"Our new analysis of goods and services exports for 381 metropolitan areas shows that, in 2016, exports did not drive significant economic growth in most parts of the country. The export slowdown was linked to declines in manufacturing exports, particularly in the industrial Midwest.
The recent decline marks a departure from the national post-recession trend. Between 2009 and 2014, exports accounted for 26 percent of the growth in U.S. gross domestic product (GDP). But U.S. exports declined in 2015 and again in 2016, hampered by a strong dollar and sagging global demand. Exports recovered slightly in the first quarter of 2017, but not enough to counteract losses in the previous two years."
