How widespread is learned-helplessness in society?

The problem with measuring learned helplessness is that while we know it exists and is related to dorsal raphe nucleus 5-HT neurons in the brain, we have no official designation of it as a mental disorder and official study to measure it. However, there is a correlation between depression and learned helplessness, so we might be able to use depression statistics in order to measure the amount of learned helplessness in society. 7.6% of people 12 years and older experience depression in the United States in any two week period and 9.4% of American patients visiting the hospital in 2017 experienced depression. Globally, over 264 million people suffer from depression and thus, they are more likely to suffer from learned helplessness.
