2. National Economic Surveys (NES) • Introduction • An integrated system of surveys • Benefits • Other economic surveys • Data dissemination • Conclusions X

3. Introduction Mexico’s size • Territory of 2 millions square kilometers. • Population of 103 millions inhabitants. • 3 millions establishments counted by economic censuses. • GDP: commerce and services 70%, industry 26% and primary sector 4%.

4. Introduction • 32 state offices: collection and data entry to the system. INEGI’s structure • 10 regional offices: coordination, supervision and link INEGI to informants as well as to the state and municipality authorities of the region. • Central office in the city of Aguascalientes: gives norms and methodological proce-dures; disseminates the information.

5. Introduction Economic surveys’ background Annual and Monthly Continuous Surveys in Establishments • Manufacturing Survey (1963). • Survey on Building Firms (1983). • Survey on Commercial Establishments (1983). • Monthly Survey on Management Opinion (manufacturing) (2007). • Survey on Services (non financial private services and the transporting sector) (2007).

6. Introduction Economic surveys’ background • Different conceptual frames and questionnaires among surveys. • Some overlaps in information requests between the economic censuses, themonthly and annual surveys. • Teams of work were duplicated among surveys. • Irregular load assignment among interviewers.

7. Introduction Economic surveys’ background • Inefficient use of time, caused by long distances between establishments or firms developing in the same economic sector. • People for collecting and other to entry data into computers. • Difficult to obtain productivity indicators. • If the firm was involved in different sectors (manufacturing, commerce and services), several interviews.

8. National Economic Surveys (NES) • Introduction • An integrated system of surveys • Benefits • Other economic surveys • Data dissemination • Conclusions X

9. An integrated surveys’ system General objective of National Economic Surveys (NES) • Provide useful, high-quality and timely primary statistics, through continuous surveys, integrated to economic censuses and administrative registers in order to: • Satisfy national and international needs of statistical information. • Satisfy national accounts requirements. A multidisciplinary group elaborated the scheme of all surveys.

10. An integrated surveys’ system Specific objectives of National Economic Surveys (NES) • Integrate NES to economic censuses. • Common methodological criteria among surveys. • Consideration on historical comparisons. • Provide useful information to national accounts compiling. • Permanent NES modernization. • Observe international standards for the collection and dissemination of statistics.

11. An integrated surveys’ system • The major changes took place in: • Conceptual and sample frame • Data collecting and analysis

12. Reengineering towards an integrated surveys system Conceptual frame One area in charge of conceptual design for surveys, economic censuses and administrative registers. • Assure conceptual and nomenclature homologation. • Apply standardized concepts in surveys according to SNA 1993. • Homogeneous measurement of production among activities in manufacturing (transformation and in-ward processing). • The North American Industrial Classification System (NAICS) in surveys and economic censuses.

13. Common variables: occupied personnel, wages and salaries, income and expenditure, worked days and fixed capital. Specific variables: For example, volume and value of products in manufacturing, transported passengers in the transporting sector, works carried out in construction, and clients and suppliers in commerce. Reengineering towards an integrated surveys system Conceptual frame • Questionnaires with a common part and other with specific variables.

14. Reengineering towards an integrated surveys system Conceptual frame • No repetitive information requirements among monthly surveys, annual surveys and economic censuses. • A unique instructive for the questionnaire filling. • Design of a unique automatic validation criteria for all surveys. • Interviewers’ training: real time and long distance courses. • Preparation of instruments and documents that facilitated the performance of all the parties involved.

15. Reengineering towards an integrated surveys system Sample Frame Substitution of the old frame for that provided by 2003 economic censuses.

16. An integrated surveys’ system • Conceptual and sample frame • Data collecting and analysis

17. Reengineering towards an integrated surveys system Data Collecting • It was created the figure of “the universal interviewer”. • In the case of firms involved in several sectors,just one interviewer collects the information in a single visit. • Interviewers also entry the data into the computers. • Generation of reports on the performance of all operative personnel. • Homologation of wages among interviewers.

18. Reengineering towards an integrated surveys system Data collecting • One team supervises coverage advances. • Implementation of internet collecting: mainly in large firms. Data treatment and analysis • Personnel were reallocated setting up a group of experts in sectors dedicated to the treatment and analysis of data.

19. National Economic Surveys (NES) • Introduction • An integrated system of surveys • Benefits • Other economic surveys • Data dissemination • Conclusions X

20. Benefits Immediate Benefits • Greater control on interviewer performance. • Optimization of resources and time. • A knowledge increase of interviewers on the sectors involved. • People in the central office got specialized in conceptual design, operative strategy or treatment and analysis. • It was a reduction of informants’ load. • An incorporation of new technologies in processes.

21. National Economic Surveys (NES) • Introduction • An integrated system of surveys • Benefits • Other economic surveys • Data dissemination • Conclusions X

22. Other economic surveys (in households) • National Occupation and Employment Survey (monthly and quarterly): Typology of labor markets under the SNA Institutional Sector framework. • National Survey on Consumer Confidence (monthly). • National Household Income and Expenditures Survey (biannual).

23. National Economic Surveys (NES) • Introduction • An integrated system of surveys • Benefits • Other economic surveys • Data dissemination • Conclusions X

24. Data dissemination • Monthly and quarterly data are disseminated through a year-advance release calendar. • Currently working in a calendar for annual surveys and national accounts information. • Metadatas and methodologies are posted on INEGI’s and IMF DSBB´s websites. • Press bulletins, electronic publications, hard copies, CD´s, data bases and on-line systems. • IMF standards are observed.

25. National Economic Surveys (NES) • Introduction • An integrated system of surveys • Benefits • Other economic surveys • Data dissemination • Conclusions X

26. Conclusions • National Economic Surveys are now an integrated system, coordinated, consistent and continuous, yielding: • Comparable statistical information, obtained more efficiently. • Reduction of time and costs for both informants and INEGI. • A greater advantage for national accounts compilers. • An easier interpretation by users and analysis of data.
