Mining the Census

Results from the Australian census of 2011 are in, and number crunchers have been working the data. Someone has correlated religious belief with postcodes, and found that belief is highest in remote Indigenous communities and lowest in the counter-cultural town of Nimbin. Within the cities, inner areas are the strongholds of non-sbelievers; if you take a freeway out of the centre, you will move into areas of progressively higher belief. 

Someone else has determined the postcodes with the highest number of people who are both single and wealthy. In the state of Queensland, leaving aside the coal mining town of Moranbah, these are those of New Farm and Brisbane City; Kangaroo Point is also up there. So, if bumping into a wealthy single person in the supermarket is on your agenda, it is to such inner city areas that you should relocate.  (Note, however, that the mix of ‘wealthy’ and ‘single’ may include ‘gay’.)

I wonder whether the census data could be used to answer other questions. Would I be correct in thinking that belief becomes higher as you progress along the continuum single -> married -> being a parent -> being the parent of a large family? And if this is so, why should it be? What about a connection between wealth and belief? As to another possible connection, the answer may be supplied in a poem, the authorship of which escapes me:

One thing’s sure

And nothing’s surer

The rich get richer

And the poor get children.
