IBGE publishes for the first time the geographic coordinates of the country’s addresses

-
  • Highlights

  • For the first time, IBGE publishes the geographic coordinates of all types of addresses in the country, collected during the 2022 Census and detailed by municipalities.
  • As of today, this data is available to the three spheres of government, as well as companies, NGOs and academic institutions. With these coordinates, government agencies can accurately count households exposed to the risk of flooding and landslides, while companies can refine their commercial strategies, for example.
  • The 2022 Census recorded 111.1 million coordinates, which locate various types (purposes of use) of addresses, of which 81.5% (or 90.6 million) are private households and 0.1% (or 104.5 thousand ) are collective homes.
  • The 2022 Census also recorded the coordinates of 11.7 million (or 10.5% of the total addresses) of establishments for other purposes (stores, banks, public buildings, shopping malls, among others), in addition to 264.4 thousand establishments for education, 247.5 thousand health establishments, 579.8 thousand religious establishments and 3.5 million buildings under construction or renovation.
  • The addresses visited are part of the National Register of Addresses for Statistical Purposes (CNEFE), used by IBGE in its household surveys, such as POF and PNAD Contínua.

IBGE released today (2) the geographic coordinates of the types of addresses in the 2022 Census. This is the first time that the Institute has captured this data for all households in the country. In the 2017 Agricultural Census, IBGE had already carried out this capture in rural areas, referring to agricultural establishments. During the 2022 census operation, these coordinates were used to monitor the work of the census takers and to monitor the progress of the collection. The publicity event, broadcast live, is being held at the Alcides Rufo State School, in Ponte Alta do Tocantins (TO).

The result of all this work will integrate the National Register of Addresses for Statistical Purposes (CNEFE), the address base used by IBGE not only in the Demographic Census, but also in other household surveys, such as the National Household Sample Survey (PNAD) Continuous, the Family Budget Survey (POF) and the National Demographic and Health Survey (PNDS).

From today onwards, microdata is available to society for application in various situations, such as locating addresses in risk areas, in the case of floods, landslides and fires. Another possible use is to locate addresses in public administration planning zones, in environmental conservation units and in areas where a specific enterprise operates.

Address coordinates can be used in conjunction with other databases, such as risk areas identified by the Mineral Resources Research Company (CPRM). “Through spatial filters, we are able to know how many private homes are within impact or susceptible areas, as well as establishments for other purposes, such as healthcare and buildings under construction too”, explains the manager of the IBGE Address Registry, Eduardo Baptist.

Geographic coordinates can be consulted by type of address. “We have the latitude, longitude and species code, that is, the purpose of using the address. This way, the user will know whether the point represented is a private or collective home, whether it is an agricultural, health or educational establishment”, explains Eduardo. Geographic coordinates can now be viewed on the Interactive Geographic Platform (PGI) and in the 2022 Census overview.

In the 2022 Census, 111.1 million geographic coordinates were recorded for the types of addresses identified in the census operation. Of this total, 109.9 million were validated after collection, which represents 98.9% of those originally from the Census registry.

The manager explains that each geographic coordinate refers to a type of address. “Each address has a coordinate. If there are two types of addresses in the same location, such as a private home and an agricultural establishment, then that same address will have two pairs of coordinates, with two different records in the product file.”

Of the total addresses collected in the Census, 81.5% (or 90.6 million) were private households and 104.5 thousand (or 0.1%) were collective households. It is also possible to observe the types of establishments in the country: most of them were used for other purposes, with 11.7 million (or 10.5% of the total). This group includes stores, for example. There were 264.4 thousand educational establishments, 247.5 thousand health establishments and 579.8 thousand religious establishments. In turn, there were 3.5 million buildings under construction. The distribution of these types of addresses among the federation units can be seen in the following table:

Digital collection of the Census allows the capture of geographic coordinates

The geographic coordinates of the addresses were collected by the more than 180 thousand census takers who worked on the 2022 Demographic Census, through their mobile collection devices (DMC). “These coordinates were collected during the confirmation or inclusion of addresses in the IBGE registry. The census taker, while traveling through the census sector, found the address on a previous list that was already loaded into the DMC. He confirmed those that already existed and were on the list and included those that were not. After including or confirming an address, the DMC application recorded the geographic coordinates of that unit visited”, says Eduardo.

He also tells how this collection of latitude and longitude in the field was used to supervise the work of the census taker. “During the interview, when the questionnaire was opened, the application automatically collected, in a transparent way, some geographic coordinates with a specific time interval, so that the supervisor could check whether the interview was carried out in the correct location”, adds the manager.

In CNEFE disclosures, data is only related to addresses, respecting statistical confidentiality. “The IBGE secrecy committee understood that the address data is not confidential. In this product, we are only disclosing the coordinates with the UF code and the municipality code, the maximum geographical area that IBGE has published so far”, he says. In the next release of CNEFE, scheduled for this year, other data will be included, such as the complete address, with street, number, complement, location and zip code.

More about the research

The Demographic Census is the most complete statistical operation carried out in the country, going to all households in the 5570 Brazilian municipalities and collecting the geographic coordinates of the types of addresses visited by census takers. The data can be viewed on the Interactive Geographic Platform (PGI) and in the 2022 Census overview.
