Total Ancestries Reported
Includes the total number of ancestries reported and coded. If a person reported a multiple ancestry such as "German Danish," that response was counted twice in the tabulations--once in the German category and again in the Danish category. Also, if a person reported two different types of German ancestry, such as "Bavarian Hamburger", they would be counted twice in the German category on this type of table. Thus, each line of this table represents the number of reports for that ancestry type, not the number of people (although sometimes that number is the same). Likewise, the sum of the estimates in each of the rows in this type of presentation is not the total population but the total of all responses. The German line in this table is interpreted as "The number of times a German ancestry was reported."
