Singapore’s Population in Brief 2026, released on September 25, describes a country growing in size while its citizens grow older. The headline milestone is clear: 21.4% of citizens were aged 65 or above in June 2026. Understanding who is counted, however, is essential to understanding the “super-aged” label.

Why the definition matters
The 21% threshold for a super-aged society refers, in the UN definition cited by Singapore’s population authorities, to the share of the population aged 65 and above. Singapore’s reported milestone applies the threshold to citizens instead of everyone living in the country, including permanent residents and non-residents.

That difference is substantial: citizens accounted for 3.68 million of Singapore’s 6.21 million people in June 2026. Among residents—citizens and permanent residents together—the share aged 65 and above was 19.5%. That resident figure is below 21%, but it is still not a total-population measure; the supplied figures do not establish whether Singapore crossed the threshold using the UN’s denominator.

How quickly are citizens ageing?
The share of citizens aged at least 65 rose from 13.7% in 2016 to 20.7% in 2025 and 21.4% in 2026—a gain of 7.7 percentage points over the decade. The number aged at least 80 reached 152,000, compared with 95,000 in 2016, an increase of 60%.

The government estimates that more than one in four citizens will be 65 or older by 2035. It also projects that the share aged 20 to 64 will remain broadly stable between 2030 and 2035, though the cited summary does not explain why. These projections concern citizens, not the entire population.

Age statistics should likewise be compared on the same basis. Singapore’s statistics department puts the resident median age at 43.6 years in 2026; that figure should not be presented as the citizen median age. A previously reported resident old-age support ratio of 3.3 in 2025 is not a verified ratio for 2026.

Why the population grew despite ageing
Singapore’s total population increased 1.6%, from 6.11 million in June 2025 to 6.21 million in June 2026. Citizens increased 0.7% to 3.68 million, permanent residents numbered about 550,000, and non-residents reached 1.98 million. Reporting on the release attributes most of the overall increase to non-residents, including foreign workers; construction work associated with projects such as Changi Airport Terminal 5 was among the factors identified.

Population growth therefore does not reverse the citizen-ageing trend. It also should not be taken, on its own, as evidence that births have recovered.

Births, marriages and immigration
Singapore recorded 26,071 citizen births in 2025, down 10.8% from 2024. The government separately described the preliminary resident total fertility rate for 2025 as 0.87 births per woman, down from 0.97 in 2024. Birth counts and fertility rates measure different things, and “citizen” and “resident” are different populations.

Citizen marriages also declined: the reported 2025 count was 21,671, versus 22,955 in 2024. Among citizen marriages in 2025, 19% were inter-ethnic and 37% were transnational; both shares were described as broadly stable over the longer term. Earlier government figures show that the median ages at first marriage for citizen grooms and brides had risen to 30.8 and 29.1 years, respectively, by 2024—not a newly verified 2025 measure.

In 2025, Singapore granted 25,094 citizenships and 35,352 permanent residencies. Annual averages for 2021–2025 were 22,400 citizenships and 34,600 permanent residencies, above the respective 2016–2020 averages of 20,600 and 31,200. Immigration can add to population growth, but it does not change the fact that the existing citizen population is ageing and births have fallen.

One further distinction matters when reading the citizenship figures: since Population in Brief 2025, citizenships granted by descent to eligible overseas-born children of Singaporean parents have been excluded from the reported citizenship-grant total. The 25,094 figure should therefore not be used to infer how many such children received citizenship in 2025.
32
The report’s clearest message is not that every person in Singapore belongs to a population that has crossed the UN threshold. It is that Singapore’s citizens have crossed the 21% mark, while a growing total population and continued immigration coexist with fewer births and a rapidly ageing citizen population.
