I thought about this when I read that statistic.
I assume its because a lot more singles than albums are purchased and I bet the stat for Singles would be more than reversed

I think almost no singles are bought on "hard formats" any more
but I think, financially, albums still hugely dominate. I could be wrong.

No singles are bought on hard formats because there are no shops in which to buy them.
So in order to get hold of a 7" you have to add on £2-£3 postage on top of the £3-£5 price of the single.
Not really worth it for two songs when you can download them for 50p or whatever it is these things cost.

In order to get hold of a 7" I'd have to cut off an inch and a half
LOLLERs.
