Bar chart titled "Relatively Few Muslims Have Actually Visited Mecca" with subtitle "The number of pilgrims attending the hajj from 2004 to 2014." Each year's bar is split into two stacked segments: "Outside Saudi Arabia" (light green, bottom segment) and "Inside Saudi Arabia" (dark green, top segment). Y-axis: number of pilgrims, from 0 to 3,500,000 in steps of 500,000. X-axis years shown: 2004, 2006, 2008, 2010, 2012, 2014. Approximate total bar heights (outside + inside): 2004 about 2,150,000; 2006 about 2,380,000; 2008 about 2,400,000; 2010 about 2,800,000; 2012 about 3,150,000 (the tallest bar of the series); 2014 about 2,050,000 (a drop from 2012). Next to the bar chart, a world map shows the median percentage of Muslims in each region who say they have made the pilgrimage: Southern-Eastern Europe 3%, Central Asia 3%, Middle East-North Africa 17%, South Asia 6%, Southeast Asia 8%, Sub-Saharan Africa 13%.
