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.
SUNFLOWER_H reports total harvested area dedicated to sunflowers, expressed in hectares, within a 10-kilometer buffer around each DHS cluster location. The harvested area statistics reported in SUNFLOWER_H are based on agricultural censuses and remotely sensed imagery circa 2000.
The related variable SUNFLOWER_P reports total crop production of sunflowers, expressed in metric tons and measured in the year 2000, within a 10-kilometer circular buffer around each DHS cluster location.
For some samples, some or all clusters have values of 0 only for the harvested area devoted to a particular crop. A value of zero indicates that the crop is not grown in this place, or is grown in too miniscule amounts to track, due to custom or unsuitable climatic conditions. For example, almost no area in Canada is devoted to growing pineapples.
SUNFLOWER_H, 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.
