An AnalysisAaron S. Robertson

Manufacturing jobs tend to be good-paying, sustainable jobs

That said, is the level of imports coming into the U.S. dependent on the number of manufacturing job gains?

After all, with an increase in these jobs, and hence, more disposable income readily available, money spent on imported goods and services would theoretically increase, as well

Because we’re exporting more goods as a result of these manufacturing job gains, in theory, the favor is reciprocated by governments and foreign corporations friendly to the U.S.

In short, because we’re exporting more, we’re also importing more, through trade agreements, talks, etc.

H0: There is not a correlation between manufacturing job gains and imports between 2001-2011

H1: There is a correlation between manufacturing job gains and imports, 2001-2011

There is a correlation between manufacturing job gains and imports between 2001-2011

However, there appears to be a fairly strong negative correlation, with r= -0.750
