Table and figure conventions
- Data in the tables are from the 2011 British Social Attitudes
survey unless otherwise indicated.
- Tables are percentaged as indicated by the percentage
- In tables, '*' indicates less than 0.5 per cent but greater
than zero, and '-' indicates zero.
- When findings based on the responses of fewer than 100
respondents are reported in the text, reference is made to the
small base size.
- Percentages equal to or greater than 0.5 have been rounded up
(e.g. 0.5 per cent = one per cent; 36.5 per cent = 37 per
- In many tables the proportions of respondents answering "Don't
know" or not giving an answer are not shown. This, together with
the effects of rounding and weighting, means that percentages will
not always add to 100 per cent.
- The self-completion questionnaire was not completed by all
respondents to the main questionnaire (see Technical details).
Percentage responses to the self-completion questionnaire are based
on all those who completed it.
- The bases shown in the tables (the number of respondents who
answered the question) are printed in small italics. Both the
weighted and unweighted bases are given.
- In time series line charts, survey readings are indicated by
data markers. While the line between data markers indicates an
overall pattern, where there is no data marker the position of the
line cannot be taken as an accurate reading for that year.
