Trend analysis

The Trend Analysis tool allows you to study the survey data by different respondent groups, showing all available trend data. Please note that the trend data for surveys from January 2009 to March 2011 are available separately to the 2011-2012 survey data. The results of the 2011-12 survey cannot be compared to previous years, even where questions remain the same. This is due to the changes to the questionnaire design and survey frequency, as well as the change to the weighting methodology.

1. Current data (July - September 2011)
