Some amazing statistics about Singapore's GDP

All figures for area, GDP and population ["facts"] are from Wolfram Alpha, as on 14-Aug-12. The analysis and calculations are mine.

• Area of Singapore= 697 square km [can be thought of as a square with side 26.4 km]
• Area of India= 3,287,000 square km [can be thought of as a square with side 1813 km]
• Real GDP of Singapore= USD 184.6 billion in 2009 [price adjusted to 2008 USD]
• Real GDP of India= USD 1,379 billion in 2009 [price adjusted to 2008 USD]
• Real GDP per square km for Singapore= USD 264.85 million
• Real GDP per square km for India= USD 419,531
• Number of times India is larger than Singapore [area]= 4,716
• Number of times India is larger than Singapore [real GDP]= 7.5
• Interpretation #1: India is 4716 times larger than Singapore [geographical area], but India's real GDP is only 7.5 times larger. Amazing land utilization in Singapore!
• Ratio of real GDP per square km of Singapore to that of India= 631
• Interpretation #2: Singapore produces six-hundred-thirty-one times the GDP for every square km as does India!
• Caveats: We must remember that there are some inherently non-productive land areas in India, such as barren deserts, mountains, etc., and also that Singapore's population density is 17.2 times that of India. We should divide the 631 we had got by 17.2 to get 36.7, a more practical estimate of relative land utilization obtained by normalizing population density.
