As the population continues to grow and age, more and more people will be in need of some sort of assistance. Shortages of health-care workers such as physicians, nurses, therapists, social workers, and dentists are expected to continue as older workers retire and lower numbers of new health-care workers enter the fields. At the present time, the impact of these shortages places the burden on individuals and their families to meet the needs for care and assistance. This impact is only going to increase as the population grows and ages.
