    Hello and welcome to epidemiology. If I were to ask you, how would you describe the burden of disease in your community, or the presence of a disease or diseases in a population, would you know what to do, what numbers to use, even what questions to ask, how would you even start that conversation? Well today that's what we're going to do, we're going to look at how we describe the presence of disease in a given population, using classic epidemiological measures. So you're going to understand the various measures of morbidity, including most famously incidence and prevalence. You're going to understand our measurements of mortality and you're going to understand how to read a population pyramid, which is one convenient, easily digestible way of visually appraising a demographic distribution of individuals in a given population. So let's go back to my original question, if you're trying to describe the presence of a disease in your community, how would you do it? What questions would you ask? Would you care about who gets the disease? Would you care about how many people get it in a given time period like a year? Would you care about how many are dying of it or your chances of dying of it if you were to catch that disease or maybe you care about of all the things that kill people in this population, how many died of this particular disease? Each one of those questions can be summarized using a different kind of measure and each one tells a little bit different, a little bit of wisdom that's separate from each other, that altogether they give a comprehensive sense of how that disease is making its way through a given population. So in descriptive epidemiology, we're seeking to summarize some of...
