Description
The Data: Coverage, Periodicity, and Timeliness

Coverage characteristics

 Disseminated data on population include annual projections and estimates by sex and age, in numbers of persons, covering the 1980-2050 period, for Brazil. The most important geographic subdivisions are the major regions, and states, in this case, for the 1991-2020 period. As Brazil takes a census every five years, population estimates and projections are updated, basically, with that same frequency. Population projections and estimates are based on data collected for Demographic Censuses, National Household Sample-Based Surveys, and Civil Register Vital Statistics for individuals. The most recent census was taken in 2000, the reference date of which is August 1. Estimates and projections for municipalities and metropolitan areas are based on growth trends observed in the last two censuses. In the context of the UNFPA/BRAZIL(BRA/98/PO8) project, the Population and Social Indicators Coordination of the IBGE’s Directorate of Research has already finished testing methodology for the near-term provision of municipal population projections by sex and age using the cohort ratio ("relação de coortes") method.

Periodicity

 Annual.

Timeliness

 Data on midyear population estimates are prepared within six months of conclusion of Demographic Census. Monthly population estimates for metropolitan areas are prepared by December, 31 of each year.
Access by the Public

Advance dissemination of release calendar

 An advance release calendar that gives one quarter ahead notice of the precise release dates is published on the website of the Central Bank of Brazil (http://www.bcb.gov.br/sddsi/calendar_i.htm) and on the IMF’s Data Dissemination Standards Bulletin Board (http://dsbb.imf.org).

Simultaneous release to all interested parties

 Data are made available to all interested parties in the Diário Oficial da União (DOU) "Official Gazette" on August 31 of each year, and also on the Internet at:
http://www.ibge.gov.br/pub/Estimativas_Projecoes_Populacao/
on October 31 of each year.
Integrity

Dissemination of terms and conditions under which official statistics are produced, including those relating to confidentiality of individual responses

 The following laws provide the legal foundation for the statistical functions of the IBGE:

  1. Law 5534 of November 14, 1968 (Law on the obligatory character of providing statistical data);

  2. Law 5878 of May 11, 1973 (Law of creation of IBGE);

  3. Law 6183 of December 11, 1974 (Law on Statistical and Geographical System);

  4. Decree 73.177 of November 20, 1973 that enacts these laws;

  5. Decree 74.084 of May 20, 1974 that approves the national statistical plan; and

  6. Decree 3.272 of December 3, 1999 that approves the organic law of the IBGE.

These laws establish the obligatory character of the provision of information to the IBGE and provide assurances of confidentiality of individual responses so that the data can be used only for statistical purposes. These laws are available to the public in Portuguese at the Internet page of the Presidency of the Republic, under search of decrees and laws:

http://www.planalto.gov.br.

According to these laws, dissemination of data by the IBGE is mandatory and free of charge.

In accordance with Law 59 of December 22, 1988, from 1989 onwards the IBGE has to produce annual estimates of the population of all municipalities in the country. Furthermore, Article 102 of Law 8443 of July 16, 1992, the IBGE has to publish populations estimates in the Diário Oficial da União by August 31 of each year.

Identification of internal government access to data before release

 No one has access to the information before it is released by the IBGE.

Identification of ministerial commentary on the occasion of statistical releases

 No comments by ministerial officials accompany the release of these data.

Provision of information about revision and advance notice of major changes in methodology

 Population estimates are considered final and official by the time of their release in the Brazilian Statistical Annual Survey. However, assumptions may be revised in light of new evidence concerning the behavior of the demographic variables.

Revised estimates and projections are disseminated in technical notes that are distributed through the CDDI (Centro de Documentação e Disseminação de Informações) and the SDDI (Serviços de Documentação e Disseminação de Informações). Data are also available to public on the Internet: http://www.ibge.gov.br.

Major methodological changes are published on the Internet: http://www.ibge.gov.br

Quality

Dissemination of documentation on methodology and sources used in preparing statistics

 The methodology used for population projections and estimates is disseminated by the IBGE, itself, in specific documents and at technical seminars.

Documents describing the methodology can be obtained through CDDI (Centro de Documentação e Disseminação de Informações) and the SDDI (Serviços de Documentação e Disseminação de Informações) and can be requested by e-mail (webmaster@ibge.gov.br).

Dissemination of component detail, reconcilliations with related data, and statistical frameworks that support statistical cross-checks and provide assurance of reasonableness

 The results of population projections and estimates for the entire country, states, and municipalities are published by gender and age. These data are widely used to evaluate the extent of school enrollment (Ministry of Education), vaccination campaigns (Ministry of Health), number of voters in election years (Superior Electoral Tribunal), and also serve as reference parameters for evaluating information on doctors’ visits and hospitalizations in the Unified Health System (SUS) of the Ministry of Health.

Summary Methodology
Analytical framework, concepts, definitions, and classifications (including reference to applicable guidelines)

The Population and Social Indicators Coordination of the Directory of Research at the IBGE is currently implementing an Integrated System of Population Projections and Estimates and Sociodemographic Indicators, a project supported financially by the United Nations Fund for Population Activities (UNFPA). The purpose of the Integrated System is to provide population projections by sex and age for the entire country, covering the 1980-2050 period. For its five major regions, the 26 states and the Federal District the period is 1991-2020. The demographic components method is the methodology used in according of the recommendations of the United Nations Population Division. Patterns of fertility, mortality and migration (internal and international) are projected. The projected parameters are applied to the respective base populations (resident population according to the initial population given by the 1980 or 1991 Demographic Censuses, depending on the case, adjusted on a semi-annual basis with minimal census undercount corrections).

In the year of 2007 the resident population of Brazil is the result of the sum of the municipal population that were object of the counting procedure and of those municipalities that had its population estimated, according to the established criteria for the 2007 Population Counting. For 2007, the reference date is April 1st, 2007, while the estimate for the previous year is referred to July 1st, 2006.
Scope of the data (coverage of, e.g., institutional units, transactions and stock, commodities, industries, and geographic areas)
Data on resident population—levels: national, regional, state, and municipal.
Accounting conventions (e.g. time of recording, valuation methods)
 
Nature of the basic data (e.g., administrative records, surveys censuses, combinations of these)
Basic data from Demographic Censuses, National Household Sample Surveys (PNADs) and Civil Register Vital Statistics.
Compilation practices (e.g., weighting schemes, imputation methods, balancing/cross-checking techniques)
Not applicable.
Other aspects (e.g., seasonal adjustment, disclosure avoidance, base years, reference years, transformations from fiscal to calendar years)
The reference date for annual population projections and estimates is July 1 of each year. For the expansion of the Monthly Employment Survey carried out in Brazilian metropolitan areas, the monthly estimates relate to the fifteenth of each month. The pop-clock on the IBGE homepage provides population estimates for the country as a whole every minute.
