Table A2.

For each community, we calculate the average possession of each of the 20 religious attributes. We weight this by the probability of each configuration in the community, and convert it to a percentage (Self). We compare this to the average possession of the attribute across all configurations that are not in the community. Again, we weight this by the probability of each configuration and convert it to a percentage (Other). We calculate the difference (S-O), and show the three attributes for which each community differ most from the rest.
