Nursing
A good source of information on Nursing is the AACN (American Association of Colleges of Nursing). They have a very informative website with many issues and current data.
Additionally, this links to a report that describes the levels of education (BS, AAS, Diploma). It is a fact sheet including the report that by 2015 - the Dept. of Health & Human Services predicts a shortage of 114,000 nurses!
