2011 census of England and Wales

The UK Office of National Statistics have released statistics from the 2011 Census of England and Wales. It does a good job presenting the information graphically, sometime audio-visually, exploiting local variations and comparing 2011 with data from previous censuses.
There's a good offering on the changes over the past hundred years with age pyramids and an option to hear the descriptions explaining the changes and why they happened.  www.ons.gov.uk/ons/interactive/vp1-story-of-the-census/index.html.
