This is the seventh Healthy Ireland Survey and adds to the data collected in the previous surveys from 2015 - 2020.

A representative sample of approximately 7,400 people, aged 15 and older, living in Ireland was interviewed between October 2020 and June 2021.

The survey gives an up-to-date picture of the health of the nation and reports on many lifestyle behaviours, such as smoking, alcohol consumption, diet, mental health and health services.
