If your claim is as it appears - "this study may not have adjusted for population growth" - you could just click the link and check, rather than spread doubt and uncertainty.

As it stands, the population has not grown 80% in the timespan given so even if they didn't control for population - which would be the most elementary mistake ever and no one would get published having made it - it still doesn't account for the effect size.

Reflexive scepticism, without any effort to verify, isn't any more useful than reflexive belief.

Interestingly, if you do click the article, you'll find that they did not control for population. The 80% figure is in absolute nominal terms. It's more than the most elementary mistake, it's downright deceptive.
