#IsThisABigNumber
Why learn mental arithmetic? Well so you can do #IsThisABigNumber and #IsThisFair in your head *whilst* listening to advertising and propaganda. That gives you power.

A reminder that those asking #IsThisABigNumber about populations can often find the answer via our wonderful Office for National Statistics. And everyone should be asking #IsThisABigNumber?

#IsThisABigNumber back of envelope estimate adults in UK ~50million so ~£200/adult, less than spent on annual servicing of cars.

The border is 5,525 miles long. So that's one trooper for every half-mile.
8-hour shifts means one trooper for every 1½ miles.
Add in vacation time, etc, and... well, you get the picture.

#IsThisABigNumber is always a good response!

#IsThisABigNumber: 1 bottle a week for 20 years ~ 1000 so that's "several" bottles a week for 20 years.... er probably doesn't need to buy any more. Ever.

1600sq km. So a bit more than a 1km strip the length of the country, or a 4km x 4km square in every county. Good #IsThisABigNumber question!

Ah, a classic #IsThisABigNumber? What are the current figures it is increasing from? What is the exponent? For how long? We talking grains of rice on a chess board or "twice as much next year"?
🙄
Unhelpfully for UK farmers - and the Prime Minister - the USA says at the ongoing press conference that the trade deal will "exponentially increase export of US beef" to the UK.

8 sites doesn't sound a huge number. What is the usual turnover? #IsThisABigNumber?

I do enjoy an instinctive #IsThisABigNumber response to a headline.

#IsThisABigNumber Assume 50 million people in the UK have been to London at least once in the last 20 years, got an Oyster Card with £5 spare and left it in the drawer for next time. That's £0.25 billion.
Bit surprised it's not more tbh.

Imagine if all the news programmes had someone interrupt every 2 minutes to say "ahem, #IsThisABigNumber? No? Shall we move on?"

OK, it seems appropriate to ask #IsThisABigNumber ? Pop Scotland 5.5 million, say <1/55 per year group for ease, so <100,000 per year, so >5% extra people learning to ask #IsThisABigNumber ...that sounds like a useful contribution. Or say, 2k in Glasgow and 2k in Edinburgh + a few more. Good job👏

That's handy for #IsThisABigNumber though. Assuming this missing number is a million, that's a solar panel for every Year 7. That sounds a useful amount!

Inevitably, this being social media, eventually someone says you should make your own yoghurt. 🤦‍♀️ What with the #IsThisABigNumber stories, reposts of racism on X (You Must See the stuff you came here to avoid!!!) and the people who don't know their AI from their elbow it's all a bit much.

#IsThisABigNumber?

The current number of asylum seekers in hotels (~30k, BBC news) is less than the number of students at Manchester University alone.
Too many, for those individuals living in limbo. But nationally, not a lot.

Also (self-motivated here), anyone know about £2.4billion for flood infrastructure #isthisabignumber? It sounds pretty big, especially over 2 years (£200/adult/year) but how does it compare to normal?

And this is not the least reason I'm loving the portrayal of Kate Lethbridge-Stewart. She asks "What's the scale?" 😍
But #IsThisABigNumber? Let's help them out with the answer...

A mistake that big should have triggered his #IsThisABigNumber intuition. At 20% of payroll it is so *obviously* wrong he should have thought to check, or if just a typo correct as soon as pointed out. Not everyone is capable of that, but nether is everyone is capable of doing the job.

A lot of news stories are "2000 people did this!!!!" or "$$$ spent on!!!" and the first question to ask is #IsThisABigNumber? Usually when you divide by population it looks far less exciting.

#IsThisABigNumber? There are a lot of small shops. In the UK almost all have bollards outside to stop them being deliberately rammed by vehicles, which became a fashionable way to break in about 20 years ago.

#IsThisABigNumber... about 1 in 500 people in the UK are injured on the roads in a year (gov.uk, below). Presumably there are more crashes that don't result in injuries, including minor ones that aren't recorded. So 1 in 2000 vehicles sounds right order of magnitude?
