Census Tree Links

The data sets in this repository allow users to link people among the U.S. decennial censuses, using the "histid" identifier. The census data sets users will need are indexed by Ancestry.com and are hosted by IPUMS at https://usa.ipums.org/usa-action/samples. Users will need to download the full-count census for each year and be sure to select the "histid" variable that is available under the Person/Historical Technical drop-down menu. As of 7/12/21, links are available between the 1900-1910, 1910-1920, and 1900-1920 censuses. A detailed account of how these links are created and a description of the data and its characteristics are available in the following article: Price, J., Buckles, K., Van Leeuwen, J., & Riley, I.

本仓库收录的数据集支持用户借助histid（histid）标识符，实现美国十年一次人口普查数据间的个体关联。用户所需的普查数据集由Ancestry.com编制索引，并由IPUMS托管于网址https://usa.ipums.org/usa-action/samples。用户需下载各年份的全量人口普查数据，并确保勾选"Person/Historical Technical"下拉菜单下可用的histid变量。截至2021年7月12日，可实现关联的普查年份组合包括1900-1910、1910-1920以及1900-1920。关于此类关联的构建方式、数据集本身及其特征的详细说明，可参阅下述学术论文：Price, J., Buckles, K., Van Leeuwen, J., & Riley, I.
