Project for the Reformulation of IBGE's Household Sample Surveys

Project for the Reformulation of IBGE's Household Sample Surveys

The growing demand for socioeconomic and demographic information has become a reality for Official Statistical Agencies all over the world, characterizing an enormous challenge, due to the limited availability of resources.

The expansion of this information system is expected to encompass new topics and a deeper analysis of topics already treated, allowing surveys to be conducted at shorter or more regular intervals.

A possible solution to promote the adaptation of statistical agencies to this new reality has been the use of system-models with integrated production of data sources and databases.

Methodology and coverage reformulation of the main IBGE household surveys, such as the National Household Sample Survey PNAD), Monthly Employment Survey (PME), Consumer Expenditure Survey (POF) and Survey of Urban Informal Economy (ECINF) have always occurred individually. However, for the last few years, IBGE has developed the Integrated System of Household Surveys (SIPD), in which each topic investigated will be part of an integrated system of economic and demographic indicators. Planning, execution, dissemination and analysis of results of several surveys will be treated together, thus optimizing the use of resources and making it easier to meet new demands.

The model proposed by IBGE encompasses:

  • adoption of shared selection records and sample design, aiming at the optimized production of statistical information based on household surveys;
  • harmonization of concepts, variables and classifications in the several investigations of SIPD components, so as to facilitate the comparative analysis of results;
  • harmonization of the processes of editing, imputation, tabulation, whenever indicated;
  • bigger use of technology for obtaining data, also including the decision-making process concerning the most appropriate technology (PDA, Notebook, Computer-assisted telephone system);
  • development of adequate conditions for the implementation of longitudinal studies;
  • production of national short-term indicators on labor and income detailed by Federation Unit;
  • production of continuous information about consumption, aiming, principally, at the conduction of studies on Life Conditions, update of data relative to poverty measure, national accounts and inflation;
  • flexibility for the inclusion of new topics such as Victimization, Time Use;
  • detailing of topics already investigated, such as: Food Security, Access to Income Transfers from Social and Health Programs, Child Labor;
  • regularity in the investigation of topics such as: Food Security, Access to Income Transfers from Social and Health Programs, Child Labor;

The thematic core of this system Will be formed by Continuous PNAD, a survey which will integrate PNAD and PME, and the group of Continuous POFs, formed by the complete edition of POF, conducted every 5 years, and the simplified POF, which will be conducted continuously. Once these surveys are continuous and serve several purposes, will naturally lead to supplementary investigation.

SIPD planning requires close contact between users and producers of information. In this respect, the concluded steps of SIPD have been presented in seminars and congresses promoted by IBGE or other institutions.

Users are certainly entitled to the monitoring and evaluation of paths taken towards the conclusion of this new Project.

II National Meeting of Producers and Users of Social, Economic and Territorial Information (CONFEST/CONFEGE) - August 2006

In this event, the SIPD Project was the subject of several discussions approaching sample aspects proposed for the new survey system and the thematic lines relative to conjuncture indicators about labor. Project development, both in operational and thematic aspects, had the participation of specialists in the use household sample surveys microdata, of representatives of the Ministry of Employment and of the Ministry of Social Development and Combat to Hunger, besides a consultant from the International Labor Organization.
