We will start by discussing the definitions of public health and epidemiology and discuss what components of individuals and their lives that we must address in order to optimize their health and well-being. In this section, we will also introduce the hands-on exercise for this course.

In this module, we will examine the definitions for and sources of the core numeric values we need to describe the health and well-being of a population, which are numerators, the counts of an event or disease, and the denominator, the population from which events are drawn. We will then manipulate those numbers to derive ratios, proportions, and rates, which are core measures used to describe the burden of public health problems.

In this module, we will explore the tool of data visualization, understand basic components of effective visualizations, and walk through practical exercises of identifying strengths and weaknesses of specific visualizations towards meeting their stated goals. You will then have the opportunity to create a data visualization from data regarding risk factors for common public health problems using the global disease-burden database of the Institute for Health Metrics and Evaluation.
