Estimating the Size of Hidden Populations Using Snowball Sampling

Abstract:
Snowball sampling is a term used for sampling procedures that allow the sampled units to provide information not only about themselves but also about other units. This might be advantageous when rare properties are of interest. This article illustrates snowball sample situations and discusses various modelling and estimation problems in this context. The problem of estimating the size of a population is discussed for both design-based and model-based approaches. An application to a study of heroin use is included. Simulation results are provided for comparing and evaluating various estimators.

Keywords:
Network sampling; random graphs; link-tracing designs.
