I’m in the north and affected by local lockdowns. My council has been in and out of it!
There’s the socio-economic mix up here. You can have pretty little villages with no cases miles from wards with multiple cases, but everyone gets tarred with t’same brush. It feels like postcode punishment for choosing to live in the wrong area. You can follow the (inconsistent) rules strictly and still get locked down.
Another poster mentioned that northerners often live near family and visit them as opposed to Londoners being more isolated due to an incomer mix, there may be something in that.
Having briefly lived in the SE, one thing I noticed is that due to the high costs of living, there wasn’t much of a pub culture, and people didn’t really eat out much. Whereas in the northern towns and cities living costs are much cheaper so more disposal income= more of an eating and drinking out culture, busy bars, lots of mixing etc.
Finally, there are a lot of small businesses up here who have a different attitude about WFH to the big employers. Some small businesses don’t want employees to work from home. My friends and I who work for small businesses have all had to return to the office, whilst those with large employers are allowed to WFH. That’s before you even start looking at the businesses like factories where WFH is impossible.
