According to the OOH, employment of social workers is expected to increase much faster than the average for all occupations, by 25 percent from 2010 to 2020, largely because of the growing elderly population's demand for health and family services. Overall employment of social workers who specialize in child, family and school is expected to grow by 20 percent (faster than the average for all occupations). Those who specialize in mental health and substance abuse are expected to grow by 31 percent (much faster than the average). Growth of medical and public health social workers is expected to be 34 percent (also, much faster than the average).
