National Readership Survey

The National Readership Survey is a joint venture company in the UK between the Institute of Practitioners in Advertising (IPA), the Newspaper Publishers Association (NPA) and the Periodical Publishers Association (PPA). It provides audience research for print advertising trading in the UK. The survey covers over 250 of Britain's major newspapers and magazines, showing the size and nature of the audiences they achieve. It classifies audiences in a number of ways, one of which is the NRS social grade.
