Public Use Data on Mexican Immigration

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。该提案寻求对墨西哥移民项目（MMP）的持续支持，以提供关于有证件和无证件的墨西哥移民到美国的特征和行为的高质量公共使用数据。到目前为止，该项目调查了118个社区，产生了一个数据库，其中包括19 726个家庭中的128 940人，总共有21 988名目前和以前到美国的移民，其中13 793人在调查时没有证件。数据将从小额供资和微型企业方案网站传播，该网站目前有1 508个注册用户，平均每周点击5 079次。在下一个供资周期中，我们建议在数据库中增加25个新的社区样本，其中包括5，500个家庭和大约34，650个个人，特别注意移民输出州的社区，这些社区目前没有出现在MMP样本中。此外，我们提议在调查工具中增加一个基本健康问题单元，以提高其对数据使用者和决策者的价值，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的最重要贡献者之一。它通过有证件和无证件的移徙直接影响人口的增长和分布，但也通过对死亡率和生育率的次级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关于无证墨西哥移民到美国的特征和行为的准确和可靠的数据。

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.
