Notes:
Timeseries are combined where methods are similar over the time span. Spain and Luxembourg each have two different time series. For more details see [Table PDU-1 to PDU-3] in the 2005 statistical bulletin. Target groups may vary owing to different methods and data sources; therefore comparisons should be made with caution. In some countries data are insufficient to report.
