Is it a bad thing? People's life choices are their own. 29% seems like a fairly neutral number.
Considering there are both housing and loneliness crises going on, and that being lonely or socially isolated leads to an early death and radicalisation, I’d say it’s fair to categorise it as a bad thing, yes.
Sure, not every single one of those people living alone will be lonely, but I think it’s fair to deduce that many people who are lonely and isolated live alone.
