Cultural diversity
Religion
About this topic
Religion records a person's stated religious affiliation, including no religion and not stated responses. It is a measure of cultural identity and belief rather than practice or participation.
This topic helps show the religious diversity of an area and can support planning for community facilities, faith-based services, and inclusive engagement. It is best interpreted with ancestry, birthplace, and language, which together provide a broader picture of cultural composition.
Interpretation notes
- This records stated religious affiliation, not attendance or level of religious practice.
- No religion and not stated are part of the overall picture, so interpretation should consider both affiliation and non-response.
