Territory of 2 millions

square kilometers.

Introduction

Mexico’s size

Population of 103

millions inhabitants.

3 millions establishments

counted by economic

censuses.

GDP: commerce and

services 70%, industry

26% and primary

sector 4%.

32 state offices: collection

and data entry to the system.

Introduction

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.

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).

Introduction

Economic surveys’ background

Annual and Monthly Continuous Surveys in Establishments

Introduction

Different conceptual frames and questionnaires among surveys.

Some overlaps in information requests between the economic

censuses, the monthly and annual surveys.

Teams of work were duplicated among surveys.

Irregular load assignment among interviewers.

Economic surveys’ background

Introduction

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.

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.

General objective of National Economic Surveys (NES)

An integrated surveys’ system

A multidisciplinary group elaborated the scheme of all surveys.

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.

Specific objectives of National Economic Surveys (NES)

An integrated surveys’ system

The major changes took place in:

Conceptual and sample frame

Data collecting and analysis

An integrated surveys’ system

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.

Conceptual frame

Reengineering towards an integrated surveys system

One area in charge of conceptual design for surveys, economic

censuses and administrative registers.

• 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.

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.

Reengineering towards an integrated surveys system

Sample Frame

Substitution of the old frame for that provided by 2003 economic censuses.

Conceptual and sample frame

Data collecting and analysis

An integrated surveys’ system

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.

Data Collecting

Reengineering towards an integrated surveys system

One team supervises coverage advances.

Implementation of internet collecting: mainly in large firms.

Data collecting

Reengineering towards an integrated surveys system

Personnel were reallocated setting up a group of experts in sectors

dedicated to the treatment and analysis of data.

Data treatment and analysis

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.

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.

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.

Conclusions

• Thank you.
