  5. Summary of the deliberations and recommendations 


    The first session of the meeting was devoted to presentation of case studies on the operationalisation of the concept of Informal Employment as distinct from Informal Sector Employment. The following papers were presented in the session:

    1. A labour   force survey module on informal employment, (including employment in the   informal sector) as a tool for enhancing the international comparability of data   (Part-I)- Ralf Hussmanns, ILO 
    2. Testing   the conceptual frame work of informal employment - A case study of India - Dr.   G. Raveendran, India
    3. The   concepts of informal sector and informal employment,: An application for   Brazil - Angela Filgueiras Jorge  and   Lucilia Valadao, IBGE
    4. Analysis   linking data on work in informal employment and poverty: Case study of India   -Dr. N.S. Sastry, WIEGO 
    5. Operationalisation   from the point of view of the policy maker - Lourdes Ferran,   Venezuela. 

    The session started with a brief presentation of the conceptual framework of informal employment, which is a broader concept than employment in the informal sector, by Ralf Hussmanns, ILO. He mentioned that an international statistical definition of informal employment is yet not available though informal employment exists in different forms like unregulated employment, unprotected employment precarious employment, etc. In order to arrive at such a definition, the approach suggested by the ILO for defining informal employment needs to be tested and evolved on the basis of country experiences and methodological studies. He announced that the 17th International Conference of Labour Statisticians, to be held in Geneva in November/December 2003, would discuss the issue of measuring informal employment. 

    The paper by A. Filgueiras Jorge and Lucilia Valadao of Brazil presented experiences of Brazil in constructing the ILO conceptual framework of informal employment. It was concluded that it was possible to estimate the informal employment generated in the Brazilian economy through the exercise. The paper by Rodrigo Negrete, Mexico was presented by Ralf Hussmanns as Mr.Rodrigo could not attend the meeting. In his paper, Mr. Rodrigo has argued that in Mexico agriculture needs to be treated separately for the measurement of both employment in the informal sector and informal employment. He has also mentioned that specialized surveys would not be needed for the estimation of informal employment with some modifications in the labour force surveys questionnaires, it would be possible to construct the ILO framework of informal employment though quality issues need to be addressed. He has also suggested that use of the term informal employment in parallel with ‘informal sector employment’ is likely to create confusion and that therefore, it would be preferable to change ‘informal employment’ to non-protected employment. 

    The paper by Dr. G. Raveendran, India presented the distribution of employment over formal and informal in the conceptual framework of the ILO based on the labour force survey conducted in India during July 1999 to June 2000. The paper concluded that it would be possible to estimate the magnitude of informal employment through labour force surveys by a suitable modification of the survey schedules. It would be, however, difficult to identify the single-most distinctive feature of informal employment in each country. Thus a fully harmonized definition of informal employment may not be possible in the present context.


    The paper from the National Council of Applied Economic Research, India was presented by Dr. G. Raveendran in the absence of any representative from the Council. The paper covered four case studies undertaken by the Council to identify informal employment. The case studies have brought out interesting results about women’s work force. However, the studies are not according to any framework or statistical procedures.

    The Group recognized the need for consolidating the country experiences and undertaking further research for evolving a statistical definition of informal employment and methods of compiling informal employment statistics through labour force surveys.



    The second session was devoted to ‘Linkages of Informal Sector Statistics with Income and Expenditure and Poverty Statistics. The following papers were presented:

    1. Analysis of linking data on work in   informal employment and poverty: Case study    of India - Dr. N.S. Sastry, WIEGO 
    2. Operationalisation   from the point of view of the policy maker Lourdes Ferran, Venezuela 
    3. Rethinking   informal economy in Rio de Janeiro slums    - Denise Britz do Nascimento Silva, IBGE, Brazil 


    The linkage between employment in informal sector, poverty and gender in the case of India was analysed in the paper by Dr. N.S. Sastry by making use of the unit level data relating to the Labour Force Survey conducted by the National Sample Survey Organisation (NSSO) of India during July 1999 to June 2000. At the first instance, a sub-set of households defined as "households sustaining on employment in informal sector" was identified by using the criterion that at least one usual principal status worker of the household is in the informal sector and no usual principal status worker outside the informal sector. 

    The linkages of these households and some of their further sub-sets to poverty were analysed by using the data available on consumption expenditure on an abridged format after making adjustments for under-estimation. The important findings were:


    1. The   poverty situation of households sustaining on employment in informal sector   was worse in the urban sector than in the rural sector, whereas in the entire   population, it was in the reverse order both in the case of urban and rural   sectors.  
    2. In rural   India, as compared to the entire population, lower levels of poverty were   observed among the persons belonging to households which sustained on (a)   employment in informal sector, (b) self-employment in informal sector,   (c) employment in informal sector and were headed by females, and (d) employment   in informal sector with only one male usual principal status worker. However,   higher poverty levels were observed amongst the households which sustained on   (a) employment in informal sector with either only a female usual principal   status worker or with one male and one female usual principal status worker, (b)   employment in informal sector with no literate member and,  (c) employment in informal sector with no   literate female member. 
    3. In   urban India, compared to the poverty estimate in the general population, poverty   was at nearly the same or lower levels among persons belonging to households   which sustained on (a) self employment in informal sector, (b) regular   salary/wage employment in informal sector, and (c) employment in informal sector   with only one male usual principal status worker. The incidence of poverty in   the case of all other categories of households sustaining on employment in   informal sector was higher as compared to the general   population.


    The group appreciated the study and suggested that further research should be carried out to identify the causes of variations in the poverty situation of urban and rural households sustaining on employment in informal sector, its inter-relationship with competition from the formal sector, capital endowment and technology adoption, the relevance of the sector as a poverty alleviation strategy and above all the policy implications of the findings. It was also suggested to study the poverty situation of households with different members pursuing different informal sector activities as against those households with all the workers pursing the same informal sector activity. 

    The paper by Lourdes Ferran on "Operationalisation from the point of view of the policy-maker "provided a critical assessment of the existing statistics, concepts and classifications on informal sector in relation to the requirements of policy-makers. She mentioned that the problems of informal workers are problems caused by poverty and, therefore, the statistics of the sector should bring out a clear picture of the sector, in order to be able to provide measures for the improvement of social security issues like health policies, development policies like absorption of underemployed persons into formal activities, trade union policies, welfare and occupational policies, etc. It was, therefore, argued that statistical activities relating to informal sector should be more oriented towards these directions.

    It was pointed out during the discussions that there can be both policy-related statistical activities as well as policies based on statistical findings, and that statistics relating to any sector can have dimensions of environment, social aspects and economic impacts.

    The third paper on "Rethinking informal economy in Rio de Janeiro slums" by Denise Britz do Nascimento Silva presented the dimensions of the informal sector in 51 slums of Rio de Janeiro. The Group noted the results of the study with interest.


    SESSION III:The topic "Establishment of Comparable Data sets on Informal Sector" was discussed in the third session and the following papers were presented.

    1. Preservation   of macro-data at the national level: case study of India- Dr. N.S.Sastry,   WIEGO. 
    2. A labour   force survey module on informal employment, (including employment in the   informal sector) as a tool for enhancing the international comparability of data   (Part II) - Ralf Hussmanns and Brigitte du    Jeu, ILO.
    3. Project   proposals received from some of the countries (presented by Dr. G. Raveendran,   India).


    The paper by Dr. Sastry was in the context of the recommendation by the fifth meeting of the Delhi Group for the establishment of a common pool of databases on informal sector and the decisions by a WIEGO planning meeting organized at Geneva during June 2002. The paper provided a vivid picture of various sources of data in India like the economic census, follow-up enterprise surveys, household surveys of un-organised units, survey of small scale industries, labour force and informal sector surveys and the manner in which unit level data sets are being made available for research purposes at nominal cost. The paper stressed the importance of preservation, harmonization and synergisation of micro-data for policy formulation as well as for developing countries to replicate the efforts so that comparable data sets on the informal economy could be established. It was clarified during discussions that in India, the identity of the individual units providing data could be suppressed by removing the identification particulars. 

    The paper by Mr.Hussmanns dwelled on the problems of lack of comparability of data collected from national sources due to various reasons including differences in definition, coverage, methods of data collection, etc. He also mentioned the data sets being maintained by the ILO on informal sector employment and their limitations including the fact that no data sets are available in respect of China. A compendium of official statistics on employment in the informal sector prepared by the ILO based on the statistics made available by the countries was distributed during the meeting. Ms. du Jeu presented an analysis of the data published in the compendium. 

    Mr. Hussmanns described the numerous factors which are responsible for the lack of comparability of data. He mentioned that even in instances, where the international definition was followed, the flexibility in the definition may lead to non-comparability of data sets. He also mentioned the limitations of labour force surveys arising out of short reference periods leading to non- capturing of seasonal variations and the difficulty in estimating the number of informal sector enterprises. He outlined various ways for enhancing the data comparability by harmonizing macro or micro data sets.


    Harmonisation of macro data could be done through reprocessing of existing data as well as by making model-based adjustments. Micro level data harmonizing can be achieved by collecting data according to a uniform list of items by each country. To this end, he proposed a standard module of questions to be included in labour force surveys for the identification and estimation of employment in the informal sector and informal employment.

    During the discussions concerns were expressed about the applicability of the different questions included in the proposed module in different countries. It was however clarified that the questions and their response categories were meant to be merely indicative of the kind of information needed to identify employment in the informal sector and informal employment, and that their exact wording would have to be determined by each country itself. It was suggested that additional case studies should be conducted in selected countries on a regional basis before any such module can be recommended by the Group.

    The last presentation by Dr. G.Raveendran was a summary of responses received from the State Statistical Committee of Azerbaijan Republic, Central Statistical Authority of Ethiopia, Statistical Centre of Iran, Central Statistical Office of Mauritius and National Statistical Office of Thailand in response to a communication sent to all the countries interested in the Delhi Group.

    Azerbaijans proposal suggested confirmation of definitions and coverage, summarizing of observations and estimation and the need to conduct a training course to improve questionnaires for the survey. Ethiopias proposal was to conduct an "Urban Informal Sector Survey" during July 2002 to August 2003. Iran suggested to take advantage of the experiences of developed countries and proposed data collection through income-expenditure and time use surveys. Mauritius proposal is restricted to data collection from censuses and surveys of household and establishments, since they do not have a defined informal sector.

    Thailand proposed to undertake studies by selected countries to improve the quality of existing data and to document country experiences as had been suggested by the ILO in previous meetings of the Delhi Group. Thailand also suggested workshops and visits to participating countries

    On the basis of the papers presented and the discussions thereafter, the Group reiterated the need for having comparable data sets on the informal sector and their proper archival for use by all interested agencies.


    ‘Methods and procedures for the collection of informal sector statistics on a regular basis including preparation of a manual’ was the fourth session and the following papers were presented.

    1. Improved   statistics on the informal economy - user needs - Martha Chen, Margarita   Guerrero and Joann Vanek, WIEGO
    2. A   review of national surveys and possible contents of a manual on informal sector   statistics - Dr. G. Raveendran, India.

    The first paper proposed four items for further work to improve statistics on the informal economy viz. (a) concepts and methods to improve data collection; (b) preparation of global and regional estimates of the size and contribution of the informal economy; (c) policy -oriented research reports; and (d) data archive for national data on the informal economy. The presenter also raised the issue of what could be done to strengthen the Delhi Group, especially with a view to increasing the participation of countries in its meetings. The Delhi Group took note of the proposal, which would be taken into consideration while determining the future work programme of the Group. Regarding the participation of countries in the Delhi Group meetings, lack of funding to attend the meetings and use of a single working language (English) were identified as the major obstacles to increasing the country participation during the meetings. It was agreed that efforts should be made to obtain donor funding for future meetings of the Group, including funds for interpretation to Russian, Spanish and French. The translation of the papers prepared for the meetings was considered to be of lesser importance. It was recalled that participation in the Delhi Group was open to all countries, irrespective of their level of development, but that issues of employment statistics, which were not directly related to the informal economy, were to be dealt with by the Paris Group.

    The second paper presented a proposal for the preparation of a comprehensive manual for the collection of internationally comparable informal sector statistics. It was also argued in the paper that efforts should be made to also measure informal economy through income and expenditure surveys. During the discussion of the paper, a view was expressed that the proposal was too ambitious and did not mention how the work could be organised to prepare the manual. The meeting was informed that in 2002 the OECD, IMF, ILO and Statistical Committee of the Commonwealth of Independent States had already published jointly a handbook on Measuring the non-observed economy, which dealt with the national accounting aspects of the subject in sufficient detail and was available in English, Russian and French. The meeting was also informed that the ILO had already started preparation of a methodological manual on informal sector surveys. Once a complete draft of the manual was available, the Delhi Group would be invited to devote one of its future meetings (perhaps the meeting in 2004) to a discussion of the draft. The ILO offered to host that meeting in Geneva.


    Session V was devoted to discuss the future programme of work of the Delhi Group. The consensus in the meeting was to focus on the following:

    1. The future work of the Delhi Group needs to be   enlarged to develop methodologies for addressing policy issues while continuing   to focus on developing high quality informal sector statistics.
    2. To ensure participation of more countries, the   assistance of funding agencies should be sought for assisting countries, which   have already undertaken informal sector surveys, to undertake evaluations of the   data quality and present the results in the next meetings of the Delhi   Group.
    3. Further studies should be undertaken regarding the   collection of data on status in employment and precarious employment, which are   closely related to the measurement of employment in the informal sector and of   informal employment.  (Comment: This   point was made by Argentina and accepted by the   others.)
    4. The next meeting should focus on issues like national   accounts, poverty and policy implications of the informal   sector.
    5. The ILO will host the 2004 meeting of the Delhi Group   at Geneva, if a complete draft of its manual on informal sector surveys is ready   by then. In the meantime, the Delhi Group should examine the OECD/IMF/ILO/CIS   handbook on measurement of the non-observed economy, which deals with the   national accounts perspective and includes a chapter on the informal   sector.




    1. The   Group recognized the need for consolidating the country experiences and   recommended further research for evolving a statistical definition of informal   employment and methods of compiling informal employment statistics through   labour force surveys.  
    2. It was   recommended that the countries undertaking combined labour force and expenditure   surveys may undertake further research to evolve methodologies for linking   poverty estimates and informal sector employment.  
    3. The   Group recommended a joint meeting of the Rio Group and the Delhi Group for   addressing the issues relating to the linkage between informal sector and   poverty .  
    4. The   Group recommended that countries need to be encouraged to develop comparable   data sets on the informal sector and properly archive them for use by all   interested agencies.
    5. The   countries undertaking income and expenditure surveys need to be encouraged to   identify methods for measurement of the informal economy through such   surveys.  
    6. It is   recommended that the ILO should complete a methodological manual on informal   sector surveys and present its draft for discussion by the Delhi Group, if   possible during the meeting in 2004.  
    7. To   ensure participation of more countries in the Delhi Group, the Chair and members   of the Group should approach donor agencies to obtain funding for its meetings,   including funds for interpretation.   
    8. The   future work of the Delhi Group needs to be enlarged to develop methodologies for   addressing policy issues like poverty while continuing to focus on developing   high quality informal sector statistics. The necessary base papers for the next   meeting need to be prepared in advance and circulated for the countries to   prepare research papers.  
    9. Countries   should be encouraged  (e.g. through   financial support provided by donor agencies) to undertake an evaluation of the   quality of their informal sector statistics and to present the results of such   studies in the next meetings of the Delhi Group.
