The 1910 census has been digitally transcribed and proofread from the original source. This immense work has been carried out between 2001 and 2009 by the National Archives’ (NA) transcription units in Stavanger and Voss (82,8 % of the census) and the Norwegian Historical Data Centre’s (NHDC) transcription unit in Målselv (17,2 % of the census). After the digitisation the data material has been converted, checked and adapted in different ways by computer, executed in cooperation between the NA in Oslo and the NHDC in Tromsø.
Between September 2009 and November 2010 the National Archives in Oslo has also carried out a comprehensive completeness and quality check of the data material. The data has been compared to the census statistics (NOS) and the aggregated census lists, also the house lists where necessary. This quality assurance work is at the time of publishing the census in the Digital Archives (December 1st 2010) carried through for every municipality in the country except for the capital Kristiania, which will be completed i January 2011.Transcription and computing errors that are revealed in the data from the census, are corrected continuously in the database, also in the data from other municipalities than Kristiania.
The NHDC has coded place of birth, occupation and other variables as a part of their preparation of the census for utilization in research. For more information, see their website: http://www.rhd.uit.no/indexeng.html .
About 65 man-years altogether have been spent on the digitisation of the 1910 census.
Unlike former censuses the 1910 census does not lack any whole municipalities in the original source material. Nevertheless, the completeness check carried out in the NA has revealed that about 175 house lists and a few family lists from different municipalities are missing. According to the area lists and main lists the missing house and family lists contain about 4850 individuals. In addition, all the ship lists are missing. Among the deficiencies in the census material are all the mental hospitals in the country and the royal family. A complete list of the deficiencies will be prepared and published here, probably in early February 2011.
