"Living wage" means what a household needs for a dignified life, not just for bare subsistence.
If you need roommates because you can't afford an apartment on your own, you are poor by definition. That's probably the most universal definition of poverty that has ever existed. As long as there have been houses, the baseline household has had a housing unit of their own. Households that have to share housing with others have always been characterized as unusually poor, no matter the continent and the millennium.

Historically speaking this is incredibly wrong.
Nearly every culture evolved from some sort of shared communal longhouse to individual clan homes, to extended family homes. The idea of individual private rooms actually comes about explicitly from Manors in the late medieval ages. We really didn't see widespread individual homes until the industrial revolution. In places like the East, individual rooms were an import from the West.
Even in rare places where there were individual family homes (Ancient Egypt, for one). Privacy and individuality were just not concepts. Through the 1800s, you might have literally been sharing a bed with a stranger in a hotel.
There has also never, ever been a point in human history where living without some sort of roommate was common. Even in situations where you had lots of single workers, they almost always lived in bunkhouses or SROs.
You are missing the point.
This was about households rather than individuals and housing units instead of homes, and privacy is unrelated to the discussion. For example, longhouses typically had internal subdivisions that functioned as housing units. A household that cannot afford a baseline housing unit is unusually poor, regardless of its size.
In a developed country, the baseline housing unit most households can afford is typically an apartment or a house. Households that cannot afford one are unusually poor.
Someone who forms a single-person household and doesn't earn enough to rent an apartment is poor.
Single-person households are often poor, especially when the person is young. Living wage estimates for such households tend to be higher relative to typical wages than for larger households, as the idea of a living wage is largely about rising above poverty.
Not dignified. As you can live a dignified life for much less.
Thus my point. I don’t know what “livable wage” means with these numbers so it’s not very useful for discussion or planning or measurement.
