It's right in the article: "The percentage of U.S. adults who report having been diagnosed with depression at some point in their lifetime has reached 29.0%"

To your point on suicide, though. The OECD has some data: https://en.wikipedia.org/wiki/Suicide_in_the_United_States#/... .. It's hard to say. US is flat. Norway is up a bit. Most countries are down or flat. I don't see any particular upward trend over the past 60 years.

Wow those numbers are counter-intuitive and in stark contrast to the mainstream zeitgeist. I think it's fair to say rates are up somewhat in the US (along with many other social ills) but for many other western countries they have been stable.

Breaking down the US statistics into demographics makes for some disturbing yet interesting reading https://www.cdc.gov/nchs/products/databriefs/db433.htm. Seems like the bulk of the growth has been older men (trending down) and women aged 15-24 (a shocking 87% increase from 2007).

here is the last some years from wikipedia (WHO suicide + mental health per 100k starting @ 2000 https://en.wikipedia.org/wiki/List_of_countries_by_suicide_r...)

16.4 16.9 17.3 17.1 17.2 17.1 17.5 17.7 18.1 18.1 18.5 18.9 18.9 18.8 19.2 19.9 21.2 22.5 21.8 22.4

and OECD (per 100k intentional self harm starting @ 2010 https://stats.oecd.org/Index.aspx?ThemeTreeId=9)
