The 6.8 percent unemployment rate for black Americans in December is indeed the lowest since 1972, according to the latest monthly data that is available from the Bureau of Labor Statistics. But the rate has been in decline for several years, decreasing steadily from 16.4 percent in August 2011 to 7.8 percent in January 2017.
The December figures also do not reflect a significantly different racial unemployment gap. The black unemployment rate has consistently been double that of the white unemployment rate, and remained at that level in December. Presidents, especially in their first year, generally do not single-handedly influence the labor markets — as Mr. Trump suggests.
So does Mr. Trump deserve any credit for solid economic results? If you think the economy is driven by concrete, specific policies around taxes, spending, monetary policy and regulation, the answer is no. If you think that what really matters is the mood in the executive suite, then just maybe.
