• The survey comprising questions B1-B13 was conducted between May 25 and June 8, 2018 with 23,249 adults across 28 countries (the same as above plus Colombia).

• All survey respondents are aged 18-64 in Canada and the U.S. and 16-64 in all other countries.

• Weighting has been employed to balance demographics and ensure that the sample’s composition reflects that of the adult population according to the most recent country census data.

• A survey with an unweighted probability sample of this size would have an estimated margin of error of +/- 3.1 percentage points for a sample of 1,000 and an estimated margin of error of +/- 4.5 percentage points for a 500 sample 19 times out of 20.
