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.
MALARIA consists of a set of 16 separate variables, covering each year from 2000 to 2015. The variables report, by year, the mean clinical Plasmodium falciparium malaria cases (across all ages) per person within a 10-kilometer circular buffer around each DHS cluster location. Alternatively, this statistic can be summarized as the mean clinical plasmodium falciparum prevalence (PfPR), expressed as fractions of a case per person. MALARIA is available for a subset of the IPUMS-DHS samples with GPS data; see Comparability.
By adding MALARIA to your data cart, you are in effect adding 16 separate variables (MALARIA_2000 to MALARIA_2015), one variable for each year.
MALARIA, like the other IPUMS-DHS contextual variables, is calculated and based on sources external to the DHS data. For more information on IPUMS-DHS contextual variables and how they are constructed, refer to the documentation [URL omitted from DDI.] on these variables.
