资源简介：
The Census Tree is the largest-ever database of record links among the
historical U.S. censuses, with over 700 million links for people living
in the United States between 1850 and 1940. These links allow
researchers to construct a longitudinal dataset that is highly
representative of the population, and that includes women, Black
Americans, and other under-represented populations at unprecedented
rates. Each .csv file consists of a crosswalk between the two years
indicated in the filename, using the IPUMS histids. For more
information, consult the included Read Me file, and visit https://censustree.org.<br>
人口普查树（Census Tree）是迄今为止规模最大的美国历史人口普查记录关联数据库，涵盖1850年至1940年间居住在美国的民众间超过7亿条关联记录。此类关联关系可帮助研究人员构建具备高度人群代表性的纵向数据集，且以空前的比例纳入女性、非裔美国人及其他代表性不足的群体。所有.csv文件均基于IPUMS历史ID（IPUMS histids），构建了文件名所标注的两个年份之间的交叉对照表。如需了解更多信息，请参阅附带的Read Me文件，并访问https://censustree.org。
