News on being overdraft in the Netherlands

the AD had some news on the overdraft behaviour of the Dutch. One third of the public is never in the red on its account. One third only sometimes. 17 % often and 11% always. The amount of money involved is about 8 billion euro; it's unlikely that (as the article stated) this full 8 billion wouldbe unagreed overdraft. It's more likely that a huge amount of that money is agreed lending via the payment account. But figures in this respect are scarce.
