Singapore’s Fertility Debate Needs More Data — and Less Opinion

Singapore recently announced that its Total Fertility Rate (TFR) has fallen again, from 0.97 to 0.87, the lowest in the nation’s history. The news quickly triggered a wave of commentary. Fertility experts appeared overnight offering explanations and policy prescriptions — from housing costs to cultural attitudes.

Some opinions were thoughtful. Others clearly reflected personal agendas.

Rather than adding another opinion to the debate, it may be more useful to start with the data.

When we examine the numbers carefully, Singapore’s fertility challenge appears less like a sudden crisis and more like a long-developing structural shift.

Understanding that shift matters if we want meaningful solutions.

A Global Trend — Not Just a Singapore Problem

Singapore’s fertility rate is among the lowest in the world, but it is not unique.

Across the globe, fertility rates have been falling for decades. The global average has declined from about five children per woman in 1950 to roughly 2.3 today.

One pattern consistently appears in demographic data:

As countries become wealthier, fertility rates tend to fall.

This happens for several reasons:

higher education levels
longer life expectancy
urban lifestyles
later marriage
higher opportunity costs of raising children

However, some societies have fallen much further than others.

The countries with the lowest fertility rates today are concentrated in East Asia — including South Korea, Taiwan, Hong Kong, Japan, and Singapore.

These societies share several characteristics: rapid economic development, intense education systems, and high expectations around parenting.

Singapore sits firmly within this group.

Singapore’s Fertility Decline Began Decades Ago

One common narrative is that Singapore’s fertility decline was caused by the “Stop at Two” campaign of the 1960s and 1970s.

But the data suggests the decline was already underway.

At independence, Singapore’s fertility rate was around 4.6 children per woman. Over time it steadily fell, and by 1976 the national fertility rate had already dropped below the replacement level of 2.1.

It has remained below replacement ever since.

Fertility rates also differed across communities. Malays and Indians generally recorded higher fertility than Chinese residents, but the overall national trend was the same — a sustained decline.

This suggests that Singapore’s fertility challenge is not a recent phenomenon. It reflects a demographic transition that has been unfolding for decades.

What may feel like a crisis today is more accurately described as the accumulated consequences of long-term change.

Policy Responses Have Had Limited Impact

Since the late 1980s, Singapore has introduced multiple initiatives aimed at encouraging families to have more children.

In 1987, the government shifted from population control to encouragement with the campaign “Three or More, if You Can Afford It.”

Later schemes such as the Baby Bonus and Child Development Account (CDA) were introduced to offset the financial cost of raising children.

These policies likely helped families who were already planning to have children. But despite repeated enhancements, the overall fertility trend has continued downward.

This suggests that financial incentives alone are unlikely to reverse the trend.

The drivers of fertility behaviour appear to run deeper.

How Family Formation Has Changed

Looking beyond the headline fertility rate reveals several major behavioural shifts.

One clear trend is delayed parenthood.

In the past, women under 30 accounted for the majority of births. Today, women aged 30–34 form the largest group of mothers, while births among women aged 35–39 have been rising steadily.

At the same time, large families have almost disappeared.

Decades ago, families with five or more children were not uncommon. Today they are virtually nonexistent. Instead, one- and two-child families dominate births in Singapore.

Childlessness has also increased. Among married women in their thirties, a significant proportion now have no children at all.

These trends together push fertility rates lower.

Education and the Shrinking Childbearing Window

Singapore’s development strategy has successfully produced one of the most highly educated populations in the world.

This has brought enormous benefits: higher incomes, stronger economic growth, and a highly skilled workforce.

But education also influences family formation.

As people spend more years studying and building careers, they tend to marry and have children later.

The biological window for childbearing, however, does not expand in the same way.

While medical technology has extended reproductive possibilities somewhat, the optimal years for childbirth remain relatively fixed.

As couples delay starting families, the time available for having multiple children becomes shorter.

In other words, the sweet spot for childbearing is narrowing.

This means fertility policies may need to be highly targeted — not just encouraging couples to have children, but encouraging them to start earlier.

The Economics of Family Size

Another frequently cited explanation for Singapore’s low fertility rate is the cost of raising children.

Government data shows that median household income has risen to around $12,446 per month, and household income per person has also increased over the past decade.

At first glance, this suggests improving affordability.

But when we examine income alongside household size, the picture becomes more complex.

Across most income deciles, the average household size in Singapore is roughly three people — typically a couple with one child or one dependent parent.

In other words, income distribution already reflects relatively small households.

If families wish to maintain their relative economic standing within their income group, adding more children significantly changes the financial equation.

For example, assuming a family of four — two parents and two children — households below roughly the 70th income percentile would fall below the national median household income per person.

A decade ago the threshold was lower. Around 2018, households near the 60th percentile could still maintain median per-person income with two children.

Today the bar appears higher.

For families with three children, the threshold rises further. Only households around the 80th percentile and above can comfortably maintain median income per person.

This helps explain why one- and two-child families dominate, while larger families have become rare.

Relative Living Standards Matter

From a purely financial perspective, this creates a difficult trade-off.

Parents worry not just about meeting basic needs, but about ensuring that each child has access to opportunities — including education, enrichment programmes, and eventually university.

In Singapore’s highly competitive environment, families often prefer to concentrate resources on fewer children.

This suggests that fertility decisions are influenced not only by absolute income levels, but by relative economic standing and perceived opportunity.

A Collective Action Problem

From a national perspective, children generate broad economic and social benefits.

They eventually become:

workers
taxpayers
consumers
caregivers for the elderly
and, in Singapore’s case, future national servicemen

But at the household level, the incentives may look different.

Families who choose to have fewer children may enjoy higher financial flexibility. Yet the broader costs of low fertility — a shrinking workforce and ageing population — are borne by society as a whole.

Economists often describe this as a collective action problem.

What may be rational for individual households may not produce the best outcome for the nation.

Policy Can Influence — But Families Decide

Governments can shape fertility trends through incentives and policy design, but they cannot dictate family decisions.

Singapore will not legislate childbirth or force citizens to have children.

The final decision will always remain deeply personal.

But demographic outcomes ultimately reflect the collective choices of society.

If large numbers of citizens choose not to have children, or choose to have fewer children, the population will inevitably age and shrink.

In such circumstances, maintaining the economy and social systems will require population support from elsewhere.

For Singapore, that support typically comes through foreign workers and immigration.

This creates a tension in public discourse. Some Singaporeans express concerns about foreigners, yet many essential roles in the economy are already filled by them — from construction workers building homes, to nurses caring for patients, to service workers keeping the city running.

If fertility remains low, this reliance will only increase.

Demography leaves few alternatives.

Supporting Families Across the Life Cycle

Many current policies focus on supporting families during the early years of a child’s life.

But parents often worry more about long-term financial commitments, particularly education.

Singapore’s education system is highly competitive, and parents want to ensure their children have access to opportunities.

Policies that reduce long-term financial uncertainty may therefore influence fertility decisions.

For example, graduated subsidies for tertiary education based on family size could help reduce the perceived risk of having additional children.

Such measures would not encourage families to have children purely for financial gain, but they could help reduce the long-term financial anxiety associated with raising larger families.

Is Singapore Really a Difficult Place to Raise Children?

Despite local concerns, Singapore remains one of the most favourable environments in the world for raising children.

By many objective measures, it performs exceptionally well.

Singapore has:

among the highest household incomes and GDP per capita globally
one of the lowest child mortality rates in the world
some of the longest life expectancies
extremely low crime rates
and very low unemployment

Each generation has also seen improvements in living standards over time.

In structural terms, Singapore offers a high level of safety, stability, and opportunity for raising children.

And yet fertility remains extremely low.

This suggests the challenge Singapore faces may not simply be about money or policy incentives alone.

It may reflect deeper changes in how people think about family, opportunity, and the future.

A Data-Driven Conversation

Singapore’s fertility challenge will not be solved by a single policy.

It is shaped by economics, social expectations, family decisions, and long-term demographic forces.

Rather than debating the issue purely through opinion, it may be more productive to examine the data and understand the trade-offs families face.

To support this discussion, we have developed an interactive dashboard that allows readers to explore fertility trends, household income dynamics, and the economic implications of family size across different income groups.

Sometimes the most powerful insights emerge not from arguments, but from letting the data speak for itself.

A Final Invitation to the FYT Community

The charts and data in this article can surface patterns and insights, but data alone does not tell the full story. It still takes thoughtful people to interpret those insights, challenge assumptions, and translate numbers into meaningful narratives that inform better decisions. This is the essence of data storytelling — connecting evidence with context and judgment. If this analysis sparks questions, alternative interpretations, or different perspectives, I would love to hear them. At FYT, we believe that progress comes from open discussion grounded in data. Our community and workshops focus on helping professionals develop the ability not just to analyse data, but to turn insights into coherent stories that influence thinking and policy. Feel free to explore the interactive dashboard, share your own observations, and join the conversation. Sometimes the most valuable insight comes from the question someone else asks.
