It's important to note, also, that 'jobless households' also include, for example, a retired couple living alone, or a house full of full-time students: both categories are more likely in the UK than in the rest of the EU where many more retired people and students live within the family unit where there's an earner resident. People are also much more likely to live alone in the UK, so a 'household' constitutes one person.
I wish people would read a little more than the Telegraph sometimes.
