U.S. GDP in billions:
President Trump doubled the growth of the Obola administration in their first three years. Obozo=12.5%, PDJT=25%.
You do need to be accurate about 2013-6 vs 2016-9
Obammunism 2013-6: 18707 / 16784 = 1.1146 = +11.5%
Trumpism 2016-9: 21427 / 18707 = 1.1454 = +14.5%
US Population 2013-6 323.1 / 316.1M = +2.21%, 2016-9 328.2M / 323.1M = +1.58%, 2013-9 +3.83%
US Inflation 2013-6 6.08%, 2016-9 6.33%, 2013-9 12.79%
US GDP growth per capita in constant 2013 dollars:
Obammunism: 54580 / 53097 = 1.0279 = +2.79%
Trumpism: 57883 / 54580 = 1.0605 = +6.05%
6.05 / 2.79 = X2.168
Trump therefore MORE THAN DOUBLED real per capita income growth over Obammunism (X 2.168)
Hope that helps.
