Description
For persons in full count census files other than 1880, LINK1880 indicates if that person is linked to the 1880 census. Linked persons receive a common Historical Identification Key (HIK) value across all censuses in which they are identified. See the HIK variable for more information.
For persons in the 1880 census, a LINK1880 value of 1 indicates that they are linked to another census year, and in some cases multiple census years.
Any associated LINK variables are automatically included in an extract request for linked census pairs specified on the sample selection screen.
