Notes
1,Figures may not sum due to rounding.
2,"The year on year differences should be interpreted with caution because of the precision of survey-based estimates. 95% confidence intervals (CI), a standard way of expressing the statistical accuracy of a survey-based estimate, are provided in the table. A 95% confidence interval is a range within which the true population would fall for 95% of the time the survey was repeated. If an estimate has a high error level, the corresponding confidence interval will be very wide. "
3,"Coefficients of variation (CVs), which provide another indicator of the quality of these estimates can be found in the datasets accompanying this release. "
4,"Figures have been rounded to the nearest £0.1 billion in the table (but are available to the nearest £500,000 in the datasets accompanying this release). "
