<p>The National Child Measurement Programme (NCMP) collects data on the height and
weight status of children aged between four and five years old in reception grade
and between 10 and 11 years old in year six. NHS England publishes data on the average
height of children in reception and year six by sex and academic year. The data on
average height is not available in the requested format for each ethnic group, nor
is data on the number of state school pupils in reception year and year six by ethnic
group and academic year published in the requested format.</p><p>The following table
shows the data on national average height from the NCMP since the programme began
in 2006/07 up to 2021/22, the period for which the most recent data is available:</p><p>

NCMP</p><p>Notes:</p><ol><li>Analysis of the NCMP data in the first three years show
lower participation rates in the programme and suggested selective optout of children
with a higher body mass index for age. It is possible that average height figures
for year six for 2006/07 to 2008/09 could have been affected by this lower participation
in the measurement programme.<p> </p></li><li>Some of the variation in height across
all NCMP years may be due to variation over time in average age of children when measured.
In 2019/20, children were only measured up to March 2020 so the average age of children
and therefore mean height was lower than other collection years. In 2020/21 the NCMP
data collection did not start until April 2021 so the average age and therefore average
height was higher than other collection years.<p> </p></li><li>The 2020/21 NCMP only
collected around 20% of the usual sample. The sample was found not to be fully representative
and therefore weighting was used in most NCMP publications to make the data comparable
to other NCMP collection years. However, NHS England did not apply the weighting to
the 2020/21 figures in the table above. When combined with the higher average age
of the sample in 2020/21 it implies that data for 2020/21 cannot be reliably compared
to the rest of the time series.</li></ol>
