Millionaire Cities

When I used to teach about settlement, and we got onto the idea of 'millionaire cities', there were always students who asked whether they were cities where millionaires lived.

The Guardian's DATABLOG has now released a range of maps and visualisations based on the cities which are homes to the world's millionaires and billionaires.
They make interesting viewing, and would be particularly relevant to some topics, for example at Edexcel 'A' level.
