In 2023, 54% of the housing units in the US were single family detached, https://eyeonhousing.org/2024/10/owner-occupied-single-famil.... I guess some of those could not have yards, but that is pretty rare to not have any sort of yard in a single family detached home.
2/3 of home buyers have single family detached as their preferred housing, so more people want to live in that type of housing than currently do so.
