  1. aBelgium: population data for the whole country (Flanders and Wallonia)
  2. bBold numbers represent ≤ 10%-point difference between population and response. Out of 155 cells, 58 are within the 10%-point band. Six countries have all cells within the 10%-point band; one country has 4 cells within the 10%-point band; four countries have 3 cells within the 10%-point band; 7 countries have 2 cells within the 10%-point band; 7 countries have 1 cell within the 10%-point band; and 6 have no cells within the 10%-point band
