As of 1995, Slovenia was harboring 29,000 refugees from the former Yugoslav SFR. Of the 5,000 to 10,000 that remained in 1999, most had opted not to take Slovene citizenship during a six-month window of opportunity in 1991–92 and had been living in the country as stateless persons ever since. In 1999, Parliament passed legislation that offered these persons permanent resident status; a six-week window for applications closed at the end of the year. The net migration rate in 2000 was 0.5 migrants per 1,000 population. The number of migrants living in Slovenia in that year was 51,000. The government views the migration levels as satisfactory.
