free census

As well as familysearch.org there are some other good free sites such as

freecen.org.uk

This has transcriptions of UK censuses. In Scotland there are mainly only 1841 and some 1851 ones available.

I use it a lot for 1841 and I like it because you can click on the previous or subsequent households to check out the neighbours and neighbouring addresses.

Search either on Census Place or Census County.

You can also try searching on street name if you don't get a result using the surname.
