  • 18.8% of Reception children and 33.9% of Year 6 children in Barnet were overweight or very overweight in 2024/25.

  • Barnet has a significantly lower proportion of Reception and Year 6 children living with obesity compared to the London and England average.

  • As the deprivation of the area that students live in increases, the prevalence of overweight & very overweight also increases amongst Year 6 children in Barnet.
