While the partnerships have exploded in popularity, marriage numbers have continued a long decline in France, as across Europe. Just 250,000 French couples married in 2009, with fewer than four marriages per 1,000 residents; in 1970, almost 400,000 French couples wed.
Germany, too, has seen a similar plunge in marriage rates. In 2009, there were just over four marriages per 1,000 residents compared with more than seven per 1,000 in 1970. In the United States, the current rate is 6.8 per 1,000 residents, according to the Centers for Disease Control and Prevention.
