Document Summary
Epidemiology: addresses human populations with respect to their health: frequency quantified rate of its occurrence, prevalence proportion of individuals afflicted by the illness at a particular time health state. Incidence proportion of individuals that receive the illness at a particular time event. Incidence density number of cases diagnosed in a given population in time. Endemic (one region) versus epidemic(multiple regions) versus pandemic (global) E. g. causal (attributable) rate ratio such as the study of cigarette smoking in the etiology of lung cancer. X causes a disease y if we stop x what does it do for disease y e. x. cigarette smoking and lung cancer. Many different disciplines can be involved in this field of epidemiology. Main dragging force is fertility average number of children women has. High projection around 2. 6 children per woman. Medium projection 2. 1 children per woman. Lowest projection 1. 6 children per woman: dynamics of population growth. Immigration and emigration doesn"t matter, birth rates and death rates matter.
