Summary measures of weighting effectiveness for post-stratification, basic raking and full raking. The summary measures are based on all 18 characteristics shown in Additional file 6, with a total of 68 categories (excluding “missing”), of which 64 and 42 categories are included in the comparisons with the ANHS and NDSHS population benchmarks, respectively. The numbers of categories with overlapping 95% confidence intervals for the ANHS estimates and the unweighted or weighted 45 and Up Study estimates were not calculated, as the ANHS data used in this work did not include confidence intervals. CI confidence interval, NDSHS National Drug Strategy Household Survey, ANHS Australian National Health Survey.
