 Min.= minimum purity recorded; Max. = maximum purity recorded; Mean = mean purity recorded; Mode = most frequent (typical) purity recorded. 

 Data were not available in 2006 for the un-listed EU Member States. 

 The minimum ‘zero’ values represent a value greater than zero but lower than the minimum sensitivity threshold that allows a robust estimate. 

 (1) Data reported as mode, most frequent (typical) purity, are actually the median. 

 (2) Data reported as means is actually a weighted mean. 

 (3) Data reported as means is actually the median. 

 (4) Data refer to England and Wales only.
