Census data visualization

It's a pity that Per Henrik writes his blog mostly in Norwegian, so I cannot follow his writings much, but he has some interesting topics on his blog. In his latest posting, he has entered the census data from 1990 and 2000 into a Google spreadsheet to show the automatic diagrams made possible with this - from totally useless ones like the number of Christians in correlation to the percentage of female headed households, but also interesting things like the development of the average household size.
This diagram shows that while for most province the average household size decreased in that decade, it stayed almost constant in the three southern-most provinces, which in 2000 then became the three provinces with the largest household size. Don't know if or how this could be interpreted, and there are probably even more useful possible diagrams within this data. And it will become even more useful once the NSO has published the data of the 2010 census, or Per manages to find the same data from the earlier censuses.
