I put the possibility of them massaging the data in some way at very remote. This study had a lot of eyeballs on it so risk of getting caught would be too high for them to entertain. Moreoever, the CoV grunts who do the actual work, like doing studies, seem both competent and of high integrity, and I don't think they'd be willing to betray their duty to the public and try to create a false impression of the unoccupancy rate.

I'm also puzzled by some of the numbers they post.

They point out that non-occupancy in many other housing types is incredibly low (0% - 1%).

They then estimate condo non-occupancy as ~ 12.5% (I'd say that's a big deal, since most new housing stock is in condo form).

And finally point out that short-term-non-occupancy (aka. two months of the 4 they're counting) sits at ~ 10% across all housing types - without breaking out the numbers for condos alone, or clarifying whether this short-term-non-occupancy is on top of the non-occupancy numbers above.

Clarification welcome.

They've been willfully ignorant to the numbers for some time. What is to say they aren't misinterpreting the data, fudging it, or ingoring factors like "more houses" or "more energy usage" while the number of people are dropping? This kind of thing goes on all the time here in Beijing, the only reliable way to determine vacancy is to count the lights that come on at night. All the other metrics, including energy consumption, are so gamed that they are useless.

They explain their methodology:

Does not look easily gameable, and the authors don't strike me as being disingenuous.

This piece is good also, to explain some of the limitations of the study:

So...I looked at their methodology, and I noticed one thing right off the bat:

They define a home as "unoccupied for the year" if its electricity usage is low during the non-heating months - aka. summer. This strikes me as flawed: summer is when you're most likely to be in Vancouver!

I think you are naïve if you believe that a government wouldn't fudge a study to support their best interests (best interests in this case being that most of their top campaign contributors are in the real estate business (1)). Let me give you an example of this happening recently in regards to the Vancouver real estate market.

The provincial government released a study on July 7th, stating that only 3% of real estate transactions across BC were from foreign buyers (2). Nobody believed this number, and plenty of people called foul (3). Every single person I talked to involved in the market laughed at those numbers (it is hard not to know someone involved in the market here). The government used these numbers as proof that foreign buyers were not an issue in BC.

Only 3 weeks later on July 26th, the exact same ministry in the government released new data that said that foreign buyers accounted for more than 10% of the value of real estate transactions in Metro Vancouver, which is by far the largest real estate market in BC (4). They used this as proof that foreign buyers were indeed a problem.

This is a prime example of the ridiculous politics that are at play here.

Also of note, if you look at (4), you will see that foreign buyers aren't just buying houses in the exclusive and expensive West Side Vancouver neighbourhoods. According to the data, Burnaby and Richmond, both had 18% foreign buyers.

The data fluctuates month to month. The data for both months was accurate. They may get political in how they present the data, but the way the collect and generate the data appears sound.
