Table conventions 
 
Interpreting tables:
 
All analysis excludes don’t knows/refusals unless otherwise specified.
 
‘0’ indicates less than 0.5% or no response in a particular category.
 
‘N/A’ indicates that the question was not asked in that particular sweep of the survey.
 
The base numbers (unweighted base) may vary as the figures are dependent upon whether the question was asked of all respondents.
