True, except for the fact that between household members is the highest transmission risk, so not having other household members would make a difference.

At the moment I'm thinking more in terms of social distancing than self-isolating. I won't be going in to work, but unless things change I wasn't planning on avoiding going out completely, so the benefits of a smaller town might come in to play. And I don't expect to be completely without social contact - Huddersfield is much better than most of the other non-London places I've worked for having nearby people who are accessible by much quieter trains/buses than London.
