A correlation shows the degree of relationship between two variables.

What is an epidemiologist and how much do they make?

The U.S. Bureau of Labor Statistics reports that epidemiologists earn a median annual income of $70,820. Many epidemiologists will start with a salary at or around $46,870 (the median salary for the bottom 10% of wage earners), and can ultimately reach over $114,510 with experience.

What do epidemiologists do?

Epidemiologists do fieldwork to determine what causes disease or injury, what the risks are associated with health outcomes, what populations are at risk, and how to prevent further incidences of a disease, behavior, or transmission. They consider the demographic and social trends of populations in relation to a disease and injury.
