Other data sources

The Health Survey for England also collects data on childhood obesity covering all children aged 2-15.  However as it is a sample of about 2,000 children in England, the estimates are less precise than those for NCMP for the reception year and year 6 children.

The Office for Health Improvement and Disparities (OHID) in the Department of Health and Social Care (formerly Public Health England) conduct additional analyses on the NCMP data and produce a range of tools and reports.


The NCMP covers children attending schools in England only. Other countries in the UK publish similar reports and these are signposted below. There are differences in methods of collection and ages of the children measured which must be taken into consideration when comparing data across the UK countries.

Links to the latest reports from each country are:
