The data tables incorporate data from the household surveys mentioned above. We also used the Demographic and Health Surveys (DHS) for supplemental health information for each respective country. DHS data can be downloaded at http://www.measuredhs.com/accesssurveys/
We constructed each variable of interest at the household level. Since some of the surveys asked different variants of some of the questions, we tried to define each variable in the most comparable way possible across countries. We normalized all household expenditure variables to a daily per capita level. Using the PPP conversion methodology discussed in the foreword, we converted the local currency units into 2005 world rupees. We then applied the daily poverty line cutoffs to each household's total per capita expenditures to classify households into the relevant expenditure categories. All of the tables display variable means across households within each expenditure group weighted according to the household weights provided in most surveys.
