Fun with numbers (race to the bottom)

From The Evening Standard:

Fast-food takeaways will be banned from opening within 400 metres of schools in a bid to tackle the capital’s child obesity epidemic.

In addition, all new chicken, fish and chip and pizza outlets will have to sign up to minimum healthy food standards before getting planning permission. Sadiq Khan will announce the policy in his draft London Plan, the capital’s “planning bible”, due to be published later this week.

You know the answer is going to be 'zero', but let's do the numbers.

400 yds = 366 metres.

A circle with a radius of 366m has a surface area of 420,000 sq m = 0.42 sq km.

There are approx. 3,700 schools in Greater London (24,372 x 8 million/53 million).

3,700 schools x 0.42 sq km = 1,554 sq km.

Surface area of Greater London 1,569 sq km

I was a bit slow on the uptake here.

Dan Cookson beat us all to it, and even the BBC has pointed out that "In some parts of London, the only places that new fast food outlets would theoretically be allowed are in the middle of parks or the River Thames."
