The Census at School site website contains a range of useful classroom resources, which explore the analysis of data collected in the most recent UK Census.
These are produced for a range of subjects.
For example, the 'How old is your height' activity, explores the changing heights of people through history.
It's a nice example of how young people can be involved in data collection which is then used to explore a relevant issue.
I wonder whether there are similar resources available to help 'unpick' the Census data collected in other EU countries ?
