On 23rd September 1910 the Norwegian government decided that a public census was to be held by 1st December that year. The census should cover the whole country, i.e. it was to include all residencies and all individuals living both in rural districts and in cities and towns. Additionally, all seamen on board both Norwegian and foreign ships located in Norwegian harbours and in Norwegian territorial waters should be listed in separate "ship lists". The census was nominative, i.e. all individuals should be listed by name. This was the sixth nominative census to be held in Norway (the former in 1801, 1865, 1875, 1891 and 1900). The implementation of the census started on Thursday December 1st and was completed a couple of weeks later.
