The nursing shortage in USA has been fairly well-publicized. According to a report from the U.S. Department of Health and Human services, there was a shortage of 110,000 RNs in 2000, or about 6 percent of the national demand. The shortage is expected to grow to 29 percent by 2020.

What's causing this dramatic shortage? For one thing, the report states there will be an 18 percent increase in the population by 2012. Plus, the aging of the baby boomers will result in a larger proportion of elderly people. To make matters worse, after 2011 the number of nurses leaving the profession is expected to exceed the number entering it.

Nursing salaries are increasing to help boost interest. The starting salary for registered nurses was nearly $39,000 in an April 2005 survey by the National Association of Colleges and Employers. According to the BLS, median annual salaries were $53,640 in November 2004.
