Abstract

I introduce and analyze the Mexican Border Crossing Records (MBCRs), an unexplored data source that records aliens crossing the Mexico-US land border at diverse locations from 1903 to 1955. The MBCRs identify immigrants and report rich demographic, geographic and socioeconomic information at the individual level. These micro data have the potential to support cliometric research, which is scarce for the Mexico-US migration, especially for the beginnings of the flow (1884-1910). My analysis of the MBCRs suggests that previous literature may have inaccurately described the origin of the first Mexican immigrants. My findings diverge from historical scholarship because the micro data capture the geographic composition of the flow at the local level and across nine entrance ports, allowing me to characterize with precision the migration patterns during the 1900s. Overall, the micro data reported in the MBCRs offer the opportunity to address topics that concern the economics of migration in the past and present.

摘要

我介绍并分析了墨西哥边境过境记录（MBCR），这是一个未经探索的数据源，记录了1903年至1955年在不同地点穿越墨西哥-美国陆地边界的外国人。MBCR可以识别移民，并在该处报告丰富的人口，地理和社会经济信息。个人水平。这些微观数据具有支持气候学研究的潜力，这对于墨西哥至美国的迁徙来说是稀缺的，特别是对于流量的开始（1884-1910）。我对MBCR的分析表明，以前的文献可能不准确地描述了第一批墨西哥移民的来历。我的发现与历史学者有所不同，因为微观数据捕获了本地和9个入口港口的流量的地理组成，使我能够精确地描述1900年代的迁移模式。总体而言，MBCR中报告的微观数据提供了解决与过去和现在的移民经济学有关的主题的机会。
