I-Spirit Billionaires Map
According to Forbes there are 794 dollar billionaires in the world. French mapping site I-Spirit has produced a Google Map showing the location of each of them. It is possible to filter the 794 billionaires by age or country.
One of the most glaring facts this map reveals is the north/south divide in the world's wealth. Of the 794 billionaires only 40 of them seem to live south of the equator.
The I-Spirit map comes with an option to embed the map in your own website or blog.
