With an estimated 13 million pints of Guinness consumed around the world every year (enough to fill two and a half Olympic-sized swimming pools), St. Patrick's Day is a pretty big deal. Even though business booms on the Emerald Isle on March 17 every year, nowhere likes to don the green, have a party and spend big bucks like the USA. 56.1 percent of Americans, some 139 million people in total, are going to embrace their inner Irishness and celebrate St. Patrick's Day this year. On average, each person is expected to spend $37.92, up from last year's $35.37. Take a look at the infographic below where you can see some of the key numbers behind America's favorite imported holiday.
