The projections for pupil numbers up to 2030 were issued by the DfE this week.

At the same time the Office for National Statistics (ONS) looked at the likely size of + the school population  aged 5-15 National population projections – Office for National Statistics both have implications for the demand for teachers in England. This data can help determine how many teachers will be needed to staff schools and the attractiveness of teaching as a career.

The DfE concluded the following for the remainder of this decade;

State-funded nursery & primary schools

• The overall pupil population in these school types is projected to be 4,205,000 in 2030. This is 300,000 (6.7%) lower than the actual population in 2025 (4,505,000).
• The revised projection for 2028 of 4,319,000 pupils represents a 5.4% fall from 2024; this is 38,000 lower than the previous forecast, as last year’s projection showed a 4.5% fall over the same period.
• The nursery & primary population is therefore still projected to drop and is doing so at a faster rate than previously projected.

State-funded secondary schools

• The secondary school population is projected to be 3,135,000 in 2030. This is 97,000 lower than the actual school population reported in the 2025 school census of 3,232,000.
• The revised projection for 2028 of 3,208,000 secondary pupils represents a 0.8% fall from 2024, and is 55,000 (1.7%) lower than last year’s projections which reverses the previously projected 0.9% increase over the same period. 
• The pattern of change in the secondary school population seems to indicate that it plateaued between 2024 and 2025, will remain at a similar level until 2026, and is then projected to start declining slowly. This suggested plateau is earlier than the peak in 2026 projected last year but will be subject to change if pupil numbers bounce back, fluctuate, or continue to plateau in future years.
• The actual number of secondary school pupils in 2025 fell slightly as more pupils moved out of the secondary phase than moved in. Changing historical birth rates and trends in net migration are likely driving factors. National pupil projections, Reporting year 2025 – Explore education statistics – GOV.UK 

According to the ONS projections, there are expected to be fewer children in the UK by the middle of both 2032 and 2047, compared with the middle of 2022. The ONS have based this on a view that the assumed fertility rates in the 2020s and 2030s will be even lower than those around 2001, when UK fertility reached a record low.

By mid-2032, the number of children (those aged from 0 to 15 years) is projected by the ONS to have decreased by 797,000 (a fall of 6.4%), from 12.4 million to 11.6 million. By mid-2047, the number of children is projected to remain around the mid-2032 levels. Of course, if the birth rate changes, these numbers could be either too high or an underestimate. Either way planners are no expecting the need for more teachers due to changes in the birth rate.

However, these numbers are just assumptions, and don’t take into account other changes in the numbers in the 0-15 age groups resulting from any net balance once both emigration and immigration have been taken into account.

Other factors, such as the departure rate from teaching, due either to the popularity of teaching or the availability of alternative employment opportunities, as well as the age-profile of the profession and the number of teachers retiring can affect the demand for teachers. Policy changes concerning how children are taught can also affect the demand for teachers. How will AI and attitudes to issues such as home schooling are two imponderables that might affect the demand for teachers.

These days, as well as the traditional modelling, the DfE has access to up to the minute data on vacancy rates for teachers, and how posts are filled. This new data, allied to more traditional methods of estimating the demand for teachers, should help to ensure teacher unemployment can be kept to a minimum. After all, there is little point in spending money training teachers only for them to be both burdened with debt and unable to find a teaching post.
