The Healthy Ireland Survey is an interviewer-administered survey with interviews conducted on a face-to-face basis with individuals aged 15 and over. The initial wave of this survey involved 7,539 interviews. Fieldwork was conducted between November 2014 and August 2015.
In 2013, the Department of Health, in conjunction with Northern Ireland, commissioned the Sheffield Alcohol Research Group (SARG) at the University of Sheffield to conduct a health impact assessment as part of the process of developing a legislative basis for minimum unit pricing. The health impact assessment studied the impact of different minimum prices on a range of areas such as health, crime and likely economic impact. It also compared minimum unit pricing to other pricing policies.
