The results that are presented are weighted percentages or means, and their 95% confidence intervals (CI), together with the total number of respondents (N is unweighted). The use of weighting factors adjusts for differences between the survey sample and the real population, in terms of the distribution by age, sex, size of the household and province. By weighting the data the results are representative for the total population, at national, regional and provincial level.
The weighting factors have been adapted after the publication of the final report that you can find on the HIS website
. These changes were needed to better reflect the distribution of the population at the the household level. This may result in small differences in the results - only for the indicators calculated at the household level - presented in the final report and the present interactive website.
