Polk County travel expenditures were at $1.63 billion in 2011, while Dallas County brought in $157 million, bringing the total expenditures for Greater Des Moines to $1.8 billion, a 12.5% percent increase over 2010. Total expenditures in the state of Iowa were $7.2 billion.
Greater Des Moines travel expenditures were driven, in part, by conventions and sports events secured by the Greater Des Moines Convention and Visitors Bureau, the parent organization of the Des Moines Area Sports Commission. In 2011, these events included the NCAA Track & Field Outdoor Championships, World Pork Expo and the American Volkssport Convention.
