The proportion of Singapore residents aged 25 to 34 who remain single increased notably from 2020 to 2025, especially among Chinese residents, according to the latest General Household Survey [1, 2]. Among women aged 25 to 29, 73.4% have never married in 2025, up from 69% in 2020 [1, 2]. For men aged 30 to 34, this figure rose to 47.6% from 41.9% in 2020 [1, 2]. Singlehood and marrying later are more common among Chinese residents compared to Malay and Indian residents [1, 2].
Despite this trend, married couple-based households with children remain the largest household type, making up 47.6% of all households in 2025, a slight decline from 50.4% in 2020 [1]. The share of dual-career couples increased to 56.6% in 2025, up from 52.5% five years prior [1]. Women who had been married had fewer children on average compared to five years earlier [2].
The Singapore resident population in 2025 stood at about 4.2 million [2]. Among all residents, the proportion with no religious affiliation grew to 23.9% in 2025, up from 20% in 2020 [3, 4, 5]. The rise was most noticeable in the 35 to 44 age group, where those with no religion increased by 6.7 percentage points since 2020 [3, 4, 5]. Younger residents aged 15 to 24 are also more likely to have no religion, at 26.8%, compared to 19.4% among those aged 55 and above [3, 4, 5].
Religious adherence shifted with declines in Buddhists (30.9%), Taoists (7.3%), Christians (17.1%), and Muslims (15%) reported in 2025. Hinduism was the exception, rising slightly from 5% to 5.4% [3, 4, 5]. Among residents holding university qualifications, the proportion identifying as Christian fell from 28.3% in 2020 to 24.9% in 2025 [3, 4, 5].
Language use at home is changing, with English nearing 60% as the main language spoken, while Chinese dialects, Mandarin, Malay, and Tamil all declined in use [1, 3, 4, 5, 2].
The 2025 General Household Survey builds on baseline data collected in the 2020 Census, which first established trends in marriage, religion, and households for comparison [1, 3, 4, 5].
