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.
GEO_ TZ1996_2015 reports the region of Tanzania where the respondent was interviewed. The variable is integrated to yield units with consistent boundaries across samples.
Labels identify the modern geographic units (regions) contained in each integrated region. Each sample also has its own non-integrated geography variable. The 2004, 2010, and 2015 samples have greater geographic detail available in their sample-specific variables. An additional integrated variable, GEO_TZ1991_2015, includes the 1991 Tanzania sample and has less geographic detail (zones).
