But it is tough to say within the last several years (as opposed to the last decade) if that's the case.
UPDATE:
Apparently the ratio is definitely increasing even within the decade.

Definitely is too strong for that noisy set.
There's always this problem with ratios of random variables--the distribution is frequently quite fat-tailed. Then you need a whole lot of data to form a good estimator.
Also the fact that it is implicitly a heteroskadistic qty in this case is a PITA.
