- This map has the Robinson projection divided into 18,620 squares,
showing which ones produce more than US$100 billion in GDP,
according to Brookings in 2012.
- It should be noted that because
the Robinson projection is not equal-area,
the squares are not equal in size. The area of a square varies from
around 27,500 sq. km. near Jakarta to 30,000 sq. km. near St. Petersburg.
- The area in orange consists of 197 squares. In total they
generated an estimated $32 trillion in 2012, 45% of the world's GDP.
- Many squares' GDP far exceeded $100 billion. The largest of these were around Tokyo and New York, both of which exceeded $1 trillion.
