Central Coast suburbs with the largest non-religious population
Niagara Park has the highest concentration, at 48.1% of residents (1,336 people). San Remo and Copacabana follow. These 15 suburbs came from a field of 58 eligible Central Coast suburbs.
This page ranks Central Coast suburbs by the share of residents who reported having no religion in the 2021 Census — the city's most secular neighbourhoods. Only suburbs with at least 2,000 residents are ranked.
Shares are the count of Central Coast residents who selected "No religion" divided by the suburb's total population, from the ABS 2021 Census religious-affiliation table — the same figures shown on each suburb page. Percentile ranks are computed within Central Coast's pool. Answering the census religion question is voluntary, so the true non-religious share may run higher than reported. This is descriptive demographic information, not a recommendation.

Ranked from 58 qualifying suburbs.
100% share of residents who reported this religion in the 2021 Census (the religion's count divided by the suburb's total population), percentile-ranked within Central Coast's candidate pool. Only suburbs with at least 2,000 residents qualify, and the larger absolute community breaks ties.

Common questions about this ranking
Which Central Coast suburbs have the largest non-religious population?
Niagara Park has the highest concentration, at 48.1% of residents (1,336 people). San Remo and Copacabana follow. These 15 suburbs came from a field of 58 eligible Central Coast suburbs. In Central Coast suburbs of 2,000+ residents, 39.5% of people reported having no religion (2021 Census).
How is this ranking put together?
Each Central Coast suburb is ranked by the share of its residents who reported having no religion in the 2021 Census — that group's count divided by the suburb's total population. Only suburbs with at least 2,000 residents are included, and percentile ranks are computed within Central Coast's pool, so the list reflects concentration relative to other metro suburbs.
Where does the data come from?
The Australian Bureau of Statistics 2021 Census, which asks every resident an optional question on religious affiliation. We use the published suburb-level counts — the same figures shown in the religion breakdown on each suburb page. Nothing is estimated or inferred about any individual.
Why would someone use this list?
Religious make-up is part of a suburb's character, and plenty of people are simply curious where a city's most secular pockets are. This is a factual demographic snapshot, not a judgement about any suburb, and not a recommendation to seek out or avoid anywhere.
How current is it?
The figures are from the 2021 Census, the most recent available until results from the August 2026 Census are released in 2027. The top 15 is recomputed whenever we refresh the census data.
