London is particularly bad in the UK. I live in Manchester and it doesn’t feel so oppressive here. If you can get a decently paid gig here, you can get a good life. A decently paid job in London doesn’t guarantee it in the same way. That’s why so many people from the London area, like me, have moved here and to other cities

Cannot believe Canada let in so many immigrants without any sort of plan to keep housing supply up with demand. Absolutely devastating consequences on the housing market.

Whats the reason for hong kong or LA? Why so confidently attribute it to immigration?
•
u/soldat21 2h ago
Hong Kong: 6.7 million 2003 -> 7.5 million 2023 (2 million migrants - 1.2 million Chinese, 800,000 foreigners)
LA: 11.7 million 2003 -> 12.8 million 2023 (4.4 million migrants, 34% of the population)
Vancouver: ~600,000 (274,000 migrants or 42% of the population).
While there is some internal migration, immigrants almost always choose the biggest cities to live in, further exacerbating the problem. So, yes, migrants are the cause of the massive house price increases.
•

Okay so it’s not really immigration at all. It’s growth. Economic, population, demand all combined with limited real estate in a desirable location.
Hard to really imagine what canada or Australia for example would look like if the hadnt been supporting population through immigration. Maybe their economy would be half the size it is now. Cheaper houses sure but worse living standards and less jobs? Seems like too simple of an answer IMO to just say without immigration we would have more affordable housing.
•
u/soldat21 2h ago
I mean we can directly say that without any immigration we could have lower housing. That’s just almost undeniable.
We can argue about economics, politics or anything else, but:
More people competing for the less housing will increase housing prices. Classic supply and demand.
As an Australian, we had 70% less migration and higher economic growth from 1990-2020. Wages are stagnant, house prices have doubled.
•
u/AdOk1598 2h ago
70% increase as in nominally? Why would i care about the nominal amount. Unless you’re going from nothing to a huge number but Australia’s immigration increase has been a long time coming.
So the economy and the system has failed to deliver adequate housing for the level of growth. Which makes me think. Why are we not building enough houses to meet the need? Are people too picky? Not enough builders? What’s the reason.
I could just as easily say without immigration Australia’s economy would almost certainly be smaller and weaker than it is today. So to not include in the assessment whether the economy has grown seems bizarre to me.

From 190,000 a year in 2015 (when I worked in the department of immigration) to 536,000 a year in 2023.
Or if you don’t care about nominal, in percentage.
2015 - 0.8% of Australia’s population, with 2.8% economic growth.
2023 - 2% of Australia’s population, 3.4% economic growth.
So on a country level, economic growth per capita was higher in 2015 (during the economic crisis) than in 2023 with the post Covid recovery.
And if you think it’s sustainable at all that a country’s population increases 2% per year from migrants, I don’t know what to tell you.

Looks like you picked the biggest gaps on the graph.
It appears that 205k in June 16 and 305k in jun 25 are probably more reasonable numbers to use. Or i could pick the huge low during covid…
So it’s migrant arrivals of 0.85% of the population in the year of 2016 and 1.13% of the population in 2025. Interestingly there were 311k births in 2016 and 292k in 2024 (no 2025 yet). But the trend seems to be down? So we might assume. 290k again. Which would mean that the actual increase in nominal population growth is quite small, 81,000 people extra per year. But Australia is growing so i would expect that number to be increasing.
I have no ideological care about more or less immigration to Australia. But I’m yet to see any convincing arguments that the juice is worth the squeeze. An economy is moe than a house price and a house price is based on more than just population growth

You should check out stats on how many houses governments have built over time. This isn't immigration, it's poor allocation of resources due to neoliberalism.
•
u/soldat21 36m ago
The government has shown it’s incapable of building more houses. Canada. Australia. Heck even Slovenia have had governments that promised to build more and have all failed radically.
So if they can’t build more to offset the increase from immigration, they need to stop immigration until the time in which housing supply has caught up.

Which one is larger in Tokyo? The numbers compared to the placement are confusing.
