Sampling methods to study street children often rely on convenience approaches. Respondent-driven sampling (RDS) is a relatively new methodology for sampling hard-to-reach populations utilizing peer-driven recruitment. It includes both field and analytical procedures to account for non-random recruitment patterns and generates statistically valid samples. This article describes RDS and assesses its effectiveness to recruit a diverse sample of street children, defined as children aged 10–17 years who engage in economic activity on the street in Tirana, Albania.
