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.
SAMPLE 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 SAMPLESTR is a string variable that identifies the DHS sample with the same 4-digit code.
