Why are Irish Pubs so popular around the world?

There are over 7000 Irish Pubs outside of Ireland in over 53 countries from Mongolia to Iraq, Australia to Canada, Bolivia to Russia. Irish pubs have become popular around the world for a variety of reasons. One major factor is the popular cultural identity and heritage associated with Ireland and its people. Irish establishments have a warm and welcoming atmosphere, with a focus on community and conviviality, which appeals to people of all backgrounds. 

The enormous spread of 80 million people around the world who claim Irish heritage is another major contributing factor to the success of Irish pubs. From New York to Sydney, 'Irish' bars sell stout and Irish whiskey to people whose ancestry may be many generations removed from Ireland, and yet who seek in them an affinity with a country they may never have seen. The popularity of Irish food and drink also contribute to the worldwide appeal of Irish pubs.
