You know the US cities most famous for their Irish-American population...but which US metropolitan areas have the most Irish immigrants? Guess the 25 metro areas with the highest Irish immigrant population as a proportion of total population.
All answers are metropolitan areas as defined by OMB, not city boundaries.
Proportion immigrant population is the estimated proportion of all residents, regardless of legal immigration or citizenship status, who were born in Ireland (not including Northern Ireland).
