I think you’ll find this of interest, from the Office of National Statistics… to quote them:

The Neighbourhood Statistics (NeSS) Data Exchange is a new online service designed to make it easier for other systems to interrogate and engage with the NeSS Datastore. Using machine to machine technology it speeds up and simplifies data requests, allowing access to over 300 geographically referenced datasets, free of charge.

Click on the link http://www.neighbourhood.statistics.gov.uk/dissemination/ and put your Charfield postcode in. Select ’more areas…’ and then parish to pull out the data specific to Charfield… Lots to look at.
