Statistics on the informal economy

Table of Contents


In many countries, informal employment represents a significant part of the economy and labour market and plays a major role in production, employment creation and income generation. However, informality puts workers at a higher risk of vulnerability and precariousness. Indeed, informality has a strong adverse impact on the adequacy of earnings, occupational safety and health and working conditions in general.

In the context of fragmented labour markets or insufficient social safety nets or where wages and/or working hours in formal jobs are low, workers may resort to informal employment. Thus, key labour indicators such as the unemployment rate and time-related underemployment would fail to convey a full picture of the labour market.

Statistics on informal employment provide valuable information on the quality of employment and are crucial to a comprehensive understanding of the labour market, in both developing and developed countries.

Data catalogue


In early 2021, the ILO Statistics Department started a three-year project to engender informality statistics, funded by the Bill & Melinda Gates Foundation. The project is running in parallel to the broader review of standards for informality statistics, currently undertaken through the ILO's Working Group on the Review of Informality Statistics. It supports integration of gender in the new standards, and the development of gender-related guidance and tools for measuring informality.

The main activity of the project is to test statistical concepts and household survey questionnaires, using cognitive interviewing in two countries in 2021 and a pilot field test in one country in 2022. The findings from those tests will support the working group in its discussions and drafting of the new standards, to be adopted by the 21st ICLS in 2023.

The project is also assessing the existing and anticipated needs for gender data on informality (data demand) and reviewing the use of data in strategy setting and policy formulation, making recommendations to strengthen the production, accessibility and use of gender statistics on informality.

Adopted in 1993 and 2003, the current statistical standards for measuring the informal economy need updating. They are out of sync with more recent international standards for measuring work. The 20th International Conference of Labour Statisticians (ICLS) established a working group in 2018 to develop a new conceptual framework for measuring informality (see para 124). The 21st ICLS in 2023 will discuss and adopt the new standards. A comprehensive set of tools and indicators will guide production, analysis and use of the data.

Coordinated by the ILO, the Working Group on the Review of Informality Statistics includes representatives from national statistical systems, international agencies and development partners. It meets annually with four subgroups established to support the work in between annual sessions.

Resolution concerning statistics on the informal economy

This resolution aims to set standards for statistics on the informal economy. It defines the statistical concepts of informal productive activities, the informal economy, the informal market economy and informal work and provides operational concepts, definitions and guidelines for the statistical measurement of its components.

Engendering informality statistics: gaps and opportunities

This working paper explores the demand for gender data on informality and the measurement challenges faced, and highlights the opportunities emerging from the revision of statistical standards on informality that are set to be adopted in 2023.

Measuring informality: A statistical manual on the informal sector and informal employment

This manual is intended for national statistical offices and other producers of statistics planning programmes to produce statistics on the informal sector and informal employment. The manual provides technical guidance on implementing international standards, presenting alternative measurement methodologies along with examples based on national experience, and includes guidelines for the dissemination of statistics on the informal sector and informal employment.

Measuring the non-observed economy. A handbook

The main focus of the Handbook is to provide guidance on how to produce exhaustive estimates of GDP. This means ensuring that as many productive activities as possible are observed, i.e., directly measured in the basic data on production, incomes, and expenditures from which the national accounts are compiled. It also means ensuring that non-observed activities are nevertheless accounted for, i.e., indirectly measured during compilation of the national accounts.

Resolution concerning statistics of employment in the informal sector

Adopted by the 15th ICLS (1993), this resolution provides technical guidelines as a basis for the development of suitable definitions and classifications of informal sector activities and the design of appropriate data collection methods and programmes, in the hopes such standards will enhance the international comparability of statistics.

Use the search box and filters above the table

Use the search box to enter key words; use quotes around your term for better results. Available filters differ depending on the catalogue. Selecting a frequency allows users to find monthly, quarterly, or annual indicators. While all indicators are available for annual periods, only a subset are available as monthly or quarterly. 

Options to access data

Data Explorer

This tool provides an intuitive interface to filter the selection, pivot the table, calculate distributions and growth rates, and export data into various formats.

Excel summary

Data available in the Excel summary files are for indicators only (not available for countries or regions) for selected classification items for 2010 onward for annual data and 2018 onward for short-term indicators. For historical data or additional classifications, either use the Data Explorer or download the CSV file. 

Country profiles

Available in the country catalogue only, this option takes users to the country profiles page with the selected country pre-filtered in the table. Highlighting the latest year available for key indicators, this is a subset of the available data for a given country.
