Informal Economy

The informal economy is the economic activity of workers and businesses that are not covered, or not adequately covered, by formal arrangements such as registration, tax, labour law and social protection. Most of it is legal work done outside those systems.

Also called: informal sector · informal employment · shadow economy · grey economy

The definition comes from the International Labour Organization, and its 2015 Recommendation No. 204 on the transition from the informal to the formal economy sets it out for policy. The ILO separates two things: informal enterprises, which are unregistered or very small, and informal jobs, which lack legal and social protection and can exist inside registered firms. A street vendor is informal on both counts; a cleaner paid off the books by a registered company holds an informal job in a formal firm.

The scale is large. The ILO's 2018 statistical study estimated that about two billion people, 61 percent of the world's employed population, worked informally, with the share far higher in low-income countries. Informal does not mean illegal. Most informal activity produces lawful goods and services; it is simply unregistered, untaxed or unprotected. Crime is a separate category, though the two can overlap.

Informal activity is not necessarily missing from GDP. National statisticians aim to measure all production and use surveys and estimates to capture much of it, as the IMF's work on measuring the informal economy explains.

Money is where informality is most visible. Informal businesses run on cash, on mobile money and on informal transfer systems. Digital payments create a record, which can help a business prove income and gain credit, and which also makes it visible to the tax authority. That trade-off is why financial inclusion and formalisation tend to be discussed together, and why formalisation works best when it offers something in return.

In practice

Estimates of the informal economy vary widely with the definition and method used. Figures for employment, output and the "shadow economy" measure different things and should not be compared directly.
