On April 30th, 1815 the Norwegians were counted. The 1815 Census is in fact only numbers, but there are also some name lists. These are now available in the Digital Archives.
After Norway and Sweden had formed a union in 1814, the Swedes needed a statistical survey of the Norwegian economic situation. The 1815 Census was primarily a numeric census, but some of those responsible for the enumeration made name lists as basis for their numeric lists. The nominative lists that we know of are now scanned and some are even transcribed. To celebrate the 200 years' anniversary for the census, you now find both scanned and transcribed versions of the 1815 Census available in the Digital Archives.
