What is a birth cohort study?
A birth cohort study is one that follows a group of people that were born at a similar date or period of time – be it a day, month, year or decade, for instance. It follows these people throughout their lives, and collects data from them at particular ages. By following the same people over time, these studies are able to show how and why people change as they get older. Child of the New Century is a birth cohort study following people born at the turn of the new millennium.
