The definition of the demographics of an aging population needs to be clarified.
The fertility rate in the USA (the number of births) is decreasing while there is, also, developing an increasing proportion of the population that is older. The result of the aforementioned will be that there will be fewer individuals available to go to nursing school while there will be an increasing demand for medical professionals.
The educational system in the USA is, also, increasingly deficient with regard to producing high school graduates with the intellectual skills requisite for entry into nursing school and successfully completing the same.
Without addressing these fundamental issues concomitant with work place issues such as job security, working conditions, advancement opportunities, and respectful treatment, the means utilized to efficaciously and appropriately address the looming nursing shortage will prove to be ineffectual.
