(1) If the Yuan Competes with the Dollar; The yuan’s rise will challenge America, but not before China changes.

My comment:
(a) View the graphic only.
(b) The first panel of the graphic says, "1820-1913[:] America’s economy surge[;] US economy takes off, yet the pound remains the world's dominant currency"
(i) Please take notice the horizontal or x-axis is NOT linear. If it were, America’s real GDP growth rate (nominal, calculated by dollar) would not be so steep. Economics textbook show the average rate for decades on either side of the turn of the twentieth century was about 2$ annually.
(ii)
(A) The GDP data of course comes from the late Angus Maddison. See Angus Maddison statistics of the ten largest economies by GDP (PPP)
https://en.wikipedia.org/wiki/An ... t_economies_by_GDP_(PPP)
(GDP (PPP) in millions of 1990 International Dollars [which is US dollar]: 1870 China 189,470, UK 100,180, US 98,374, Russian Empire 83,646)
(B)
* population in 1870: US 38,555,983 (census)
* Digest of the English Census of 1871. Census Office, Great Britain (1873), at page 7
https://books.google.com/books?i ... nepage&q=Census in the United Kingdom 1871 total population&f=false
("United Kingdom 31.628.338")
That explains why UK hesitated to declare war on US during the American Civil War.
