Anxiety increased from 5.12% in 2008 to 6.68% in 2018 (p<.0001) among adult Americans. Stratification by age revealed the most notable increase from 7.97% to 14.66% among respondents 18-25 years old (p<.001), which was a more rapid increase than among 26-34 and 35-49 year olds (differential time trend p<.001). Anxiety did not significantly increase among those ages 50 and older. Anxiety increased more rapidly among those never married and with some college education, relative to their respective counterparts. Apart from age, marital status and education, anxiety increased consistently among sociodemographic groups.
That is from a new paper by Renee D. Goodwin, Andrea H. Weinberger, June H. Kim, Melody Wu, and Sandro Galea.
You should be spending a significant portion of your time pondering these data, because it is one of the very most important social trends today, as it also helps to explain many other social trends.
