Per capita income is not decided by the government but UN agencies, and they keep their own data.1.25 Billion officially?
1.3 Billion unoffiially?
1.39 Billion according to neutral estimates?
What I don't get which figure do they use to calculate per capita income. Difference between 1st and 3rd figure would be more than 10% reducing 2000 dollars to 1800. Also, after contraction of 10% in economy due to covid would also decrease their per captia by anther 10% to 1620 dollars.

Please conserve those scant brain cells for some other day, our economy is not contracting by 10%.
