During the 2016 presidential race, Donald Trump promised Americans that, as their president, he would usher in âtremendousâ economic expansion of as much as six percent. While that growth rate has not materialized, the USAâs gross domestic product (GDP) grew at an annual rate of 4.1% in the second quarter of 2018. Thatâs respectable growth, so president Trump boasted that âwe have accomplished an economic turnaround of historic proportions.â Thatâs true if you look back only the year and a half that Trump has occupied the Oval Office. However, if your historical perspective is longer, the proportion of the GDPâs growth is not so large after all (click chart below to view full size).

Other than Q2 2018, the GDP has grown less than three percent each quarter since Trumpâs inauguration. In comparison:
- There were four quarters during president Barack Obamaâs term in which the growth rate exceeded 4.1%âonce even surpassing five percent. And Obama had to start his term with the economy mired in the Great Recession that president Bush handed off to him.
- The GDP growth was larger yet during president Bill Clintonâs administration. Trumpâs best quarter so far would have been only the thirteenth best quarter during Clintonâs term, when eight quarters were larger than five percent and one even reached 7.5%. Now thatâs HUGE by historic proportions!
Itâs also important to understand that the Bureau of Economic Analysis reports quarterly results on an annualized basis. That means the growth rate it reports for each quarter is the amount the GDP would grow if the rate in the given quarter were to be sustained for an entire fiscal year. So the 4.1% annual growth rate Trump is touting is much larger than the actual rate the GDP has grown for any full year he has been POTUS.
Yes, growth was strong in Q2 2018. But the GDP only grew 2.2% (annualized) in the first quarter of this year. Therefore, for the GDP to achieve an actual growth rate of 4.1% for the full fiscal year 2018, the quarterly growth will have to average over five percent (annualized) in both of the remaining quarters of fiscal year 2018. It would be nice for the economy to grow that fast this year but, with the growing headwinds of an escalating trade war, it will be a very tall order.
So Americans should be pleased to see the strong growth the GDP underwent last quarter. But they need to keep in mind that itâs only a snapshot of a single quarter. In retrospect, the growth of the GDP appears larger than it was.
