May is Mental Health Month again, so it’s also a good time to review the mental health statistics behind mental illness. Some of the statistics going around aren’t entirely accurate, because they’re based upon outdated web pages on the National Institute of Mental Health (NIMH) website. This misinformation is then propagated by well-meaning people and organizations, including NAMI and others. Sadly, the NIMH website is not as accurate or up-to-date as people like to think it is (I think that because it’s a government resource, people just assume it’s accurate and correct).
For instance, the NIMH Statistics page puts data into context of 2004 Census data. Well, it’s 2010, not 2004, and we have more up-to-date Census data. Also according to the more recent NCS-R data, it’s not really 1 in 4 Americans who could be diagnosed with a mental disorder in any given year — it’s 1 in 3!
