The Population Fallacy: Why I'm Rethinking My Own Investment Narrative
“Torture the data, and it will confess anything” - Roland Coase
I’ll admit that I’ve used this demographic dividend pitch myself quite a lot. Africa will hit about 2.5 billion by 2050, with a median age of 19, and the world’s youngest population. This narrative often does the heavy lifting when we are raising capital from LPs.
But after investing millions of dollars over the last couple of years, I am increasingly convinced we may be engaged in sophisticated self-deceit. This demographic story is just a single story and ignores many other important variables.
What Does History Teach Us From Other Emerging Markets?
India’s Mixed Results:
India’s 1990s-2000s demographic dividend narrative was compelling, with hundreds of millions entering the working age. Yet decades later, the results are mixed: large portions of the working-age population remain underemployed or in informal sectors. The dividend required employability infrastructure, formal-sector job creation, and skills development that didn’t scale to keep pace with population growth, particularly in some regions.
Latin America:
Brazil’s population surge (1960s - 80s) was supposed to guarantee a developed status. Instead, the growth without transformation of infrastructure and industries led to bodies without opportunity and an eventual middle-income trap.
Population growth correlates with economic potential only when it is paired with systematic capacity building. Without it, you get demographic pressure, not prosperity.
How I’ve Seen This Play Out
I see this pattern repeating in the deals crossing my desk.
Market Sizing by Population Math: “Nigeria has 220 million people, so if we capture just 1%....”
Let’s ignore the fact that we still do not have a good estimate of the population of Nigeria, since we’ve not had a proper census in decades. This reasoning treats humans as interchangeable economic units, ignoring purchasing power, infrastructure access and the reality of distribution economics.
TAM Inflation: Population x Western ARPU = Fantastical addressable market
I see this reasoning constantly from African founders, and I understand why. When you’re building in infrastructure-constrained markets, the population story feels like the one undeniable asset; hinging all the growth on population without critically thinking about market depth, competitive dynamics, purchasing power, infrastructure deficit or operational complexity.
What This Matters
The population narrative isn’t wrong in itself; it just crowds out superior frameworks, in my opinion.
Specialisation Over Scale: Singapore built an outsized impact with 6 million people through strategic positioning, not demographic breadth,
Infrastructure Before Bodies: South Korea’s transformation began with deliberate infrastructure investments. The population amplified these; it didn’t replace them.
Quality over Quantity: Taiwan created more semiconductor value with 23 million people than countries with 10x the population.
Alternative Framework: What Actually Matters
This is really good advice to my African founders, so please take note:
Infrastructure Depth
What percentage of the claimed TAM has reliable internet/power/logistics?
Can your product actually reach your addressable market economically?
Capability Concentration
Where are pockets of specialised expertise emerging?
What unique data assets exist that can’t be replicated?
Demand Verification
Evidence of willingness to pay at sustainable price points
Unit economics that work without perpetual subsidy
Systemic Momentum
Which ecosystems demonstrate compound growth rather than linear expansion?
Africa’s population will continue to grow regardless of whether we build systems to make the growth economically transformative. Demographics create potential; they do not guarantee outcomes, as some of us can see.
The question we should be asking ourselves isn’t “How many people live here?” It’s “What systems exist to convert all that human potential into economic value?”
The times we’re in, with AI reshaping value creation and global capital becoming more selective, demand better thinking that “Africa is young, therefore returns”.
Until we answer the systems question, we’re not investing in building Africa’s future. We are just gambling on demographic determinism while calling it strategy. It might work, but we can increase the odds of it working if we take this different approach.
I’m as guilty as anyone. But the times we’re in demand better. Let’s build it together.
