More than 16,000 people have taken part in Next Steps since it started.
As you were growing up, your parents or guardians may also have taken part in the study as well. So, in fact, nearly 30,000 people have been involved in Next Steps in one way or another.
At future surveys, we may want to talk to other important people in your life, such as your partner or children (if you have them). But it will be up to them to decide whether or not they want to take part.
