Demographics
Unlike other European countries, France did not experience a strong population growth in the mid and late 19th century and first half of the 20th century (see Demographics of France). This would be compounded by the massive French losses of World War I — roughly estimated at 1.4 million French dead including civilians (see World War I casualties) (or nearly 10% of the active adult male population) and four times as many wounded (see World War I) — and World War II — estimated at 593,000 French dead (one and a half times the number of U.S. dead), of which 470,000 were civilians (see World War II casualties). From a population of around 39 million in 1880, France still had only a population of 40 million in 1945. The post-war years would bring a massive "baby boom", and with immigration, France reached 50 million in 1968. This growth slowed down in 1974.
Since 1999, France has seen an unprecedented growth in population. In 2004, population growth was 0.68%, almost reaching North American levels (2004 was the year with the highest increase in French population since 1974). France is now well ahead of all other European countries in population growth (except for the Republic of Ireland) and in 2003, France's natural population growth (excluding immigration) was responsible for almost all the natural growth in European population (the population of the European Union increased by 216,000 inhabitants (without immigration), of which 211,000 was the increase in France's population alone, and 5,000 was the increase in all the other countries of the EU combined).
Today, France, with a population of 62 and a half million, or 65 million including overseas territories, is the third most populous country of Europe, behind Russia and Germany.
Immigration in the 20th century differed significantly from that of the previous century. The 1920s saw great influxes from Italy and Poland; in the 1930-50s immigrants came from Spain and Portugal. Since the 1960s however, the greatest waves of immigrants have been from former French colonies: Algeria (1 million), Morocco (570,000), Tunisia (200,000), Senegal (45,000), Mali (40,000), Cambodia (45,000), Laos (30,000), Vietnam (35,000). Much of this recent immigration was initially economical, but many of these immigrants have remained in France, gained citizenship and integrated into French society. Estimates vary, but of the 60 million people living in France today, close to 4 million claim foreign origin. This massive influx has created tensions in contemporary France, especially over issues of "integration into French society" and the notion of a "French identity", and in recent years the most controversial issues have been with regards to Muslim populations (at 7%, Islam is the second largest religion in today's France; see Islam in France).
Eastern-European and North-African Jewish immigration to France largely began in the mid to late 19th century. In 1872, there was an estimated 86,000 Jews living in France, and by 1945 this would increase to 300,000. Many Jews integrated (or attempted to integrate) into French society, although French nationalism led to anti-Semitism in many quarters. The Vichy regime's collaboration with the Nazi Holocaust led to the extermination of 76,000 French Jews (the Vichy authorities however gave preferential treatment to "integrated" Jews who had been in France from two to five generations and who had fought in World War I or held important administrative positions in the government), and of all other Western European countries, this figure is second only to Germany; but many Jews were also saved by acts of heroism and administrative refusal to participate in the deportation (three quarters of France's Jewish population was spared, a higher proportion than any other European country touched by the holocaust). Since the 1960s, France has experienced a great deal of Jewish immigration from the Mediterranean and North Africa, and the Jewish population in France is estimated at around 600,000 today.
Around the start of the 20th century, almost half of all Frenchmen depended on the land for their living, and up until World War II, France remained a largely rural country (roughly 25% of the population worked on the land in 1950), but the post-war years also saw an unprecedented move to the cities: only around 4% of the French continue to work in farms and 73% live today in large cities. By far the largest of these is Paris, at 2.1 million inhabitants (11 million in the Parisian region), followed by Lille, Lyon, Marseille (upwards of 1.2 million inhabitants each). Much of this urbanization takes place not in the traditional center of the cities, but in the suburbs (or "banlieues") that surround them (the cement and steel housing projects in these areas are called "cités"). With immigration from poorer countries, these "cités" have been the center of racial and class tensions since the 1960s.
