This paper explores the use of smugglers by Latin American and Caribbean migrants on their journeys to North America. It is based on responses to more than 3,000 4Mi surveys conducted in Costa Rica, Honduras and Mexico in 2022 and 2023 and includes findings on profiles of migrants who hired smugglers as well as information on the services they sought and their general perceptions of smugglers. As such, this paper provides a wealth of solid empirical evidence with a view to informing the work of policymakers and humanitarian actors.
