Book excerpt: This study shows that migrant smuggling routes affect every part of the world. It is based on an extensive review of existing data and literature. The study presents detailed information about key smuggling routes, such as the magnitude, the profiles of smugglers and smuggled migrants, the modus operandi of smugglers and the risks that smuggled migrants face. It shows that smugglers use land, air and sea routes - and combinations of those - in their quest to profit from people's desire to improve their lives. Smugglers also expose migrants to a range of risks; violence, theft, exploitation, sexual violence, kidnapping and even death along many routes.
