Hard to argue with this maths…
It’s one of the things about economists – sometimes their job is to just point out the obvious.
Old ABC economic grey-beard Alan Kohler was dropping some truth-bombs the other day when he unpacked what’s going on with the housing crisis.
I’d love to say that this is some complex rocket-science kind of stuff. But it’s kindergarten-level math.
That doesn’t make it wrong though.
So first up, he looked at what’s happening to supply. As he rightly notes, “We know that dwelling approvals have been in trend decline for 10 years”.

Yep, and even that’s a pig with lipstick on it. That’s just the raw numbers. Given the population is trending upwards, that series should be trending upwards as well. But it’s not.
Which is what makes it such an abysmal result.
Anyway, that’s the supply side.
On the demand side – the old bedfellow of supply – Kohler notes things are trending the other way:
“We also know that population growth has been climbing for 20 years driven by a doubling and then tripling of migration”.

Yep, John Howard opened the gates, and every government since has enjoyed the sugar hit of stronger immigration.
So supply trending down, demand trending up. And that’s why the shortage gets worse every year.
If you’ve been following my work for a while none of this will be new to you.
But what Kohler did was look at it at the monthly level to try get a sense of just how quickly things are going to poop.
These back-of-the-envelope calculations are a little alarming.
On the demand side, Kohler estimates that net overseas migration, plus natural increase, created a population demand of 57,000. Divide this number by 2.5 – the average occupancy rate – and this gives demand for an additional 23,000 dwellings.

On the supply side, there were 10,903 dwellings approved for construction in January 2024, assuming it takes one year to build a home.
(That’s actually generous, since we know not all approvals go on to be completions, and some approvals are for knock down and rebuilds.)
Anyway, when you put these two together, Kohler estimates that there was a housing shortfall of around 12,000 dwellings in January 2025. “Demand was more than twice supply”, says Kohler.

That’s 12,000 homes short, in a single month!
If that’s a typical month, and I reckon it probably is, then the housing shortage in Australia is getting worse at a pace of 12,000 homes a month!
Every month.
In a year, that’s 144,000 homes.
This is supposed to be going the other way. We should be building more homes than we need each month if we want to make the housing shortage better.
But we’re not. We’re going the other way. At an alarming clip!
This is why prices go higher, year after year after year.
It’s not rocket science.
