Though widely perceived as one of the best integrated non-Western immigrant groups, there still remain some challenges for the Vietnamese community in Norway. A 2002 survey reported that 3.2% of Vietnamese Norwegians had been punished for breaking the law. The number for ethnic Norwegians was 1.35%. A social anthropologist studying the Vietnamese community said there was an "either...or" phenomenon among the Vietnamese, with those not succeeding in school falling into delinquency. The same trend has also been observed among the Vietnamese Americans. A stronger connection between the parents and the kids that fall out has been wanted. The relative low proficiency among Vietnamese in Norwegian, and a small vocabulary, has also been analysed as important challenges remaining.
