Census Linking Project: 1870-1920 Crosswalk

This crosswalk consists of individuals matched between the 1870 and 1920 complete-count US Censuses. Within the crosswalk, users have the option to select the linking method with which these matches were created. This version of the crosswalk contains links made by the ABE-exact (conservative and standard) method, the ABE-NYSIIS (conservative and standard) method and the ABE-NYSIIS (conservative and standard) method where race is used as a matching variable. For any chosen method, users can merge into this crosswalk a wide set of individual- and household-level variables provided publicly by IPUMS, thereby creating a historical longitudinal dataset for analysis.本关联对照表（crosswalk）收录了经1870年与1920年美国全面人口普查交叉匹配得到的个体。使用者可在该关联对照表中选择用于生成此类匹配关系的匹配方法。本版本的关联对照表包含由以下三种匹配方法生成的关联结果：ABE-exact（保守标准型）方法、ABE-NYSIIS（保守标准型）方法，以及将种族作为匹配变量的ABE-NYSIIS（保守标准型）方法。针对任意选定的匹配方法，使用者均可将IPUMS公开提供的多组个体与家庭层面变量合并至该关联对照表中，从而构建可用于分析的历史纵向数据集。
