5%, 25%, 50% Revisited

I had written earlier that when I think of the United States' place in the world, I like to keep 3 percentages in mind: 5%, 25%, and 50%. I have since found a couple more, so here is the updated list.

5% numbers
---
4.6% of world population (298 million of 6.5 billion)
6.2% of land on earth (9.63 of 148.94 million sq km)

25%
---
20% of world GDP ($12.3 of $60.7 trillion)
23% of world prisoners (2.09 of 9 million)
23% of world carbon emissions (5.8 of 25.2 billion tons)
25% of world oil consumption (20 of 80.1 million bbl/day)
30% of all foreign college students study in the US (583,000 of 1.9 million)

50%
---
45% of world automotive CO2 emissions
48% of world health care spending ($1.6 of $3.3 trillion)
48% of world advertising spending ($286.4 of $602.4 billion)
49% of world military defense spending ($518 billion of $1.07 trillion)
51% of the top 100 universities in the world
55% of the Nobel prizes in science from 1950-2003 (185 of 334)


And one bonus percentage:

66% of world spending on legal services
