Census Linking Project: 1870-1900 Crosswalk

This crosswalk consists of individuals matched between the 1870 and 1900 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）收录了经匹配得到的美国1870年与1900年全人口普查个体数据。用户可在该对照表中选择本次匹配所采用的关联方法。本版本对照表包含三类方法生成的匹配关联：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。针对任意选定的关联方法，用户可将IPUMS公开提供的丰富个体及家庭层面变量与本对照表进行合并，从而构建可供分析的历史纵向数据集。
