My Study in Political Geography

Today, out of boredom, I decided to look up rankings of countries by area, population, and population density. Here are the top 5s for each, but for more details (like the actual statistics), you'll have to look them up on your own.

AREA
1. Russia
2. Canada
3. U.S.A.
4. China
5. Brazil

POPULATION
1. China
2. India
3. U.S.A.
4. Indonesia
5. Brazil

DENSITY
1. Monaco
2. Singapore
3. Vatican City
4. Malta
5. Maldives

So I decided that I want to figure out the "most efficient" countries based on their ranks in each graph. I'm not doing this mathematically, or maybe I am, I don't know. But here's the list of the best of the biggest.

1. India (avg. rank of 9.3)
2. China (19.7)
3. Pakistan (26)
4. Indonesia (26.7)
5. Japan (29.7)
6. Nigeria (31)
7. Bangladesh (35.7)
8. Vietnam (36.3)
9. Egypt (45.7)
10. Mexico (47)
