The latest edition of this report (2025), produced in partnership with research agency Savanta, uses artificial intelligence modelling and insights from children’s polling to project the consequences of current inactivity trends for the children of the Class of 2035. It paints a concerning picture of a nation at a crossroads, with inactivity rising and wellbeing declining.

By 2035, if current trends continue:

• Almost half (48%) of children will spend three hours or more on screens for entertainment each day, up from 34% in 2025.
• More than a third (34%) will fail to be active for even 30 minutes a day, well short of the UK’s Chief Medical Officers’ guidance of 60 active minutes.
• Annual Type 2 diabetes diagnoses in children will double, reaching 500 new cases each year.
• Obesity rates among 10-11 year olds will surge to 24% by 2035, with more than 180,000 children classified as clinically obese, up from 22% in 2025.
• Schools will see declining attendance, engagement, and belonging among the least active pupils.
