I’ve posted blogs dealing with America’s ethnic map before. However, it’s worth doing again. The following excerpt is from an article in the April 18, 2014 edition of the online Washington Post:
The history of European colonization of the Americas is still evident today in most of the United States. This very cool map shows which ancestries make up the largest population in each of the country’s 3,144 counties.
Some highlights to note: The Irish really do run Boston. People of Irish ancestry make up the largest contingent of counties in Massachusetts, and in parts of Rhode Island, southern New Hampshire and eastern New York. The only counties outside the Northeast where the Irish make up the biggest share of the population are in southern Oregon.
