Erin go Braugh

Happy Saint Patrick’s Day! In searching out where the Irish and their descendents live in the United States I came across a good number of maps. The first I found was from an article in Forbes listing the cities in the United States with highest density of Irish.  Boston was the highest with 20.4%.  More fun facts about the Irish diaspora is that Irish-Americans are at least 5% of the popirish Nationals2ulation in most counties across the U.S., and 10% or more in most of New England, New York state, New Jersey, eastern Pennsylvania, and other smaller counties across the country. At the other extreme, Miami is just 1% Irish.  What I really wanted was a map that would allow a user to click on a county and see what percentage of the population is of Irish ancestry. I got close with a map posted today by the US Census that showed Irish in the United States using figures from 2009 to 2013.   The Census map is pretty but it didn’t allow me to drill down as far as I wanted.

I found an interactive map, Measuring the U.S. Melting Pot, that offered me a means of comparing the ethnicity of various populations in the United States.  You can compare the number of Swedes to Norwegians in Minnesota, the number of Irish to Italians in New York City, the Irish to the Germans in Iowa.  Another map of interest is, Mapping the Emerald Isle: a geo-genealogy of cartogram irishIrish surnames, where you can search a a surname and find where folk of that name lived in  which Irish counties, both the Republic and the North,  according to the 1890 census.  I also found a cartogram, posted by Jerry Soloman from the University of Georgia,  of the percent ofIrish ancestry by county.  It still wasn’t interactive, but it was a fascinating map.  Cartograms distort the area of geographic features to reflect the values of an underlying variable, in the map to the  right, it shows the percentage of those claiming Irish descent.  The cartogram at the bottom shows shows those claiming Irish ancestry with an emphasis large urban areas. (I particularly like it because it kind of resembles a whale.)  And whether you can claim any Irish blood, most all of us live in a county were someone can. Sláinte!
