SAMPLESTR is a string variable that identifies the DHS sample from which the case is drawn. Each sample receives a unique 4-digit code. The first three digits are ISO/UN codes used in COUNTRY, and the last digit identifies the sample within the country, ordered by survey year.
The related variable SAMPLE is a numeric variable that identifies the DHS sample with the same 4-digit code.
