Absent anything else, of course most people prefer to live in single-family homes (SFH). But that's not the question most people have to face in reality, because SFH have other trade-offs that that survey completely ignored, including:

- significantly higher cost (absent widespread R1 zoning, which drives the cost of apartments up),

- locations in the middle of desolate suburbia,

- dead neighbourhoods because almost no one lives there,

- very few nearby stores and restaurants,

- no or limited public transit because it costs far too much to run in sprawling suburbia,

- utter dependence on personal automobiles, and the complete lack of independence for children, young adults, and other non-driving members of society,

- the necessity of maintaining the grounds of your own personal park,

- poorly maintained or missing public infrastructure because everything is so spread out,

- having to endure endless traffic because of your 1hr commute to work,

and I could go on.

Given the above, if apartment living wasn't so heavily restricted by law, so many more people would choose to live in them rather than SFH. You only need to look at cities like Montreal or entire countries like the Netherlands to see that this is true.

In Montreal, housing is still cheap and most people live in multiplexes (walk-up two-to-four storey buildings with private front doors and small back yards) and live very close to where they work, but there are still a lot of different styles of SFH that people can choose to live in if they want, and many do. Again, look at the video I linked above for examples.
