G20 means something totally different in the place we want you to identify.

It's a zipcode - or a 'postcode' in this part of the world.

This postcode identifies an inner-city area that's been hit hard by the global economic downturn.

Unemployment, poverty and shuttered shops are the norm in this part of town.

And a recent rise in prices has only made things worse for the people that live there.

The area in question isn't in the developing world.

In fact, it's not so far from London, where the political G20 is gathering.

So - locate the postcode G20, if you can....
