Europe's housing crisis is usually discussed as though houses have somehow acquired a life of their own. Rents rise, vacancy rates collapse, young people remain with their parents, families crowd into inadequate accommodation and governments announce another package of subsidies, planning reforms or rent controls. What often receives less attention is the elementary arithmetic sitting underneath the market. If the number of people needing accommodation rises faster than the number of dwellings available to accommodate them, the pressure has to emerge somewhere.
That is the point made forcefully in a recent Remix News article using Berlin as its example. The article goes too far when it presents mass immigration as essentially the explanation of Europe's housing crisis, because housing markets are affected by interest rates, construction costs, planning restrictions, household formation, land availability, investment and decades of inadequate building. But strip away the polemics and an important point remains. Immigration increases population, population increases housing demand, and when housing supply cannot respond quickly enough, additional demand intensifies competition for the existing stock.
Berlin provides a particularly interesting case because its own housing authorities acknowledge the underlying demand-and-supply problem. The Investitionsbank Berlin housing report says the city's population has been growing almost continuously since 2015 while new construction has encountered increasingly difficult conditions. In 2024 Berlin recorded net external migration of 27,107 people, including net international immigration of 41,862. Berlin simultaneously lost residents to surrounding regions. Most strikingly, Berlin's natural population change has been negative since 2022: deaths exceed births. Recent population growth has therefore depended upon migration rather than natural increase.
That matters because immigrants do not arrive as abstract units in a statistical table. They require bedrooms, apartments and houses just like everybody else. They compete in the rental market, buy homes, establish families and form households. There is nothing mysterious or morally sinister about this. It is simply what human beings do. The economic question is whether the housing supply expands sufficiently rapidly to accommodate the additional population without imposing substantial costs upon people already competing for housing.
In Berlin it has not. The city's official housing reporting describes supply as insufficient to satisfy demand, particularly for affordable accommodation. The Investitionsbank Berlin reported Berlin's population rising by 22,884 people in 2024 while 15,362 dwellings were completed. Building permits had meanwhile fallen to 9,772 before recovering during 2025. Berlin ended 2025 with about 2.07 million dwellings, only 10,766 more than a year earlier. High construction and financing costs, planning requirements and other constraints make an immediate supply response impossible.
This is the crucial interaction. Immigration by itself does not mechanically determine rents. If a city could produce abundant additional housing rapidly and cheaply, population growth could be accommodated with much less pressure upon prices. Conversely, restricting immigration would not magically abolish every housing problem created by zoning, construction costs, low productivity or monetary conditions. But when governments pursue rapid population growth while presiding over a housing system incapable of expanding at the same rate, they are increasing demand faster than supply can adjust.
Berlin's latest figures make the demographic component especially difficult to ignore. By the end of 2025 the population had reached about 3.7 million, increasing by roughly 15,300 during the year. A 2026 housing-market assessment concluded that international immigration was the sole source of that population growth because deaths continued to exceed births. Whatever political position one takes on immigration, those additional residents necessarily added to aggregate housing demand.
The pressure is visible beyond Berlin. Eurostat reports that 16.9 per cent of the EU population lived in overcrowded households in 2024, while 8.2 per cent spent at least 40 per cent of disposable household income on housing. The experience is especially difficult for migrants themselves. In 2024, 33 per cent of non-EU citizens lived in overcrowded housing compared with 13.7 per cent of nationals, while 18.8 per cent of non-EU citizens experienced housing-cost overburden compared with 7.6 per cent of nationals. Immigration therefore does not simply create additional competition affecting established residents. Migrants themselves frequently end up among those suffering most severely from the resulting housing scarcity.
This is where the debate becomes politically uncomfortable. Immigration policy is commonly discussed separately from housing policy, as though one department can determine how many additional people will enter a country while another department can somehow find the houses later. But population policy is housing policy. Every migration target carries an implied requirement for additional dwellings, roads, water, electricity, schools, hospitals and transport. Governments can reasonably argue that immigration brings economic, humanitarian or demographic benefits, but those benefits do not repeal physical constraints.
Australians should recognise the problem immediately because we have been conducting much the same experiment. Australia's population increased by 412,500 people in the year to December 2025. Natural increase contributed 111,500, while net overseas migration contributed 301,000. In other words, almost three-quarters of that annual population increase came through net overseas migration. There were 563,500 overseas migration arrivals and 262,600 departures during the year.
Again, those numbers are people, and people need somewhere to live. Yet Australia cannot manufacture houses at the speed with which governments can issue visas. In the March quarter of 2026 only 48,012 dwellings were commenced, seasonally adjusted, and commencements actually fell 11.2 per cent from the preceding quarter. Building approvals subsequently improved, reaching 18,328 dwellings in June, but an approval is not a completed house. Construction requires land, finance, materials, tradespeople, infrastructure and time.
The resulting housing market has become extraordinarily expensive. ABS figures put the mean Australian dwelling price at approximately $1.1 million in the June quarter of 2026. South Australia's mean was about $979,600, Queensland's $1.13 million and Western Australia's $1.124 million. Prices softened nationally during that particular quarter, but the total value of Australian residential property was still 8.5 per cent higher than a year earlier.
None of this establishes that immigration alone caused those prices. It would be bad economics to claim that it did. Australia has restrictive planning systems, expensive land development, infrastructure bottlenecks, construction-industry capacity problems, taxation incentives affecting property investment, high building costs and long-standing failures to produce sufficient housing. Interest rates and credit conditions also matter enormously. A serious analysis has to acknowledge all of these factors.
But acknowledging multiple causes does not make population growth disappear. Housing demand depends substantially upon the number of households seeking accommodation. If governments add hundreds of thousands of people while the housing stock increases much more slowly, the newcomers do not somehow stand outside the property market. They enter it. Some buy, many rent, some share accommodation and others remain with relatives. The adjustment appears through some combination of higher rents, higher prices, lower vacancy rates, crowding and displacement towards cheaper locations.
Australian migrant data illustrates the last of these pressures. ABS figures show that in 2021, 11 per cent of permanent migrants lived in dwellings requiring one or more additional bedrooms, compared with 6.8 per cent of the Australian population generally. Among migrants who had been in Australia for fewer than five years, the figure was 17 per cent. Humanitarian migrants experienced particularly high overcrowding. Once again, migrants themselves can become victims of a housing system asked to absorb population faster than adequate accommodation is produced.
There is an important moral point here that gets lost when this issue is reduced to slogans about being either "pro-immigration" or "anti-immigration." Saying that an additional million people require additional houses is not an attack upon those million people. It is arithmetic. A migrant family searching desperately for a rental property is participating in exactly the same constrained market as a locally born young couple trying to leave their parents' house. Both suffer when governments allow housing demand to outrun supply.
Governments generally respond that the answer is to build more. In principle, of course it is. If a country wants rapid population growth without deteriorating housing affordability, it needs rapid housing growth as well. The problem is that "build more houses" is easier to announce than accomplish. Berlin's authorities themselves point to high construction and financing costs and difficult building conditions. Australia faces its own shortages of trades, infrastructure constraints, approval delays and construction costs. Houses cannot be summoned into existence by ministerial press release.
This creates an obvious policy constraint. Immigration can be altered comparatively quickly; the housing stock cannot. A government can change visa numbers within a budget cycle, whereas turning raw land into serviced suburbs or replacing low-density housing with apartment developments may take years. If housing supply is highly constrained in the short run, governments that substantially accelerate population growth should expect housing scarcity to worsen before builders have any possibility of catching up.
That is the lesson linking Berlin and Australia. It is too simple to say that immigration caused every element of either housing crisis, but it is equally implausible to pretend that very large migration-driven increases in population have nothing important to do with housing demand. Berlin's official statistics show a city whose natural population is declining but whose population continues growing through migration while affordable housing remains scarce. Australia's statistics show population growth overwhelmingly driven by overseas migration at a time when housing construction has struggled to keep pace.
There is no economic law requiring countries to pursue maximum population growth, just as there is no law requiring them to close their borders. Governments make choices about immigration because they believe those choices bring benefits. They should therefore also account openly for the costs, including the additional housing and infrastructure required by the population they choose to admit.
The basic equation is not complicated. A country cannot continuously increase the number of people competing for accommodation, fail to increase accommodation at anything like the necessary rate, and then profess astonishment when rents rise and young people cannot afford homes. Europe is discovering that lesson in cities such as Berlin. Australia is discovering it in Sydney, Melbourne, Brisbane, Perth and Adelaide. Whatever one thinks immigration policy ought ultimately to be, pretending that immigration and housing are separate subjects has become impossible.
