Africa
By 2050, one in four humans will live in Africa. The median age on the continent is under 20 — the median age in Europe is over 40. Whatever your view on the next 25 years of the global economy, this is the demographic that will define it.
The numbers nobody quotes correctly
The population doubling-by-2050 stat gets repeated everywhere. Less quoted: the urbanization rate. Lagos alone is on track to pass 30 million people by 2050, which would make it bigger than the entire Greater Tokyo region today. Kinshasa will be close behind. That's not "growing cities" — that's building new infrastructure for ten Torontos and doing it in places where the existing power grid drops out three times a day.
If you're traveling there for work, you bring your own backup. A portable power station is not a luxury, it's the difference between working from your hotel and losing a day.
Where the real money is going
Three sectors are absorbing most of the inbound capital right now: mobile money, off-grid solar, and last-mile logistics. M-Pesa proved you could leapfrog Western banking infrastructure entirely; everyone is now trying to repeat that trick in fintech, insurance, and lending. The off-grid solar piece is the underrated one — a complete solar panel kit at $400 retail in the U.S. enables a small business in rural Kenya to charge phones, run a fridge, and stay open after dark. That's a category that didn't exist twelve years ago.
Last-mile logistics is the third wave. The road network is genuinely terrible in most of the continent — World Bank numbers say only about a third of rural Africans live within 2km of an all-weather road. Companies that figure out how to move goods the last fifty kilometers using motorcycles, boats, and informal driver networks are eating margins that Western logistics firms can't touch.
The infrastructure gap people get wrong
Power, not roads. Or rather, power before roads. A factory that loses production three times a day to outages cannot compete on cost no matter how good the road network is. South Africa's ongoing load-shedding crisis is the headline example, but Nigeria, Ghana, and most of sub-Saharan Africa have variants of the same problem. The fix isn't another mega-dam — it's distributed generation, batteries, and grids that can island-mode during disruptions.
If you're shipping into the continent, factor it in. Anything that depends on cold chain dies fast. A reliable 12V portable refrigerator for clinic samples or vaccine runs is worth more than the dollar price tag suggests.
Trade and the AfCFTA
The African Continental Free Trade Area, signed by 54 countries, is supposed to be the largest single market on the planet by member count. In practice, intra-African trade is still under 20% of total trade — the continent exports raw materials out and imports finished goods in. Changing that ratio is the project of the next two decades.
Anyone doing business there needs paperwork that travels. A multi-document travel wallet with carbon-copy slots for customs forms saves you at every border crossing.
What to actually pay attention to
Three signals. First, where Chinese loan-financed infrastructure is and isn't getting paid back — the renegotiations tell you which projects had real economics behind them. Second, which African countries are signing payment-system interop deals (PAPSS is the one to watch). Third, mobile data prices per gigabyte. The countries with the cheapest mobile data have the fastest startup formation rates and the most plausible growth paths.
The continent is not one story. It's 54. The investors who pretend otherwise lose money.
