美国墨西哥移民的人口效应评析

作为一个移民国家,多样化的种族/民族构成一直是美国人口结构的一个显著特征,外来移民始终是改变美国人口结构和布局的一个重要因素。近几十年以来,墨西哥裔人成为美国人口增长最快的族群之一,这部分人口主要由两种成分组成:出生于美国的墨西哥裔人和来自墨西哥的移民。作为拉美裔群体中最大的组成部分,墨西哥裔占全部拉美裔人口2/3左右;目前,墨西哥移民在美国全部外来人口中所占份额最大,达到30%;墨裔人在美国总人口中的比重逐年上升。墨裔人口不断膨胀源于其较高的生育率和移民的持续增加。墨西哥移民增加了美国的外国出生人口的数量;改变了美国人口的种族/民族构成,给美国带来了空前的族群异质性;人口多元化还影响到种族/民族关系。

Political Science and U.S. Health Policy in the Era of the Affordable Care Act

Few laws have a profound and lasting impact on an entire political system. The Affordable Care Act (ACA), despite its incremental nature and bipartisan heritage, has been one of those remarkable landmarks. Even a decade after its passage, the political struggle is far from over, as the ACA is still facing near constant threats from the incumbent president, Congress, the courts, statehouses, attorneys general, and governors across the nation. How have political scientists responded to the continued struggle? This article provides an overview of the effects of health reform and the ACA on political science research since 2008. While political scientists have written much about the subject, coverage has been distinctly uneven within the discipline. Indeed, it has almost been entirely confined to scholars of public and health policy. Nonetheless, there have been important contributions across disciplinary fields. This article provides an overview of contributions embedded within the study of federalism, policy feedback effects, and political framing. It concludes by emphasizing the need for more engaged scholarship on health policy issues from across the entire discipline, and by highlighting other areas of study that could benefit from broader attention by political scientists.
