Six million used to sound like a distant planning number. Today, it is Singapore's reality. As of June 2025, 6.11 million people live on this island, a new record for a country that cannot simply build outwards when demand rises.

For regular homebuyers, homeowners and property investors, this is not just a population statistic. It is a signal of how demand for homes, rentals, infrastructure and land could evolve over the coming decades.

Population isn't just a demographic statistic. As we dive deeper, you'll see just how much it affects real estate.

There has always been a link between population growth and housing demand. Historically, when populations grow faster than housing supply, prices tend to rise. When populations stagnate or shrink, housing markets often soften.

For example, after the Second World War ended, countries like the United States experienced a surge in population known as the "baby boom". This led to a massive demand for housing from the 1950s onwards. Entire suburbs expanded rapidly because millions of young families were suddenly looking for homes at the same time. Property values climbed alongside population growth and urban expansion.

China saw something similar in the past decades. Hundreds of millions of people moved from rural areas into cities, creating enormous demand for apartments in places like Shanghai, Shenzhen, and Beijing. Developers raced to keep up. In many cities, property prices climbed faster than wages because housing demand exploded alongside migration and economic growth.

It was like that in Singapore too. During the 2000s and early 2010s, strong immigration and economic expansion put a lot of pressure on both the HDB resale and private property markets. Prices climbed rapidly as new household formation outpaced available supply.

On the flip side, countries facing population decline often struggle with weaker housing demand. Japan is one of the clearest examples. While central Tokyo remains expensive due to strong economic activity, many rural towns now face falling property prices and abandoned homes because younger populations have moved away and birth rates remain low. In some areas, houses are literally being abandoned.

Obviously, all these countries are different from land-scarce Singapore. But we can still learn from their history.

Ultimately, the relationship between population and housing is driven by demand for space. More people means more households. More households mean greater competition for homes, rentals, infrastructure, and land.

Of course, population growth alone does not guarantee rising property prices. Interest rates, government cooling measures, income growth, job creation, and supply pipelines all play major roles too.

Unlike larger countries, Singapore cannot just expand outward. We are, by design and by geography, a city that builds upward and inward. This is why comparisons with other dense cities, such as Hong Kong, often come up. Although, Singapore's planning model and housing policies are very different. Urban planners here operate under constraints that other nations do not face. From flight path restrictions limiting building heights, water catchment areas restricting land use, to old developments taking up meaningful portions of the island.

Land reclamation has expanded our footprint over the decades. But, it is expensive, time-consuming, and has its limits. That's why the government's approach has been to build denser and taller. And, they have to plan ahead, given that the population has continued to grow steadily over the decades.

Of the 6.11 million people living here, 3.66 million are citizens, 540,000 are Permanent Residents (PRs), and 1.91 million are non-residents (comprising foreign workforce, migrant domestic workers, dependants, and students).

The non-resident population alone grew by 2.7% in just one year, primarily driven by Work Permit Holders brought in to support major infrastructure projects like Changi Terminal 5 and the national push to ramp up housing supply.

In 2026 alone, HDB plans to launch around 19,600 BTO flats. And the Government Land Sales programme released sites for nearly 10,000 private residential units in 2025. That's why both the HDB and private market have been moderating recently. Of course, this doesn't mean the market is crashing. On the contrary, this is part of the government's efforts to keep it stable.

As more people enter Singapore, the demand for housing will be seen across different segments of the market. Some may rent. Some may eventually buy resale flats. Others may enter the private market later on.

Even though our population is slowly rising right now, there is a real concern about our fertility rate. As marriage rates decline and the trend to have fewer or no children grows, Singapore's total fertility rate dropped to a new record low of 0.87 in 2025, according to the Department of Statistics. For context, the replacement level (the rate needed to keep a population stable without immigration) is 2.1. We are sitting at less than half of that.

Deputy Prime Minister (DPM) Gan Kim Yong stated that without interventions, the citizen population could start to shrink by the early 2040s.

To make matters worse, the proportion of our citizen population aged 65 years and above is rising. By 2030, around 1 in 4 citizens will be a senior. What does an ageing, shrinking population mean for real estate?

In the short term, demand remains supported by existing household formation trends. But over the long term, a population that is getting older and smaller means fewer new households being formed, fewer first-time buyers entering the market, and potentially less demand for larger family-sized units. If there is no sustained demand, it could spell trouble for our property market, not unlike Japan's case.

One way the government is addressing this issue is by launching a "marriage and parenthood reset". It's supposed to build on their current efforts to enhance support for marriage and parenthood, cultivate positive mindsets, and work with employers to foster family-friendly workplace cultures and practices.

But this alone isn't enough.

Given the birth rate crisis, immigration might be a demographic necessity. Immigration helps moderate the impact of ageing and low birth rates, keeps the citizen population from shrinking, and brings skills and dynamism into the economy.

In his February 2026 speech, DPM Gan stated that the government plans to grant citizenship to 25,000 to 30,000 new citizens annually over the next five years. The PR intake is expected to rise to about 40,000 per year, up from 35,000 in 2025.

However, immigration continues to be a polarising subject and it would be disingenuous to pretend otherwise. When the government released the Population White Paper in 2013 (which projected a total population of up to 6.9 million by 2030), it sparked a rare and sizable public protest, with around 5,000 people gathering at Hong Lim Park. The concerns then were about jobs, transport overcrowding, school places, and yes, housing costs.

But this time around, the government is committed to manage the pace of immigration in tandem with infrastructure, be selective about who is brought in, and follow through with integration efforts. An acknowledgement that past mistakes should not be repeated.

The immigration debate is not one with a clean resolution. Reasonable people are entitled to their concerns. But we can't dispute that without some level of carefully managed immigration, Singapore's demographic and economic trajectory can become significantly more difficult to navigate.

A record-low birth rate, an ageing citizen core, and a government doubling down on immigration are not background noise. These are real concerns that can affect the market in the coming decades.

In the short-term, housing demand is likely to remain supported by population growth, immigration, and continued household formation. That is why the government is aggressively ramping up housing supply while carefully managing prices through cooling measures and land sales.

But in the long-term, an ageing population and persistently low birth rates could eventually slow housing demand if left unaddressed. This is why immigration will likely remain a key part of Singapore's economic and demographic strategy, even if it remains politically sensitive.

For homeowners and investors, the takeaway is simple. Real estate is not just about interest rates or launch prices. Demographics matter. Population trends influence who needs homes, what kinds of homes are in demand, and how sustainable long-term price growth may be.

In a country as land-scarce as Singapore, even small shifts in population can have a significant impact on the property market. So, demographics are worth factoring into how you think about the home or investment you hold today.
