The search for causes

Here, epidemiology is looking for aetiological clues both within groups of individuals and within the communities they live in. It is the substance of this chapter. Applying population data to individual risk

In this, the focus moves from the population back to the individual. For example, if the annual incidence rate for schizophrenia is known in a population and if this information is age-specific, it is possible to estimate the probability that a person of a given age will develop this disorder within the next year. This is the base rate, before one starts to consider risk factors such as family history.
