England began taking a census every ten years, beginning in 1841. It wasn't until the next census, in 1851 that data about family relationships was collected, making the census more useful for genealogy purposes. As in the United States, in order to protect privacy, details related to any specific individuals are not released for 100 years. In order to prevent duplicate counting, only those who were staying at the address being counted on the night of the "Census Day" were recorded. As a means of identifying census data, each year of census records are assigned a class code as follows: Year Class Code Census Day 1841 HO107 1851 HO107 (same as 1841) March 30th 1861 RG9 April 7th 1871 RG10 April 2nd 1881 RG11 April 3rd 1891 RG12 April 5th 1901 (won't become available until 2001) The country was divided into Enumeration Districts which included many places or just parts of one place. A place might be a Parish, a "Hundred" (groups of Parishes), or registration districts and sub districts. All the records from a given Enumeration District were gathered into a Census Book with numbered pages. The term "folio" refers to both sides of a sheet in the census book, where "recto refers to the front of the sheet and "verso" refers to the back of the sheet.. For filing purposes, these census books are gathered into "pieces" each of which is assigned a number and consists of a few hundred pages of census data. In this way, Piece 137 of the 1871 census is identified as "RG10/137". Depending on the volume of data, a "piece" might be part of a census book or several census books. Each census year has a Place Name Index and a Reference Book. Next to each place in the Place Name Index a number (or numbers), which indicate where to search next:
With this organization, you still have to know where your ancestors were on the "Census Day". Over the years, groups have produced several indexes to overcome this problem. The following types of indexes are generally available, (with the indicated color-coding sometimes used):
Indexes prepared by LDS Family History Centers, also have a microfilm number which can be used at a Family History Center, to access the specific microfilm containing photos of the actual census pages. 2The United States 1880, the British 1881, and the Canadian 1881 censuses can be searched online.
