Irish Americans are citizens of the United States who can trace their ancestry to Ireland. A total of 36,278,332 Americans estimated at 11.9% of the total population reported Irish ancestry in the 2008 American Community Survey conducted by the U.S. Census Bureau. Roughly another 3.5 million (or about another 1.2% of Americans) identified more specifically with Scotch-Irish ancestry. The Irish diaspora population in the United States is roughly six times the modern population of Ireland. The only self-reported ancestral group larger than Irish Americans is German Americans. The Irish are widely dispersed in terms of geography, and demographics.
