Via, Ars Psychiatrica. A quote from the article he linked:
If surveys conducted by physician recruiting companies accurately reflect current trends in the job market, the news is very good for psychiatrists—and less promising for many patients with mental health disorders. Chief among those who may not receive the psychiatric care they need are children and adolescents and people who live in areas that are not densely populated.
Also,
The Bureau of Health Professions predicts that demand for general psychiatry services will have increased nearly 20% between 1995 and 2020. The Bureau also foresees a 100% increase in the need for child and adolescent psychiatric services during that period.
I think one of the reasons that fewer American medical students are going into Psychiatry these days is because it is turning into more of a pill-pushing and check-list diagnosing specialty than the "understand the whole person in depth" specialty that I became interested in.
