Definitions

This page discusses the self-reported ancestry of the residents of Rock County. Respondents were not limited to one ancestry, so if a person reported both English and German, then they would be counted in both categories. Consequently, the sum of the counts over all the ancestries most often exceeds the total population of the entity. Asian and Hispanic ancestry is reported separately from European, Middle Eastern, and Subsaharan African ancestry. A full list of all possible categories is as follows:

  • European, Middle Eastern, and Subsaharan African Ancestries: Afghan, Albanian, Alsatian, American, Arab, Egyptian, Iraqi, Jordanian, Lebanese, Moroccan, Palestinian, Syrian, Arab, Other Arab, Armenian, Assyrian/Chaldean/Syriac, Australian, Austrian, Basque, Belgian, Brazilian, British, Bulgarian, Cajun, Canadian, Carpatho Rusyn, Celtic, Croatian, Cypriot, Czech, Czechoslovakian, Danish, Dutch, Eastern European, English, Estonian, European, Finnish, French, French Canadian, German, German Russian, Greek, Guyanese, Hungarian, Icelander, Iranian, Irish, Israeli, Italian, Latvian, Lithuanian, Luxemburger, Macedonian, Maltese, New Zealander, Northern European, Norwegian, Pennsylvania German, Polish, Portuguese, Romanian, Russian, Scandinavian, Scotch-Irish, Scottish, Serbian, Slavic, Slovak, Slovene, Soviet Union, Subsaharan African, Cape Verdean, Ethiopian, Ghanaian, Kenyan, Liberian, Nigerian, Senegalese, Sierra Leonean, Somali, South African, Sudanese, Ugandan, Zimbabwean, African, Other, Swedish, Swiss, Turkish, Ukrainian, Welsh, West Indian, Bahamian, Barbadian, Belizean, Bermudan, British West Indian, Dutch West Indian, Haitian, Jamaican, Trinidadian and Tobagonian, U.S. Virgin Islander, West Indian, Other West Indian, Yugoslavian, Other, and Unclassified
