  • Values are percentages unless otherwise stated.

  • All figures are weighted for sampling probabilities and differential non-response.

  • *All sample sizes are provided unweighted. Note sample numbers for each correlate do not always sum to the total sample number due to missing data.

  • †Never/rarely=never – once or twice a year; regularly=once every 2 months – twice a week; frequently=3 days a week – almost every day.

  • SD, standard deviation.
