A subnormal agglomerate is a form of irregular occupation of land – either public or private - owned by a third party, for housing purposes in urban areas, usually characterized by an irregular urban pattern, with scarce essential public services and located in areas not proper or allowed for housing use. In Brazil, those irregular settlements are known by the names of favelas, invaded areas, slums in deep valleys, slums in low-lands, communities, villages, slums in backwaters, irregular lots, shacks and stilt houses. As a major reference about the Brazilian population’s living conditions in all municipalities and intra-municipal subdivisions – districts, subdistricts, neighborhoods and localities -, the Population Census allows better identification of the subnormal agglomerates. So, it allows one to see their distribution throughout the country and to characterize services related to water supply, sewage disposal, garbage disposal and provision of electricity in those areas, thus presenting to society an update of the scenario of those areas of Brazilian cities that demand special public policies.
About the publication - 2010 - First results
The first results of the 6,329 territorial areas, classified as subnormal agglomerates in the 2010 Population Census show information about the resident population and the number of occupied households in favelas (slums), invasões (invaded properties), grotas (slums in deep valleys), baixadas (slums in low-lands), comunidades (poor communities), vilas (slums in villages), ressacas (slums in backwaters), mocambos (type of shack) and palafitas (stilt houses), among other irregular settlements for the Country, Major Regions, Federation Units and Municipalities.
The publication can be accessed in PDF format, including the methodological notes about the survey and the concepts and definitions of the features now released. The attached CD-ROM contains all the information available in the printed publication, including information for all the subnormal agglomerates surveyed and their limits in SHP or KMZ (compatible with Google Earth) formats, as well as selected social indicators.
Files for Google Earth
The Subnormal Agglomerates are presented, in this directory, in a format for Google Earth visualization. Each file represents a Federation Unit, where the material is organized according to the municipalities (in the first level) and their repective Subnormal Agglomerates (in the second level).
It is possible to identify in the file the name of the Subnormal Agglomerate, the number of occupied private households and the resident population in the occupied private households, according to the 2010 Population Census.
In this folder, the Subnormal Agglomerates are presented in two shapefiles:
AglomeradosSubnormais2010_Limites: File with the outline of the 6,329 Subnormal Agglomerates identified in the country in the 2010 Population Census. In the content table of these file you can find the code of the Subnormal Agglomerate (CodAGSN), the name of the Subnormal Agglomerate (NM_AGSN), the municipality code where the Subnormal Agglomerate is located (CD_GEOCODM), the municipality's name (NM_MUNICIP) and the Federation Unit code where the Subnormal Agglomerate is located (FU).
AglomeradosSubnormais2010_SetoresCensitarios: File with 15,868 classified enumeration areas which compose the Subnormal Agglomerates. In the content table of this file you can find the enumeration area code (CD_GEOCODI), the Subnormal Agglomerate code (CD_AGSN), the name of the Subnormal Agglomerate (NM_AGSN), the municipality code where the Subnormal Agglomerate is located (CD_GEOCODM), the municipality’s name (NM_MUNICIP) and the Federation Unit code where the Subnormal Agglomerate is located (FU).

What is a Subnormal Agglomerate?
A Subnormal Agglomerate is an irregular occupation of someone else’s property – private or public – for residential purposes in urban areas and, in general, are characterized by an irregular urban pattern, lack of essential public services and localization in areas restricted to occupation. In Brazil, those irregular settlements are known as favelas, squatting, grotto, lowlands, communities, villages, floodplain areas, mocambos, stilts, among others.
