In addition to the indexes discussed in the article on England census records, there are census indexes specific to Norfolk county. One of the earliest census surname indexes available was one created for the counties of Devon, Norfolk and Warwick for the 1851 census. This index has been published on CD-ROM and is available at the Family History Library in Salt Lake City and at many family history centers. It may also be purchased.
An index has been created to the 1851 census of people of Norfolk and Suffolk origin who were living at the time in the greater London area. This index, on CD-ROM, is available at the Family History Library (CD no. 3791 pt. 2), and it may be purchased online from the Family History Shop in Norwich.
Parts of the 1861, 1871, and 1891 censuses of Norfolk are also indexed on FreeCen, which as the name implies, can be searched online for free.
