governments.
Only one possesses substantial fiscal independence.
Constitutions can distribute political authority.
They cannot legislate prosperity into existence.
This is where county size quietly enters the conversation.
Larger economic regions naturally combine more businesses, more consumers, more workers and more investment opportunities into a single administrative unit.
The result is not merely a larger budget.
It is a more resilient one.
Economic diversity becomes a form of constitutional insurance.
If agriculture suffers, manufacturing continues.
If tourism declines, logistics remain active.
If one industry contracts, another cushions the shock.
Small economies often lack that luxury.
They rise and fall with far fewer pillars supporting them.
Investment follows similar logic.
Investors rarely ask the first question politicians ask.
They are less interested in historical boundaries than economic ecosystems.
They examine market size.
Transport networks.
Workforce availability.
Infrastructure.
Supply chains.
Regulatory stability.
Future growth.
A county containing an integrated economic corridor presents a different proposition from one divided across several competing administrations.
Businesses prefer certainty.
They prefer coordinated planning.
They prefer institutions capable of approving major projects efficiently.
They prefer governments large enough to think strategically rather than administratively.
This is not because investors dislike local government.
It is because capital naturally gravitates towards coherence.
Imagine an automobile manufacturer searching for a location.
It needs roads capable of supporting freight.
Reliable electricity.
Industrial land.
Water.
Skilled labour.
Housing.
Schools for employees’ families.
Efficient licensing.

Environmental approvals.
The investment is never just about one factory.
It is about the entire ecosystem surrounding it.
Larger counties often possess greater ability to assemble that ecosystem under a single strategic vision.
Infrastructure tells the same story.
Roads do not become valuable because they begin somewhere.
They become valuable because they connect somewhere.
Railways derive their importance not from stations but from destinations.
Water pipelines matter because they link reservoirs to communities.
Infrastructure is, by definition, connective.
Administrative fragmentation sometimes interrupts that connectivity.
Neighbouring counties may pursue competing priorities.
One builds a road to the border.
The next delays its continuation.
One develops an industrial zone.
The neighbouring administration emphasises unrelated projects.
Economic geography becomes divided by political geography.
Larger administrative regions reduce this friction.
Planning becomes regional rather than piecemeal.
Infrastructure begins following economic logic instead of constitutional coincidence.
This is one of the least appreciated advantages of scale.
Not bigger government for its own sake.
Better coordination.
Perhaps nowhere is this more evident than in metropolitan regions.
Cities rarely stop growing because county boundaries tell them to.
Commerce spills across borders.
Workers commute between jurisdictions.
Businesses establish supply chains that ignore administrative maps.
Housing expands outward.
Economic life becomes regional long before governance catches up.
Successful administrative systems recognise this reality.
They organise governments around economies rather than expecting economies to organise themselves around governments.
None of this means that every larger county automatically succeeds.
Scale creates opportunities.
Leadership determines whether those opportunities are realised.
A poorly governed large county can squander advantages that a well-governed smaller one uses brilliantly.
Institutional design is necessary.
Competence remains indispensable.
Yet constitutional design should maximise the probability of success.
It should create environments where prosperity becomes easier rather than harder.
This requires looking beyond politics.
The forgotten economics of county size reminds us that governments are not merely democratic institutions.
They are economic platforms.
They create conditions within which enterprise either flourishes or struggles.
Their boundaries influence investment decisions.
Their scale influences planning capacity.
Their fiscal strength influences service delivery.
Their economic integration influences competitiveness.
These relationships are rarely visible during election campaigns.
But they quietly shape prosperity for decades.
Perhaps this explains why mature democracies periodically reconsider their internal administrative structures.
The objective is not simply to redraw maps.
It is to redraw opportunity.
To ask whether today’s boundaries still correspond with today’s economies.
Whether yesterday’s administrative arrangements continue serving tomorrow’s ambitions.
Kenya’s constitutional conversation increasingly finds itself standing before precisely this question.
The issue is no longer whether devolution should exist.
It should.
Nor is the issue whether local representation matters.
It unquestionably does.
The deeper question is whether the economic foundations of counties are strong enough to sustain the developmental aspirations entrusted to them.
Because governments do not build prosperity through constitutional clauses alone.
They build it through productive economies, strategic investment and infrastructure that binds opportunity together.
Maps may define where counties begin.
Economics determines how far they can go.
And perhaps that is the most forgotten lesson of all.
A county’s greatest asset is not the line that surrounds it.
It is the economy that lives within it.
