This project aims to provide a "free-to-view" online searchable database of the 19th century UK census returns for 1841 to 1891.
FreeCEN is part of FreeUKGEN, an initiative aimed at helping make high quality primary (or near-primary) records of relevance to UK genealogy conveniently and freely available online, in a coherent, easy to access and search, information retrieval system.
Other projects associated with the FreeUKGEN initiative are FreeBMD and FreeREG.
