Most of the world clocks in every morning to a job that, on paper, barely exists. There is no payslip with a tax line, no entry in a national register, no quarterly filing — and yet the work is real, the hours are long, and the income, however modest, is what keeps the lights on. The strange part is not that this work happens. The strange part is how confidently economists discuss “the economy” while leaving most of it out of the frame.
The numbers are not a rounding error. According to the International Labour Organization, around two billion people — more than 61 percent of the global workforce — earn their living informally. That figure is not evenly spread. In Africa, informal employment reaches roughly 85.8 percent of all jobs, the highest share of any region on earth. For the majority of working humanity, informality is not the exception that proves the rule. It is the rule, and formality is the curiosity.
Picture the busiest stall in any market you have ever walked through. It has the longest queue, the fastest turnover, the regulars who know the vendor by name. It runs on cash, memory, and trust, and it has never printed a receipt in its life. Now picture the official market map drawn up by the city, the one used to plan roads and levy taxes and report growth to the capital. That stall — the one everyone actually visits — is simply not on it. The quiet kiosk three doors down, the one with a card machine and almost no customers, is mapped, labelled, and counted. The roaster doing the most business is the one nobody recorded.
This is not a quaint detail about street vendors. It is a measurement failure with teeth. Research summarised by the World Economic Forum, drawing on IMF estimates, puts informal output at an average of about 35 percent of GDP across low- and middle-income economies — against roughly 15 percent in advanced ones. When a third of national output sits outside the ledger, the headline GDP figure is not a precise reading of the economy. It is a confident estimate of the part that happened to leave a paper trail.
The consequences run straight through the policymaking that depends on those numbers. A finance minister setting interest rates, a central bank judging whether growth is overheating, an agency deciding where to route social spending — all are reading an instrument that systematically under-reports the largest segment of the labour force. The IMF has framed informality as a defining feature of developing economies rather than a temporary glitch on the road to formality, which means the gap is not closing on its own. Policies calibrated to the visible economy can miss, or actively harm, the invisible one — the one where most people actually work.
There is a behavioural pattern hiding in the omission, and it is an old one: we measure what is easy to measure and then mistake the measurement for the territory. The informal economy is hard to count precisely because it was built to operate without the apparatus that does the counting — no forms, no fixed address, no audited accounts. So it gets treated as background noise, a margin of error, a sector that will eventually “graduate” into the real thing. But a sector that employs 85 percent of a continent’s workers is not a margin. It is the centre, mislabelled as the edge.
The brief from the ILO’s own data snapshots is blunt: informality is where the majority of the world’s livelihoods sit, and it is dense precisely in the places where formal safety nets are thinnest. That combination — most people, least protection, least visibility — is exactly the one a serious economic model should refuse to ignore. Counting it better would not romanticise precarious work; it would simply stop pretending it isn’t there. You cannot protect, tax fairly, or plan around what you have decided not to see.
None of this means the spreadsheets are useless. It means they are partial, and that the part they leave out is the bigger one. The formal economy gets the press releases, the quarterly figures, and the neat lines on a chart. The informal economy gets the early starts, the cash, and most of the actual customers. The headlines will keep going to the polished, registered, fully-audited cup. But the main roast — the one that actually feeds most of the world — is brewing off the books, and has been all along.
