A new economic study paints a picture of a thriving Twin Cities art scene. University of Minnesota researchers say artists - and in particular dancers and writers - comprise more of the workforce here than in other similar-sized metropolitan areas. And the concentration of artists is growing fast. It's on pace with Seattle and Albuquerque and growing faster than Chicago, Atlanta and Dallas. Ann Markeson is director of the Project on Regional and Industrial Economics at the Humphrey Institute. She says that artists are highly enreprenurial and represent a hidden arts dividend for the economy.
