This important new book reveals how the stricter US border-control activities of the past decade have affected the behavior of migrants and potential migrants in rural Mexico. The authors establish direct links between changes in immigration-control policies and changes in the decision to migrate, choice of destination, mode of entry, and inclination to participate in a temporary worker program. They also point to the unintended consequences of new control measures, such as the increasing rate of settlement among illegal migrants, higher fees paid to professional people - smugglers, increased injury and fatality rates due to clandestine entry, and changing composition of migrant flows. Collectively, they present detailed and direct evidence of the failure of post-1993 US strategy to deter unauthorized entry across the US-Mexico border, and the reasons for this failure.
