Exactly what so many people seem to missing about all the hubub around presidency is the deep state is real, our bureaucracy for good and ill are quite resilient.
Just because you change out the man at the top and couple handfuls of his direct reports does not suddenly mean all the procedures, methods, systems, opinions, etc in use by all the 2,804,000+ federal workers and enumerable contractors both direct and corporate suddenly change too. That stuff is cultural and other than a few hot button issues that might get attention from POTUS directly takes decades to change, literally outlasting a single Presidents term of office in many cases.
In a lot a ways we are still feeling the effects of not exactly policy but popular opinion that dates to the Clinton Presidency and that of Gorge W Bush. People choose to get into civil service or not often depending on their admiration or lack their of for the top man in charge at the time they are ready to start a career. The people who started their careers in the late 90s and early 2000s are now the folks who have risen to positions where they are decision makers and mid-level bureaucrats. We have yet to see the real influence of Obama's millennial voters here yet (sadly IMHO, not looking forward to that all).
So the data is probably as trustworthy as it was 4 weeks or 4 years ago. Its probably as trustworthy as it was 8 years ago, or 16 or 20. That is to say its really not very trustworthy at all but probably less bias than you might imagine. There is a constant battle being fought between the left and right with the pendulum swinging both ways ever 8 years or so, but not as a far either way as the top men appear to swing. The real issue is that assumptions on either side are never really challenged or well examined because of the tug of war fought over the superficial stuff. So some labor statistic remains calculated they way it has been for the last 40 years when some probably well meaning person made a judgement call based on the information they had at hand. It never gets revisited in a serious scientific way because everyone is to busy doing studies and bickering over a handful of top line numbers that make for good headlines like the employment rate.
