The 21st ICLS

This International Conference of Labour Statisticians (ICLS), starting on 9 October 2023, will mark the 100th year of standard-setting in labour statistics since the first one took place in 1923.

What's on the agenda?

Informality | SDG indicators | Violence and harassment at work | the International Standard Classification of Occupations (ISCO) | International labour migration | Child labour | Forced labour | Cooperatives

How the standard-setting process works

The work of the ICLS is carried out based on ILO reports, one each for the main items and a general report for the others. The report on a subject contains proposals for a draft resolution, the first version of which typically would have been submitted to a Meeting of Experts for review and advice. Subsequent to the Meeting, the ILO continues its research and consultation activities to improve the draft proposals, taking into consideration the discussions and recommendations of the Meeting. Thus, the report prepared for the ICLS reflects detailed methodological research and analysis that are often of help to national statistical offices.

The reports are first briefly presented at a plenary session of the ICLS and then discussed in detail and amended, if necessary, by Committees that meet during the Conference. The resulting proposals from the Committees are then further debated at a plenary session before being adopted as amended (or rejected) by the Conference. The tradition is that decisions at the ICLS are taken on the basis of consensus with only occasional voting on particular points of a resolution. As much as possible, the standards adopted by the ICLS reflect “best practice” but they are not prescriptive, because of the differences that exist in statistical development, resources and infrastructure in the countries in which they are to be implemented.

About THE

International Conference of Labour Statisticians
(ICLS)

The ICLS is a vehicle for standard-setting in labour statistics, hosted by the ILO every five years

Activities

The ICLS makes recommendations on selected topics of labour statistics in the form of resolutions and guidelines, which are then approved by the Governing Body of the ILO before becoming part of the set of international standards on labour statistics. These standards usually relate to concepts, definitions, classifications and other methodological procedures which are agreed as representing ‘best practice’ in the respective areas. When used by national data producers (for example, national statistical offices), these will increase the likelihood of having internationally comparable labour statistics. 

Each ICLS provides a rare opportunity for labour statisticians throughout the world to meet each other and exchange views and experiences.

The Agenda

The ILO Governing Body decides on the agenda, following proposals by the Department of Statistics. Topics are identified based on recommendations of earlier ICLS sessions, the work of the Department, through other ILO programmes or signals received from users, national producers and regional and international organizations.

The main items on the agenda are those being considered for standard-setting. Meanwhile, other items are for discussion with a view to having guidance on the future work programme of the ILO, including future development, updating of standards or guidelines.

The most recurring topics are wages and hours of work (discussed at nearly all the ICLS), the classification of occupations, occupational injuries and unemployment.

Changes in the world of work and practices in official statistics, improvements in technology, methodological advances and new insights from experience make it necessary to revisit the same topics and review their existing standards over several ICLS sessions.

Experts in labour statistics from all over the world attend the ICLS. This includes most notably statisticians who work in national statistical offices, ministries of labour and selected representatives of workers’ and employers’ organizations.

No. In general, attendance must be self-funded.

No. Resolutions provide detailed guidance on conceptual frameworks, operational definitions and measurement methodologies to produce and disseminate labour statistics. Their purpose is to provide guidance to countries wishing to develop or revise their national labour statistics programmes, as well as to enhance international comparability. Guidelines provide more general guidance relating to particular areas of interest.

Almost 100 years of setting standards in labour statistics

1919
Statistics at the ILO
Embedded in the ILO Constitution

Since its inception in 1919, the ILO has been involved in statistical activities. Article 10.1 of the Constitution of the Organization requires "the collection and distribution of information on all subjects relating to the international adjustment of conditions of individual life and labour."

1921
Publication of statistics
Statistics on prices and unemployment first to be published

The ILO Bureau of Statistics began collecting labour statistics in the early 1920s with national figures of prices and unemployment, which were published in the International Labour Review as from its first issue in 1921.

1923
The ICLS is born
The Governing Body approves the convocation of a Conference of Statisticians engaged in the compilation of labour statistics

The purpose of the Conference was to consider the problems involved in the compilation of labour statistics and to agree, if possible, upon certain methods and standards with a view to rendering labour statistics more comparable across countries. 

The Governing Body debated the agenda of this first Conference at some length. The subjects finally chosen were:

  • Classification of Industries and Occupations;
  • Statistics of Wages and Hours of Labour;
  • Statistics of Industrial Accidents.

Thirty-three countries were represented, including almost every European State, and countries as far distant as Australia, Brazil, Canada, China, Japan, and India.

1924
ILO October Inquiry
ILO takes over survey to collect data on wages and food prices
Questionnaire dispatch, 2002

Since 1924, questionnaires have been sent out to ministries of labour or national statistical services to collect information for the October Inquiry and, since 1935, for the Year Book.

It was the First ICLS which recommended that the ILO should take over a survey, initiated a few years earlier by the British Ministry of Labour, to collect data on wages and food prices in 16 capital cities. Later known as the "ILO October Inquiry" because of its reference period, the survey was carried out from 1924 to 2010, providing a unique set of international wage and price data going back over 70 years.

1925
2nd ICLS

The Conference agenda included the classification of industries; cost-of-living index numbers; unemployment statistics; and international comparisons of real wages.

1935
ILO Year Book of Labour Statistics

Data on employment were soon added to the figures on prices and unemployment, and over the years the subjects covered gradually expanded to include wages, hours of work, industrial disputes and collective agreements. Time series on each of these topics were published in the Year Book of Labour Statistics, which was first issued in 1935.

Sources and methods
The introduction of technical guides

To provide users with information about the statistics it compiled and published, the Bureau launched a series of Technical Guides in 1964. These were issued every two years from 1968 to 1980, when a new, more detailed series of Sources and methods: Labour statistics was introduced. Preparing the methodological descriptions on the different subjects provided valuable insight into the methods used by countries, essential for the Bureau's developmental work for the international standards.
