Dear Jayne, Hi. It looks like we are both on the NB mailing list now. My Derby research hit a brick wall, so I decided to look up another blind alley. The reason the 1881 census has fewer CDs than the UK census of 1871 is that there were many fewer people to enumerate in Canada. In 1881, there were approximately 3.6 million people in Canada while there were about 26 million people in the UK census. Therefore, fewer CDs needed. If you or other listers are interested in seeing the migration patterns in Canada from 1891 to 1921, please check out the following site: http://www.ucalgary.ca/applied_history/tutor/canada1891/index.html You will be amazed at how the various waves of migration formed our county. Hope this helps with some of your research by proving a context fro how they lived and worked. Kindest regards, Anne Clark-Stewart Mississauga, Ontario, Canada
