To be worried about the low school intake this Sept?

[FurierTransform]

My daughter starts year R later this year
The school typically has an intake of circa 60 children, split between 2 classes. All pretty normal.
I've just been told that this coming year it is going to be nearer 40.
They are still running 2 classes.

On the surface it sounds great, smaller class sizes is what everyone wants right?
But i'm worried what the unseen impacts will be - on staffing levels, school funding etc, whether the teachers are equipped to capitalise on it as it seems abnormal, & the knock-on effect to the school for the next few years. Are any teachers or school staff reading who can comment?

Is this a nationwide demographic issue this year? was circa 2022 a low birth year?

According to ONS Births have fallen every year since 2015 except for a little blip in 2021. In 2015 there were 770,000 births and that has fallen to 653,000 in 2023, so a drop of over 120,000 a year. So yeah, that's what you're starting to see in school.
