The number of persons with a dual Irish nationality almost doubled to 104,784 in Census 2016 from 55,905 in 2011. Persons may identify as having a dual nationality based on what citizenship they hold, where they were born, where they live or where their parents are from. In the case of dual Irish nationals 66,440 persons or 63.4 per cent were born abroad. However this ratio varied depending on which other nationality they identified as.
