The correlation between per capita gross domestic product based on purchasing power parity (GDP PPP) and GDP PPP per area in Asia is moderate.  The three largest economies on a per capita basis have either a moderate or high per area GDP relative to other countries on the continent.

The chart above shows economic output as it relates to arable land.  The countries to the top left have a larger ratio of gross domestic product (GDP) to arable land, while countries to the bottom right have a smaller ratio of GDP to arable land.  Singapore, Hong Kong, and Bahrain have the largest ratio of GDP to area whereas Afghanistan, Cambodia, and Kazakhstan have the smallest ratio of GDP to area.

The chart above shows economic output as it relates to land area.  The countries to the top left of the diagonal line have a gross domestic product (GDP) of over one million international dollars per square kilometer, while countries to the bottom right have a GDP that is less than one million dollars per square kilometer.  Singapore, Hong Kong, and Bahrain have the largest ratio of GDP to area whereas Mongolia, Afghanistan, and Yemen have the smallest ratio of GDP to area.

In Asia, the inverse correlation between the strength of the shadow economy and the minimum wage is very weak.  There is no real relationship between the strength of the shadow economy and minimum wage.

In Asia, the correlation between economic strength and the minimum wage is somewhat strong.  The majority of nations on the continent have a per capita GDP PPP below 30,000 international dollars and a minimum wage below 10,000 international dollars.  The only countries that surpass both of these numbers are Kuwait, Oman, Japan, South Korea, Israel, and Turkey.

In Asia, the correlation between economic strength and the strength of the shadow economy is pretty weak.  Every country studied on the continent - excluding Thailand and Georgia - has a shadow economy that takes up at most one-half of its overall economy.
