This table reports means and 95% confidence intervals for household level information from each of the South African Income and Expenditure Surveys used in the analysis. The WHO definition of food expenditure does not include alcohol, tobacco and food purchased away from home. The WB definition does include alcohol, tobacco and food purchased away from home, which explains their differences. Out-of-pocket payments are those related to health expenditure, but does not include health insurance premiums or costs covered by third-party payers. Table prepared with xtable package in R [40].
