Estimating the Value of a Country's (Region's) Chemical Industry

I am assuming the chemical industry revenues that a country (region) is able to generate divided by the country's (region’s) population can be useful as a measure of that country’s (region’s) chemical industry value added to the country (region).   If this assumption is correct, then the following table is an estimate of the chemical industry value for various countries (regions):

area	revenues usd 2015	population 2015	revenues per person
Germany	205,000,000,000	81,000,000	2,531
South Korea	120,000,000,000	50,000,000	2,400
Gulf Cooperation Council countries	120,000,000,000	51,000,000	2,353
Japan	210,000,000,000	127,000,000	1,654
United States	490,000,000,000	319,000,000	1,536
NAFTA	625,000,000,000	441,000,000	1,417
European Union	660,000,000,000	508,000,000	1,299
France	85,000,000,000	66,000,000	1,288
China	1,100,000,000,000	1,400,000,000	786
Russia	85,000,000,000	144,000,000	590
Canada	20,000,000,000	35,000,000	571
Global	3,500,000,000,000	7,400,000,000	473
Brazil	85,000,000,000	200,000,000	425
South America	160,000,000,000	423,000,000	378
Asia	1,600,000,000,000	4,400,000,000	364
India	70,000,000,000	1,300,000,000	54

The table suggests that China’s chemical industry is about 14 times more valuable for China than India’s chemical industry is for India ($786 revenue per person vs. $54 revenue per person; 786/54 = 14.56).   And Germany’s chemical industry produces about twice the value for Germany as France’s chemical industry produces for France ($2531 revenue per person/$1,288 revenue per person = 1.97).

The Internet was used to find chemical revenues and population amounts.

A reasonably accurate measurement that indicates the value added by a country’s chemical industry to the country might be useful in measuring progress a country is making over time in increasing its chemical industry value.   Simply increasing a country’s revenues may not be sufficient in understanding how much value is being added by that increase.   Relating (rating) the increase to per persons could be more useful.
