French law facilitated the immigration of thousands of French settlers (colons in French language), ethnic or national French from former colonies of North and West Africa, India and Indochina, to mainland France. 1.6 million European pieds noirs settlers migrated from Algeria, Tunisia and Morocco. In the 1970s, over 30,000 French settlers left Cambodia during the Khmer Rouge regime as the Pol Pot government confiscated their farms and land properties. However, after the 1973 energy crisis, laws limiting immigration were passed. In addition, the country's birth rate dropped significantly during this time.
