Yes, that does seem to be the case, in spite of increased awareness, better medications, and supposedly less stigma.
And this from the peer-reviewed journal Pediatrics
RESULTS: The 12-month prevalence of MDEs increased from 8.7% in 2005 to 11.3% in 2014 in adolescents and from 8.8% to 9.6% in young adults (both P < .001). The increase was larger and statistically significant only in the age range of 12 to 20 years. The trends remained significant after adjustment for substance use disorders and sociodemographic factors. Mental health care contacts overall did not change over time; however, the use of specialty mental health providers increased in adolescents and young adults, and the use of prescription medications and inpatient hospitalizations increased in adolescents.
The Meta-Bug 
Operative word being ‘supposedly’ less stigma. I think you nailed it.
There is more stigma by the fact of social media perpetuating and replicating and ultimately even if we all hear the platitudes, we know most people think ‘you’re a weak ass / suck it up’ and as long as we know that’s what others think it makes it worse (to be depressed) and there’s few resources and the world gives us reasons (to be depressed) and fewer reasons to not be. I know that sounds bleak I don’t really mean it to, because I believe you can live a good life no matter what, but I think we should be honest as you were, and admit that the world makes it tough because if someone had cancer someone wouldn’t say ‘suck it up’ would they?
Many (it used to be most, but I don’t have any recent studies) Americans thought depressives would stop being depressed if they “just thought happy thoughts.” They really don’t understand that depression is the inability to have those thoughts, that you can’t bootstrap yourself up if there are no boots to begin with.
