The course presents quantitative research methods to conduct research on rare, marginal, hidden, and elusive populations (also called hard-to-reach populations), such as, for example, sex workers, illegal immigrants, victims of trafficking, and drug users. After introducing and defining hard-to-reach populations, the course describes a wide range of methods: techniques to estimate the size of hard-to-reach populations (capture-recapture), sampling strategies (Respondent Driven Sampling, RDS), and data collection methods to ask questions about sensitive topics, including indirect questioning techniques (e.g. the Item Count Technique, the Randomised Response Technique, etc). Ethical issues arising when investigating hard-to-reach populations will be discussed. The course is applied in nature and includes examples from empirical research.
