Explore the Data
Take a moment to familiarize yourself with some basic data and statistics terms and best practices.
- Prevalence: Prevalence is the number of people within a population that has a particular disease or condition at one point in time. Prevalence is most often represented as a percentage of the population.
- Incidence: Incidence is the number of people within a population that develop a particular disease or condition within a certain amount of time (i.e., over the course of a month or a year). Sometimes the incidence is referred to as the number of “new cases”.
- Rate: A rate is a measure of how often something occurs (like a disease) within a population over a specific amount of time. Rates are used in public health to compare the frequency of a disease to other communities or among different groups of people.
- Morbidity: Morbidity is another word for illness, but it can also be a disability or an injury. A person can have numerous morbidities at the same time; this is referred to as comorbidities. Prevalence is commonly used as a measure of morbidity within a population.
- Mortality: Mortality is another word for death. It is the number of deaths caused by a certain disease or condition divided by the total population.
