摘要 墨西哥移民可能是政策面临的最具争议的人口问题 当今美国的制造商和公民。该提案寻求继续支持 墨西哥移民项目（MMP）提供有关特征的高质量公共使用数据 以及有证和无证墨西哥移民到美国的行为。迄今为止 该项目对 118 个社区进行了调查，形成了包含 128,940 人的数据库 19,726 个家庭，其中共有 21,988 名当前和以前的美国移民 州，其中 13,793 人在调查时没有证件。数据将被传播 来自MMP网站，目前有1,508名注册用户，平均收到5,079 每周点击次数。在接下来的资助周期中，我们建议添加25个新的社区样本 包含 5,500 个家庭和大约 34,650 个人的数据库，支付特殊费用 关注目前在 MMP 中没有代表的移民输出国社区 样品。此外，我们建议在调查中添加基本健康问题模块 工具，以提高其对数据用户和政策制定者的价值，并添加选定的 环境指标添加到用户可用的社区级变量列表中。

Abstract 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.
