Answer:
International trade has been declining as a share of the economy.
Step-by-step explanation:
International trade as a percentage of the United States GDP increased slowly over the second half of the twentieth century, and the first decade of the twentieth-first century, from 9.17% in 1960, to a peak of 30.79% in 2011. However, in the last years, this percentage has been gradually declining. For example, in 2017, international trade as percentage of GDP was 27.09%.
