Researchers from Johns Hopkins University and Aga Khan University presented findings and lessons learned about estimation strategies used to measure the prevalence of forced labor in the brick kiln industry in Sindh province of Pakistan. The research team utilized two sampling methodologies: (1) multi-stage, cluster random sampling with probability proportional to size, and (2) respondent-driven sampling. The presentation also described the impacts of the August/September 2022 floods on the brick kiln industry, on the study, and on the working and living conditions of brick-kiln workers in Pakistan, with a particular focus on impacts on forced labor.
