Migrant crisis: Italy threatens to shut ports per BBC News - terminology

This BBC report http://www.bbc.co.uk/news/world-europe-40437917 has an interestingly worded note at the end.

'A note on terminology: The BBC uses the term migrant to refer to all people on the move who have yet to complete the legal process of claiming asylum. This group includes people fleeing war-torn countries such as Syria, who are likely to be granted refugee status, as well as people who are seeking jobs and better lives, who governments are likely to rule are economic migrants.'

That's interesting, maybe the BBC could split figures in future reports so that we know what proportion of migrants are 'fleeing war-torn countries such as Syria' as opposed to those 'seeking jobs and better lives'. Maybe not...
