Epidemiology is about studying and controlling disease and injury patterns in all human beings.

Epidemiologists perform fieldwork to see what is the cause of injury and disease, what risks there are and how to stop further incidences. Epidemiologists have to understand the social and demographic trends that stem from injury and disease. The discovery and containment of major disease outbreaks, such as avian flu, often are due to the work of epidemiologists with a degree in epidemiology or related field.

You will use statistical analysis in this field, but you also must account for other factors: heredity, environment and behavior among them.

The field of epidemiology will see 6% job growth by 2024, according to BLS, and a median salary of $69,000 was typical in May 2015.

Environmental health scientists should see at least an 11% job growth increase by 2024. It is believed that increased public interest in the many dangers that are facing the environment today are driving more jobs in the field.

It is thought that much of the growth in jobs for environmental health scientists will be in private consulting companies. These organizations help their clients to monitor and manage environmental problems and to comply with EPA regulations.

The median salary for environmental health scientists was $67,500 as of May 2015.
