There were a few significant differences between the previous national census in 1900 and the 1910 census:

  • A complete date of birth should be stated for every individual, not only for 1-2 year old children as in 1900.
  • Norwegian-Americans who had returned to Norway should state the year of emigration and of return, as well as their residence in Norway before emigrating and their latest residence and occupation in America.
  • It should be stated if a person was unemployed.
  • The crew should be listed only for ships in Norwegian harbours and waters, not for Norwegian ships in foreign harbours and waters as in the 1900 census.
