Dear AP Stat students,

Our city is becoming more popular than ever!

Tourism is vital to the economy of Greater Philadelphia. To be exact, in 2010 tourism was responsible for 8.7 billion dollars in economic impact on the City of Brotherly Love. Also, it directly sustains 65,000 jobs for Philadelphians. It generated 273 million dollars in local taxes too. For all of these reasons and more, tracking these statistics is imperative for our region.
