First Ancestry Reported
Includes the first response of all people who reported at least one codeable entry. For example, in this type of table, the count for German would include all those who reported only German and those who reported German first and then some other group. The German line of this table could be interpreted as "The number of times German was listed as the first, or only, ancestry."
