This glossary provides basic definitions for terms that have a specific meaning in the application of the capture–recapture methodology, particularly with respect to standard techniques for the application of log linear models to multiple lists. In epidemiology, capture–recapture is used for prevalence estimation. It is intended that, as well as being a central point of reference for terms used in the capture–recapture methodology, this glossary should provide a resource for those new to this methodology. It aims to provide a simple introduction using terms that should be understood by an uninitiated audience.
