1. FINNISH POPULATION INFORMATION SYSTEM (PIS) The data on stateless persons residing in Finland can unfortunately not be broken down by countries of birth, as this information is not readily available in a report format from PIS. Similarly, there is no such data available regarding persons whose nationality has been registered as “unknown”. 71 Table 1: Total stateless population according to PIS (2002-2011) 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 Stateless 760 750 730 698 722 730 740 770 919 964 “Unknown” 618 773 760 753 636 77 487 454 387 360 Pending clarification 818 554 322 215 115 552 96 88 70 166 Source: Population Registration Centre and Statistics Finland, September 2012 Persons whose citizenship status is pending clarification and who are registered in PIS are in most cases children born in Finland whose citizenship status is pending determination by Migri,72 as can also be concluded from the high proportion; 92.6%, of these persons in age group 0-4 years (see table 2 below). It should be noted that data in the category of nationality pending clarification is generally transitional, and that persons in this category should remain there only for a limited period of time.

The age distribution of persons with unknown nationality is very similar to that of stateless persons. The proportion of persons under 20 years old is 14.3 % and those of the youngest children (0-4 years) 4.5 %, which is slightly higher than in the category of stateless persons. 71 Explained by the Population Registration Centre, e-mail of 21 August 2012. 72 This was referred to by Migri, the Population Register Centre and the Local Register Office of Helsinki.
