When we examined 10 of the largest data brokers in the country, we found them advertising data on hundreds of millions of Americans: their sensitive demographic characteristics, their political preferences and beliefs, and their whereabouts and real-time locations, as well as data on first responders, healthcare workers, students, government employees, and current and former members of the U.S. military. Unlike the Vermont and California laws, however, which exempt many kinds of companies from classification as a “data broker,” Delaware’s bill encompasses a range of businesses selling or licensing individuals’ data.
