The past few decades have witnessed a historic integration of the United States into the world economy - even more so than in the first half of the twentieth century. This integration, an important element of the worldwide process of globalization, was marked by a rapid increase in the quantity of goods traded with other countries and in the number of people who immigrated to the United States. Between 1970 and 2015, the value of exports and imports as a fraction of gross domestic product (GDP) almost tripled from 11 percent to about 30 percent. The foreign-born share in our workforce tripled as well, from 5 percent to over 16 percent.
