Public Use Data on Mexican Immigration

描述（由申请人提供）：墨西哥移民可能是当今美国决策者和公民面临的最具争议的人口问题。该提案寻求继续支持墨西哥移民项目（MMP），以提供高质量的公共使用数据，了解有证件和无证件的墨西哥移民到美国的特征和行为。迄今为止，该项目已对118个社区进行了调查，建立了一个数据库，其中包括19 726个家庭中所列的128 940人，这些家庭共有21 1988名目前和以前的移民到美国，其中13 793人在调查时没有证件。数据将从MMP网站上发布，该网站目前有1508名注册用户，平均每周收到5079次点击。在即将到来的资金周期中，我们建议在数据库中增加25个新的社区样本，其中包含5,500个家庭和大约34,650个人，并特别关注目前未在MMP样本中代表的移民输出国的社区。此外，我们建议在调查工具中增加一个基本健康问题模块，以提高其对数据用户和决策者的价值，并在用户可用的社区一级变量清单中增加选定的环境指标。公共卫生相关性：墨西哥移民到美国是美国人口动态最重要的贡献者之一。它通过有记录和无记录的移徙直接影响人口的增长和分布，但也通过其对死亡率和生育率的次生影响间接影响人口的增长和分布。该项目旨在为人口统计学家和政策制定者提供准确可靠的数据，了解墨西哥无证移民到美国的特点和行为。

DESCRIPTION (provided by applicant): Mexican immigration is probably the most controversial demographic issue facing policy makers and citizens in the United States today. The proposal seeks continued support for the Mexican Migration Project (MMP) to provide high-quality public use data on the characteristics and behavior of documented and undocumented Mexican migrants to the United States. To date the project has surveyed 118 communities, yielding a database of 128,940 persons enumerated in 19,726 households, which together contain 21,988 current and former migrants to the United States, 13,793 of whom were undocumented at the time of the survey. Data will be disseminated from the MMP website, which currently has 1,508 registered users and receives an average of 5,079 hits per week. In the coming funding cycle, we propose to add 25 new community samples containing 5,500 households and roughly 34,650 individuals to the database, paying special attention communities in migrant-sending states that are not currently represented in the MMP sample. In addition, we propose to add a module of basic health questions to the survey instrument to enhance its value to data users and policy makers, and to add selected environmental indicators to the list of community-level variables available to users. PUBLIC HEALTH RELEVANCE: Mexican migration to the United States is among the most important contributors to U.S. population dynamics. It influences the growth and distribution directly through documented and undocumented migration, but also indirectly through its secondary effects on mortality and fertility. This project seeks to provide demographers and policy makers with accurate and reliable data on the characteristics and behavior of undocumented Mexican migrants to the United States.
