Suicidal talk on Twitter mirrors state suicide rates

Researchers used Twitter data to identify 37,717 troubling tweets from 28,088 unique users, strongly correlating with actual suicide rates. The study suggests using social media as a complement to existing suicide prevention efforts, particularly on platforms like Twitter where public tweets can be addressed and responded to.
