Population censuses in the UK have been held nearly every 10 years since 1801. In 2011 a Census was carried out on Sunday 27 March. The results provide comparative statistics for all 650 parliamentary constituencies in the UK.

There is also a downloadable Excel tool that lets you select a constituency, view statistics and print customised tables.
The Library has also produced a set of interactive tables that compare constituency Census results. Follow the links below:
You can also explore these topics with Constituency Explorer, an interactive data visualisation tool.
