Recently the question around the amount of space taken up (exclusively) by single detached houses has show up on my Twitter feed citing that SFH take up 70%, 66%, and 57%, 56% (timestamp 3:50). I personally have thrown in 34% as a contender. And, just for the fun of it, by the end of this post I will have thrown 33% and 28% and my favorite, 81%, into the mix.
What’s going on, how can there be such a large range of estimates for what seems to be a simple question? The answer lies in the details of what exactly the question is asking, all of the above numbers are correct answers to one particular version of very similar questions.
The takeaway I think is most useful for general purposes:
35% of all households live on single family and duplex properties making up 81% of Vancouver's residential land, while the remaining 65% of households live on 19% of the residential land.
