There can be no sugar-coating of the numbers. The religious statistics surfaced by the 2025 General Household Survey, published today (June 30), paint a sobering picture for the church in Singapore.
The 1.8-percentage-point dip in the overall percentage of Christians (Protestants and Catholics combined), from 18.9% to 17.1%, marks the first recorded decline in Christianity’s share of Singapore’s resident population after four decades of uninterrupted growth.
With the Catholic demographic growing, the overall fall was down to the notable drop in the Protestant population, from 11.9% to 9.5%.
These trends are reflected in the absolute numbers:
While the Catholic population rose by 13% since 2020, the Protestant population fell by almost 66,000 – a 16% drop, which again marks the first time that the Protestant population and the total Christian population saw a recorded decrease in Singapore.
This fall cannot merely be attributed to death by ageing, with drops noted in every age group. When comparing the same “cohort” between the 2020 Census of Population and the 2025 General Household Survey – for example, those that were 15-19 in 2020 would now be in the 20-24 age bracket in 2025 – every age group demonstrated a sharp decrease.
Coupled with the rise in those professing “no religion” – from 20% in 2020 to 23.9% in 2025 – there are clear signs of a drift away from Christianity in the Protestant denominations.
