How are local lockdowns decided?

[Mykidsthinkimclueless]

I have tried having a look online to see but can't work it out. I have avoided reading lots of Covid news for a while but I keep an eye on local figures. The rate in my city is quite low but the % week on change is over 100%. On the "on the rise" map the guardian displays for we are shown as red.

Is the main impact of local lockdowns the restrictions on visiting homes/meeting up indoors?

Map. Dartboard. Blindfold.

Its worked out on the rate per 100,000.
I think the restrictions will be linked to how they think the virus is spreading

So there aren't set figures that trigger it.

Ah ok. I really am out of touch.

It depends how important the area where you live is.
So if you live in somewhere like London it wont go into a local lockdown.
If you live in a small isolated village even if your rate is none existent unfortunately you will have to go into a lockdown.
