"There are 70 million people around the world who claim Irish ancestry. What shaped and made the great Irish emigration?"
"From 1700 to the present, fully ten million Irish men, women and children left Ireland and settled abroad. Remarkably, this figure is more than twice the population of the Republic of Ireland today (4.8 million). It exceeds the population of the island of Ireland, north and south (6.6 million). And it is greater than the population of Ireland at its peak in 1845, on the eve of the Famine (8.5 million). Some 70 million people worldwide claim Irish descent, more than half of them in the United States, where Irish is the second most common ancestry after German."
