BARLEY_P reports the total crop production of barley, expressed in metric tons, within a 10-kilometer circular buffer around each DHS cluster location. The crop production statistics reported in BARLEY_P are based on agricultural censuses and remotely sensed imagery circa 2000.
The related variable BARLEY_H reports the total harvested area dedicated to barley, expressed in hectares, within a 10-kilmeter buffer around each DHS cluster location, as measured in the year 2000.
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.
BARLEY_P, 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.
