Abstract

Snowball sampling is a chain referral method whereby a sample is constructed from a base of initial contacts, who are asked to provide introductions to their associates, who, in turn, are asked to refer others. This process continues until a sample has been built. Snowball sampling is designed for the explicit purpose of obtaining systematic information in situations in which convenience sampling is inappropriate and probability sampling is unrealistic.
