This project is based on interviews with a national probability sample of U.S. journalists to document the tremendous changes that have occurred in journalism in the 21st century. More than a decade has passed since the last comprehensive survey of U.S. journalists was carried out in 2002. This 2013 survey of U.S. journalists updates these findings with new questions about the impact of social media in the newsroom and presents a look at the data on the demographics, working conditions, and professional values of 1,080 U.S. journalists who were interviewed online in the fall of 2013.
