Data on housing supply in Australia’s capital shows, while its increasing in areas with lots of jobs, the house prices are too high for those who might want to move for work, writes…
Australia’s capital cities are getting more and more units, that are largely concentrated and come with a hefty price tag, a new report shows.
And while these areas also have lots of jobs, the high price for houses means many on low incomes won’t be able to access that employment.
Between 2006 and 2014, more than 50% of new units were built in the 20% of local government areas with the highest number of jobs.
When compared internationally, it would seem that Australian housing supply has not been as weak as is widely believed.
However, the report points to some stark differences in housing supply patterns, emerging across Australia’s capital cities.
In Sydney, Perth and Brisbane, new housing supply has lagged slightly behind population growth.
In the other capital cities, housing supply actually outpaced population growth between 2006 and 2014.
Housing supply and house prices
The issue of housing affordability has traditionally been pitched in terms of supply failing to keep pace with growing demand, and house prices rising in response to the imbalance.
Yet, house price inflation has surged even in metropolitan areas where housing supply exceeds population growth.
The evidence suggests a complex relationship between supply, population growth and price that is shaped by both supply and demand-side factors.
As prices and rents rise, housing costs continue to eat up larger shares of household incomes, particularly in moderate and low-income groups.
The study shows 80% of new unit approvals were located in the top 20% of local government areas with the highest unit prices.
This is while 80% of new house approvals were in the top 40% of local government areas with the highest house prices.
There is very little new supply in areas where house prices are lower, where households on low to moderate incomes can afford to live.
Affordable housing, cities and productivity
The lack of affordable housing in the vicinity of employment centres can pose threats to the productivity of our cities.
If suburban residents are forced into longer commutes to access employment in the CBD, it can reduce productivity.
A potential consequence is that low-paid workers are deterred from seeking jobs in CBDs.
This would then cause certain skills to become unavailable, and businesses to be less efficient, because they cannot quickly fill vacancies with suitable applicants.
Our data shows new units have grown by 30% in areas which have the most jobs, between 2005-06 and 2013-14.
In contrast to this new units have only grown by 2.5% in areas with less jobs.
It would appear that unit approvals are concentrated in areas with abundant job opportunities.
So productivity could improve, as congestion eases, and commute times lowered, if (and it’s a big if) these dwellings were affordable to those wishing to take advantage of these job opportunities.
New housing supply has grown at a pace that matches population growth rates, at the national level.
However, there is plenty of variation across the capital cities.
The strongest growth in the number of units has been in the territories (though this is from a low base), followed by Melbourne and Brisbane.
However, the strongest growth in the number of houses has been in Perth, at around 22%.
Sydney has experienced much lower growth in its number of houses, at less than 10%.
This reflects the very different patterns of development in the two cities.
In Perth, Brisbane and Sydney, increases in the supply of housing didn’t keep pace with population growth during, between 2006 and 2014.
However, the drivers of this shortfall are varied.
Perth’s population grew very strongly over the period that we studied.
The roughly one-quarter increase in population would stretch the capacity of most housing construction sectors.
However, even though Sydney’s population growth (at 14%) is below the average across all capital cities, its housing supply failed to match this growth.
These outcomes highlight the different demand and supply side factors operating across states.
We currently have a national housing policy narrative that is dominated by a consensus view that higher levels of housing supply are the solution to housing affordability problems.
While increased supply will always help take steam out of pressured markets, our study suggests a more nuanced approach is needed to the supply side, while not ignoring the demand side pressures.
It’s important that we identify those barriers to expanding affordable housing supply that have been impeded in the majority of our cities, especially for low income households.
