"The United States Code is the official codification of the general and permanent laws of the United States of America. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second Session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First Session, enacted between January 2, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 U.S.C. 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office"--Preface.

Since initiating market reforms in 1978, China has shifted from a centrally-planned to a more market-based economy and has experienced rapid economic and social development. GDP growth has averaged nearly 10 percent a year--the fastest sustained expansion by a major economy in history--and has lifted more than 800 million people out of poverty. China reached all the Millennium Development Goals (MDGs) by 2015 and made a major contribution to the achievement of the MDGs globally. Although China's GDP growth has gradually showed since 2012, it is still impressive by current global standards. With a population of 1.3 billion, China is the second largest economy and is increasingly playing an important and influential role in development and in the global economy. China has been the largest single contributor to world growth since the global financial crisis of 2008. Yet China remains a developing country (its per capita income is still a fraction of that in advanced countries) and its market reforms are incomplete. According to China's current poverty standard (per capita rural net income of RMB 2,300 per year in 2010 constant prices), there were 55 million poor in rural areas in 2015. Rapid economic ascendance has brought on many challenges as well, including high inequality; rapid urbanization; challenges to environmental sustainability; and external imbalances. China also faces demographic pressures related to an aging population and the internal migration of labor. Significant policy adjustments are required in order for China's growth to be sustainable. Experience shows that transitioning from middle-income to high-income status can be more difficult than moving up from low to middle income.

Clean energy innovation is central to the fight against climate change. To rise to this challenge, the United States should launch a National Energy Innovation Mission. Led by the president and authorized by Congress, this mission should harness the nation's unmatched innovative capabilities-at research universities, federal laboratories, and private firms (both large and small), in all regions of the country-to speed the progress of clean energy technologies. To jumpstart this mission and unlock a virtuous cycle of public and private investment, the US federal government should triple its funding for energy research, development, and demonstration (RD&D) over the next five years to $25 billion by 2025. "Energizing America" offers policymakers a strategic framework to build a growing RD&D portfolio over the next five years, detailed fundingproposals across the full spectrum of critical energy technologies, and recommendations for immediate action.

One-in-seven adults and one-in-five children in the United States live in poverty. Individuals and families living in povertyÊnot only lack basic, material necessities, but they are also disproportionally afflicted by many social and economic challenges. Some of these challenges include the increased possibility of an unstable home situation, inadequate education opportunities at all levels, and a high chance of crime and victimization. Given this growing social, economic, and political concern, The Hamilton Project at Brookings asked academic experts to develop policy proposals confronting the various challenges of AmericaÕs poorest citizens, and to introduce innovative approaches to addressing poverty.ÊWhen combined, the scope and impact of these proposals has the potential to vastly improve the lives of the poor. The resulting 14 policy memos are included in The Hamilton ProjectÕs Policies to Address Poverty in America. The main areas of focus include promoting early childhood development, supporting disadvantaged youth, building worker skills, and improving safety net and work support.
