Please provide any information regarding millennial's, those born between 1981/1999, and their usage of social media and how this may influence their adoption of healthy living.

Thank you for your request.
We do not hold the information that you have requested. However, our Internet Access Households and Individuals statistical bulletin contains some information on adults' use of the internet for social media, although we don't refer to 'millennials' as such. The statistics in this bulletin are broken down by age groups in years, of 16-24, 25-34, 35-44, 45-54, 55-64 and 65+.
Table 13 of the 2017 bulletin contains estimates of the proportions of adults who have used social media (not those who have social media accounts). This table also contains estimates of the proportions of adults using the internet to look for health related information, but we don't have further information on the ways they have used the internet to do this.
