The National Academy of Sciences held a two-day public workshop on Estimating the Prevalence of Human Trafficking in the United States. The workshop brought together statisticians, survey methodologists, demographers and researchers who have studied this population, as well as public health and other experts who have experience with innovative data collection methods. The workshop explored:
♦ Statistical methods successfully applied to estimating the prevalence of human trafficking in other countries, such as the UK and the Netherlands.
♦ Innovative methodologies applied to estimate the prevalence of human trafficking in specific areas of the U.S., including Texas, San Diego, and several major cities in the U.S.
♦ Sampling methods, including time location sampling and respondent driven sampling, which have been used to study other rare or hard-to-reach populations, such as homeless persons and people who use intravenous drugs.
♦ Definitional and measurement issues in estimating human trafficking through survey questions and administrative records systems.
♦ Methodological and ethical issues in attempting to estimate the prevalence of human trafficking in the U.S.
