Open Data Mashup: UK National Census 2011

For the first of our Open Data Mashup blog series (ODMs) we are using the UK National Census 2011 data that has been made publicly available by the Office for National Statistics (ONS). Although the data is relatively old, it was only released on 23rd January 2014. The fact (or statistical) data has been provided by ONS in CSV format but the lookup/reference data is supplied in a PDF document. The dataset is a 1% representative sample of all the Census 2011 results. ONS refer to it as a 'Teaching file' and it contains over 500,000 rows of data.
