The Active Lives Adult Survey is sent out to a randomly selected sample of households across England.
If you've received a request to answer the Active Lives Adult Survey, you'll have received a letter like this.
Your responses are really valuable as they help to provide an in-depth picture of how many people take part in sport and physical activity by demographic group, location and activity type.
As a thank you, we’ll give you a £5 gift voucher which can be redeemed from a range of retailers including department stores, fashion stores and restaurants.
To answer the survey, just go to www.activelivessurvey.org and type in one of the passwords on your invitation letter.
If you have any further questions about the survey, or how to complete it, please email email@example.com.
