FiveThirtyEight's assessment of President Trump's first year:
The upshot? Few dramatic changes in either direction. Jobs in the manufacturing and coal mining industries ticked up, the trade deficit shrank a bit, and the number of murders in some big cities decreased. The uninsurance rate got worse — the only change in the opposite direction of Trump’s goal. The biggest movement in the direction Trump hoped to see was the increase in oil and natural gas production.
So, according to these measures, Trump has had a reasonably good year. Of course, that doesn’t mean Trump was personally responsible for all of this change — in fact, many of these trends began long before Trump was elected. But presidents often get credited with whatever happens while they’re in office anyway.
