A 2-day public workshop on estimating the prevalence of human trafficking in the United States was held by the Committee on National Statistics in collaboration with the Committee on Population April 8-9, 2019. The workshop explored current and innovative sampling methods, technological approaches, and analytical strategies for estimating the prevalence of sex and labor trafficking in vulnerable populations. The workshop, sponsored by the Office on Women's Health at the Department of Health and Human Services (HHS), brought together statisticians, survey methodologists, researchers, public health practitioners, and other experts who work closely with human trafficking data or with the survivors of trafficking.

Participants addressed the current state of research on human trafficking, advancements in data collection, and gaps in the data. They discussed international practices and global trends in human trafficking prevalence estimation and considered ways in which collaborations across agencies and among the U.S. government and private-sector organizations have advanced counter-trafficking efforts. The workshop highlighted the importance of understanding the scope of human trafficking in order to inform and receive support from policy makers and change agents.
