The U.S. Department of Homeland Security (DHS) is responsible for securing and managing the nation's borders. Over the past decade, DHS has dramatically stepped up its enforcement efforts at the U.S.-Mexico border, increasing the number of U.S. Border patrol (USBP) agents, expanding the deployment of technological assets, and implementing a variety of "consequence programs" intended to deter illegal immigration. During this same period, there has also been a sharp decline in the number of unauthorized migrants apprehended at the border. Trends in total apprehensions do not, however, by themselves speak to the effectiveness of DHS's investments in immigration enforcement. In particular, to evaluate whether heightened enforcement efforts have contributed to reducing the flow of undocumented migrants, it is critical to estimate the number of border-crossing attempts during the same period for which apprehensions data are available. With these issues in mind, DHS charged the National Research Council (NRC) with providing guidance on the use of surveys and other methodologies to estimate the number of unauthorized crossings at the U.S.-Mexico border, preferably by geographic region and on a quarterly basis. Options for Estimating Illegal Entries at the U.S.-Mexico Border focuses on Mexican migrants since Mexican nationals account for the vast majority (around 90 percent) of attempted unauthorized border crossings across the U.S.-Mexico border.

The authors examine U.S. efforts to prevent illegal immigration to the United States. Although the United States has witnessed a sharp drop in illegal border crossings in the past decade alongside an enormous increase in government activities to prevent illegal immigration, there remains little understanding of the role enforcement has played. Better data and analyses to assist lawmakers in crafting more successful policies and to support administration officials in implementing these policies are long overdue.

This comprehensive explanation of the U.S. government's role in economics will be an eye-opener for anyone who wants to understand exactly what the government does—and doesn't do—in this most critical area. Most people, including many economists, are not aware of the great variety of crucial tasks and invaluable analyses undertaken by government economists. This three-volume set will fill that gap with an all-encompassing overview of the major economics-related work the government performs across all of its agencies and offices. With 45 chapters written by 61 leading experts, the work covers every major topic in government economics, including such diverse areas as monetary policy, defense spending, social assistance, international trade, antitrust, and environmental protection. In addition to entries by those who teach economics, the compendium also features candid observations from government insiders to help readers grasp how things really work. But readers will not only gain insight into specific fields and topics, they will also be able to better understand the big picture and how its pieces fit together. This unique and far-reaching set often challenges conventional wisdom even as it presents a novel synthesis of the government's research, analysis—and actions.

The Trump Paradox: Migration, Trade, and Racial Politics in US-Mexico Integration explores one of the most complex and unequal cross-border relations in the world, in light of both a twenty-first-century political economy and the rise of Donald Trump. Despite the trillion-plus dollar contribution of Latinos to the US GDP, political leaders have paradoxically stirred racial resentment around immigrants just as immigration from Mexico has reached net zero. With a roster of state-of-the-art scholars from both Mexico and the US, The Trump Paradox explores a dilemma for a divided nation such as the US: in order for its economy to continue flourishing, it needs immigrants and trade.

In 1975, Texas adopted a law allowing school districts to bar children from public schools if they were in the United States unlawfully. The US Supreme Court responded in 1982 with a landmark decision, Plyler v. Doe, that kept open the schoolhouse doors, allowing these children to get the education that state law would have denied. The Court established a child's constitutional right to attend public elementary and secondary schools, regardless of immigration status. With Plyler, three questions emerged that have remained central to the national conversation about immigration outside the law: What does it mean to be in the country unlawfully? What is the role of state and local governments in dealing with unauthorized migration? Are unauthorized migrants "Americans in waiting?" Today, as the United States weighs immigration reform, debates over "illegal" or "undocumented" immigrants have become more polarized than ever. In Immigration Outside the Law, acclaimed immigration law expert Hiroshi Motomura, author of the award-winning Americans in Waiting, offers a framework for understanding why these debates are so contentious. In a reasoned, lucid, and careful discussion, he explains the history of unauthorized migration, the sources of current disagreements, and points the way toward durable answers. In his refreshingly fair-minded analysis, Motomura explains the complexities of immigration outside the law for students and scholars, policy-makers looking for constructive solutions, and anyone who cares about this contentious issue.

This report offers research and recommendations on ways to measure the overall efforts of the national border-security enterprise between ports of entry. Focusing on three missions--illegal drug control, counterterrorism, and illegal migration--this report recommends ways to measure performance of U.S. border-security efforts in terms of interdiction, deterrence, and exploiting networked intelligence.
