Fig. 9 - People of unknown nationality born in NL with no residence permit - father's country of birth (N>50) 400 350 300 250 200 150 100 50 0 Source: CBS, situation 1 January 2010. “N > 50” indicates that data is only included where it concerns at least 50 individuals. 72. It is interesting to note that 90 persons born in the Netherlands to a father also born on Dutch territory have no known nationality. Although no clear information is available, it may be that part of this figure corresponds to individuals who lost their Dutch citizenship because they fought in the Spanish civil war, complemented by a statistical “remnant” of children born out of wedlock between April 2003 and March 2009 (see section 3.2). In addition, it should be noted that the vast majority (94 per cent) of Dutch-born persons of unknown nationality without a residence permit appear to be children, born in the 2000s, pointing to the difficulties in acquiring a nationality for many children born to foreign parents in the Netherlands. Presumably the high numbers of persons of Afghan, Iraqi and Somali origin visible in figures 8 and 9 reflect those whose claim to asylum was rejected due to absent or questionable (identity) documents, but who did not leave the country after this unfavourable decision. It is impossible to tell precisely how many people of unknown nationality experience all difficulties related to statelessness, but cannot live up to the nofault procedure’s high standard of proof and are thus left without a permit. Nonetheless, judging by the data displayed in figures 8 and 9, persons of Somali, Yugoslav and Soviet origin, as well as those originally from Angola, Burundi, China, the Democratic Republic of the Congo, Guinea, Sierra Leone and Sudan are at particular risk of being left without both an (agreed upon) nationality and a permit to reside. 32 Mapping statelessness
