Part 5: Deprivation (based on postcode of the school)
For NCMP, we provide deprivation data based on both where the child lives and where the child attends school. Deprivation based on where the child lives is more accurate since sometimes children attend schools in areas with different relative deprivation compared to where they live. Part 4 of the report uses the deprivation decile of the child postcode as the main analysis of the current year, and changes since 2013/14.
Part 5 uses the deprivation decile of the school and gives time series from 2006/07. The NCMP data collection was most affected by the Covid-19 pandemic in 2020/21 see Data Quality Statement Impact of the Covid-19 pandemic on the NCMP. The 2019/20 NCMP collection was incomplete as no measurements were taken after March 2020, when schools were closed as part of the response to the COVID-19 pandemic. Data quality work on the 2019/20 data indicated that the deprivation data presented in the gap analyses is comparable with earlier years and suitable to use as a pre-Covid-19 pandemic reference point.
The deprivation gap is defined as the difference in the prevalence figures between those children in the most deprived decile and least deprived decile.
Reception – deprivation gap for obesity
Among reception children attending schools in the most deprived areas, the prevalence of obesity increased from 12.2% in 2006/07 to 19.7% in 2020/21, the year most affected by the Covid-19 pandemic. This decreased to 12.2% in 2022/23, which is lower than 13.0% in 2019/20 (pre-pandemic).
Among reception children attending schools in the least deprived areas, the prevalence of obesity increased from 7.7% in 2006/07 to 9.1% in 2020/21, the year most affected by the Covid-19 pandemic. This decreased to 6.3% in 2022/23, which is lower than 2019/20 (6.7%, pre-pandemic).
Over time, between 2006/07 and 2018/19, the deprivation gap for reception children attending schools in the most and least deprived areas increased, due to the prevalence of obesity increasing in the most deprived areas and reducing the least deprived areas. In 2022/23 the deprivation gap is 5.9 percentage points, closer than in recent years.
For children attending schools in the most deprived areas, the prevalence of obesity among girls increased from 11.3% in 2006/07 to 11.9% in 2022/23. The prevalence of obesity among boys decreased from 13.0% in 2006/07 to 12.4% in 2022/23.
For children attending schools in the least deprived areas, the prevalence of obesity decreased among girls from 7.0% in 2006/07 to 5.9% in 2022/23 and decreased for boys from 8.3% in 2006/07 to 6.6% in 2022/23.
Overall, the increase in the deprivation gap over time was similar for boys and girls.

For children attending schools in the least deprived areas, the prevalence of obesity increased from 1.5% in 2006/07 to 2.2% in 2020/21, the year most affected by the Covid-19 pandemic. This decreased to 1.3% in 2022/23, which is similar to 2019/20 when it was 1.3% (pre-pandemic).
Between 2006/07 and 2019/20, the deprivation gap for children attending schools in the most and least deprived areas increased from 2.1 percentage points to 2.6 percentage points. It then increased in 2020/21 and fell in 2022/23 to 2.5 percentage points - a level more similar to earlier years.
For children attending schools in the most deprived areas, the prevalence of severe obesity among boys increased from 4.0% in 2006/07 to 8.1% in 2020/21, the year most affected by Covid-19 pandemic. This then decreased to 4.0% in 2022/23 which is similar to 4.0% in 2019/20 (pre-pandemic). The prevalence of severe obesity among girls increased from 3.2% in 2006/07 to 6.6% in 2020/21, the main year of Covid-19 pandemic. This then decreased to 3.6% in 2022/23, which is similar to 3.8% in 2019/20 (pre-pandemic).
For children attending schools in the least deprived areas, the prevalence of severe obesity among boys increased from 1.7% in 2006/07 to 2.6% in 2020/21, the year most affected by Covid-19 pandemic. This then decreased to 1.4% in 2022/23 which is similar to 1.3% in 2019/20 (pre-pandemic). The prevalence of severe obesity among girls increased from 1.2% in 2006/07 to 1.8% in 2020/21, the main year of Covid-19 pandemic. This then decreased to 1.2% in 2022/23, which is similar to 1.3% in 2019/20 (pre-pandemic).
The deprivation gap in 2022/23 was similar for boys and girls.
Year 6 – deprivation gap for obesity
For children attending schools in the most deprived areas, the prevalence of obesity increased from 21.5% in 2006/07 to 32.1% in 2020/21, the year most affected by the Covid-19 pandemic. This decreased to 29.9% in 2022/23, but is still higher than 2019/20 (pre-pandemic) when it was 27.2%.
