Because of increasingly restrictive legislation on family formation and reunification, and the economic development of their home countries, the number of immigrants from Turkey and Morocco has decreased sharply since 2003.[20] Immigrants from Turkey decreased from 6,703 in 2003 to 3,175 in 2006, and immigrants from Morocco decreased from 4,894 to 2,085.[21] Net immigration has slumped to a few hundred a year, and has even been negative in some years.[citation needed]
