This is a long standing question for me, but I had thought I knew the answer.
Question: When Citing a Census Record, should the Citation be a Per Person Citation or a Household Citation ?
Looking that EvidenceExplained and the Ancestry QuickSheet, the examples were not household based, it appeared to be for each individual.
For me the issue came to light when the Interface between my genealogy database management software and Ancestry.com changed. I have always done the Citation by Household, which included the Line Numbers as part of the citation, and the Head of Household's name, followed by "household".
In the past, I have one record, a census record page(s) for example, with links to many people, and many facts or events.
Ancestry changed it to be One Record, One Person, many facts or events.
I am looking at a 1910 Federal Census record, where there are 6 people in the household, plus 4 "parents of" people, with a total of 38 facts or events.
The Household method that I have been doing, would have had 1 Citation, linked to those 10 people, and 38 facts.
So, before I "fix" the citation(s) for this record, I thought I would ask for that clarification.
