London's 32 boroughs spent an estimated £126m on mental health services in 1997-98 - more than the combined total for all other metropolitan districts, and almost a quarter of the entire local government spend on such services across the whole of England and Wales.

Of the 351,767 people claiming to be homeless in 1996-97 (local authorities accepted only 136,639 such claims), 68,239 were in London and 148,255 in non-metropolitan districts - yet the capital spent more than twice as much on homelessness because its councils had little housing stock of their own.

It looks good on the screen as well. But what a shame that the website designer seemed to believe that everyone would have a 24-inch screen on which to view it.
For most of us, using SIS is going to mean an awful lot of scrolling.
