Yes, Trump deserves credit on black unemployment

Is President Trump singularly responsible for the record lows in black unemployment rates?

No.

But does Trump deserve significant credit for those low rates?

Yes.

I note this in light of Trump's tweet on Monday celebrating his record on black unemployment rates. But what does the data actually say?
Well, most importantly, the numbers show that Trump is broadly correct. While the black labor participation rate remains lower than its historic highs in the late 1990s, it has improved under Trump. And while the December 2019 black unemployment rate ticked up slightly to 5.9%, it reached just 5.4% in August and is down from 7.5% at the start of Trump's term in January 2017.
