Potential advertisers are told instead of a 2003 Mediamark poll commissioned by NPR. Compared to the general public, NPR listeners are 152 percent more likely to own a home valued at $500,000 or more; 194 percent more likely to travel to France; and 326 percent more likely to read the “New Yorker.”
