Using sampled social network data to estimate the size of hidden populations 

Surveys have traditionally been based on the idea that researchers can estimate characteristics of a population by obtaining a sample of individuals and asking them to report about themselves. Network reporting surveys generalize this traditional approach by asking survey respondents to report about other people to whom they are connected. This approach can be used to study many important rare and hidden populations for which traditional survey methods are inadequate; for example, the approach has been used to estimate the size of epidemiologically important groups like sex workers, drug injectors, and men who have sex with men. It has also been used to estimate critical demographic quantities such as adult death rates. I will introduce a framework for developing estimators from network reporting surveys and then I will present some results from a nationally-representative survey experiment that my colleagues and I conducted in Rwanda.
