Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
SOIL reports the predominant soil type within a 5 kilometer circular buffer around each DHS cluster location. The soil attributes reported in SOIL are: soil class (e.g., Leptosols) and soil type within that class (e.g., Lithic Leptosols). SOIL is available for every IPUMS-DHS sample with GPS data.
There are 118 different soil types in the world. Please see the User Note on Using IPUMS-DHS Contextual Variables: Soil [URL omitted from DDI.] or the list of soils and the 4-digit codes [URL omitted from DDI.] (e.g., 1703) consisting of the 2-digit soil class code followed by the 2-digit soil type code. The User note also describes the data source and methodology used to calculate this variable. This variable, like the other IPUMS-DHS contextual variables, is based on sources outside The DHS Program, with values around DHS sample cluster points calculated by IPUMS-DHS staff.
