Epidemiologists are often data scavengers. Using pre-existing data can allow a study to be done more cheaply, more quickly, and often on a larger scale than if new data collection were required. This chapter considers the strengths and weaknesses of several commonly used kinds of pre-existing data, as well as some techniques for assessing and dealing with data limitations. It focuses mainly on data resources available in the United States. Topics covered include numerator data, health care utilization data, and denominator data. Exercises are provided at the end of the chapter.
