Dwelling fractions for Colombia

Colombia is divided into 32 departments plus Bogota (the country's capital) and 1114 municipalities. An exposure model has been developed in terms of the number of buildings as well as economic value (replacement cost of the structures, excluding contents and non-structural components) at department, province and district level.

Information about building characteristics was based on data from census 2005, DANE (Departamento Administrativo Nacional de Estadística, Colombia).

In order to improve the understanding of the typical and common building types in the region, the results coming from PAGER and UN-HABITAT and the ones coming from the GEM Workshop in Medellin are summarized in the following figures. In addition, a summary of the housing reports coming from the World Housing Encyclopedia (WHE) are presented.

A summary of information provided in the census 2005 at national level is presented in the following pie charts. These results show dwelling fractions according to the predominant exterior wall material (“material de paredes exteriores”), floor material (“material del piso”), dwelling type (“tipo de vivienda”) and type of area (“tipo de area”); and also pie charts have been generated for dwelling fractions in urban and rural areas (pie charts on the top and bottom respectively) according to the type of house and the material of the floor.

Using the previous information and expert judgement, a mapping scheme to classify the dwellings into a set of building typologies has been developed (see figure). Despite having several features for classifying the building portfolio, the web applications for downloading census data only allows disaggregation of the number of dwellings in each region by a maximum of two attributes. Therefore, the updated schemes were based on the material of the exterior walls and the material of the floor.

The mapping scheme consists on a table that allocates a building category according to the material of the exterior walls and the material of the floor. The building typologies have been defined in accordance with the GEM Building Taxonomy.

Regarding the census attribute definitions, concrete exterior walls has been assumed to represent confined masonry walls, infill reinforced concrete frames or precast concrete walls (with low construction quality), and the type of house Covacha refers to an informal construction generally characterised by wooden exterior walls.

Colombia has a total number of dwellings of 9,742,956 distributed across 28 building typologies (taxonomy categories) (see Table 2.1). Figure 2.11 illustrates the proportion of dwellings in each taxonomy category at a national level and the proportions for the municipality of Cali (located in Valle del Cauca department) and the department of Guainia. At a national level the predominant categories in terms of predominant construction material are Unreinforced and confined Masonry (41% and 19%, respectively), whereas at department and municipality levels the proportions vary considerably. For example, in Cali the percentage of dwellings in the Wood category is just 5% while in the department of Guainia this percentage goes up to 42%.

Dwelling distribution along Colombia is shown in the following maps using different resolution levels. At the Department level 1(a), pie charts show the proportion of each building typology in the region. The pie charts are not shown in the other figures for the sake of clarity.
