Informal employment is a major statistical concept in labour measurement. It should be distinguished carefully from the informal sector because a worker can have an informal job in different types of production units.
1. Informal sector and informal employment
The informal sector and informal employment are related but distinct concepts. The first refers to characteristics of production units under the relevant framework, while the second concerns the nature of the worker's employment relationship or job.
ISS questions on official statistics often test definitions, statistical units, denominators, rates, index concepts and interpretation of published data. Focus on the exact meaning of each indicator before applying a formula.
2. Why the distinction matters
A formal-sector enterprise can employ workers whose jobs have informal characteristics under a defined statistical framework. Therefore, informal employment cannot always be estimated simply by counting informal-sector enterprises.
Production-unit concept defined by the relevant statistical framework.
Employment relationship or job classified as informal under the stated definition.
Person engaged in economic activity under the survey's classification.
Population and jobs represented by the survey estimate.
3. Measurement through labour surveys
Household labour surveys can collect information on employment status, enterprise type, job characteristics, social security and related dimensions. The exact estimate depends on questionnaire design, classification and the reference period.
Always identify the numerator, denominator, reference period and unit before calculating an official-statistics indicator. In descriptive answers, define the measure first and then discuss uses and limitations.
4. Indicators of informal employment
Possible indicators include the share of workers without specified employment protections, social security coverage or formal written arrangements, depending on the adopted definition. Each indicator captures a particular dimension rather than the entire concept.
5. Statistical challenges
Multiple jobs, changing work arrangements, self-employment, platform work, unpaid family work and informal activities within formal enterprises create measurement challenges. Definitions must remain consistent while adapting to new forms of work.
7. Three important questions
Try each one on your own first, then tap the answer.
Why are informal sector and informal employment not identical?
Show answer
One describes characteristics of production units while the other describes the nature of employment or jobs.
A labour survey estimates 12 million informal workers among 30 million workers. Find the share of informal employment.
Show answer
12/30 × 100 = 40%.
Discuss challenges in measuring informal employment.
Show answer
Cover multiple jobs, self-employment, unpaid family work, informal jobs in formal enterprises, new work arrangements, classification and survey reference periods.
Key takeaways
- Informal sector and informal employment are distinct statistical concepts.
- Job characteristics matter in identifying informal employment.
- Labour surveys are important sources for employment structure.
- Changing work arrangements create continuing measurement challenges.
