The census is taken on a single day every 10 years, with the records being made public after 100 years. The censuses for 1801-1831 merely recorded the number of people in each village. However, the 1841 census was the first to record the names of all the people in each house. This site contains transcripts of all available censuses for Carlton and Willingham Green.
If you are interested in looking up a specific person then you should access the census via the alphabetical surname index on the Parish Register page, which indexes all the censuses in parallel. If you wish to browse a particular census for the whole parish then select one of the years below:
Note: Unfortunately the census returns for Carlton don't give the name or number of each houses apart from rare (ie important) cases, but they should be in order, and the street names are given. Bear in mind though that some houses may have counted for more households than they do today. And some houses have disappeared. Please - if you know from the inhabitants (or the old name of your house) which entry corresponds with your house please tell me as this will help in working out which houses the other people lived in! One way to find out which entries correspond to your house might be to start with the 1910 land tax survey - which comes with a map - and work backwards to 1901 (the latest published census).
All the censuses listed above have been transcribed from photocopies taken from either microfilm or microfiche available at the CRO, these microfilm copies are not as clear as they could be, so it is possible that errors have occurred in the transcription. Where there is known uncertainty, an asterix, "*", appears next to the word or initial.
Population over the years
The following chart and table (derived from the census data) shows how the population has varied over the years:
The table below shows a summary of the census data for 1991. It shows that no households have no car, 30% have one car, and 70% have two or more cars. Which by my calculations means there are around 120 cars in Carlton! Note that the number of houses for the earlier surveys (above) refers to the number of households - many of today's houses were in fact 2 or 3 semi-detached households back then!
Detailed statistics for the 2001 census are available from the Cambridgeshire county council web site.
