Geographic patterns of ethnic groups in the United States.

The geographic distributions of 11 major ethnic groups within the United States, based on 1960 census data, are illustrated by computer-generated state economic area maps. The Scandinavian, German, and Russian ethnic groups were similarly concentrated primarily in the North Central region, while the Irish, Polish, Other East European, and South European groups were clustered predominantly in the Northeast. Other ethnic groups had patterns which were different from either of the above. These maps correspond to the atlases of mortality from cancer and other diseases.
