The ABS Religious Affiliation Standard Classification is how ABS sorts religion answers from the Census.
The top level has nine groups. The largest is Christianity, with nineteen branches. The other eight are flat. Most cover one named faith group each.
The list is a tree. ABS rules drive it, not how a person sees their faith. Two people of the same faith can land in different groups if their write-in answers differ.
Place Forecast uses thirty of these groups in the Religion marker.
