RN employment is expected to increase from 2012 to 2022, with the health care sector growing due to factors like an aging population and technological advances.
Step-by-step explanation:
RN (Registered Nurse) employment is expected to increase from 2012 to 2022. Health care professions, including nursing, often see growth due to a variety of factors such as an aging population, increased access to health insurance, and advancements in medical technology. These factors contribute to creating more job opportunities for registered nurses throughout the healthcare industry.
Looking at the broader picture of employment rates, over the long term, the U.S. unemployment rate has had periods of both increase and decrease, but it does not show a clear long-term trend towards just rising or falling. Various economic cycles, policy changes, and external events have influenced these rates over the decades.
The natural rate of unemployment, which includes frictional and structural unemployment, does tend to change over time due to factors such as technology and demographics, but it may not have a predictable long-term trend.
