Marriage is in decline in almost every part of the world.
In the U.S., the marriage rate is roughly six per 1,000 people, a fall of nearly 60% since the 1970s.
But this is still high compared with most of the highly developed countries in the Organization for Economic Cooperation and Development, where the average marriage rate has dropped below four per 1,000.
Modern views on marriage are sharply divided: In a recent poll, two in five young adult Americans said that the institution has outlived its usefulness.
In Mesopotamian mythology, the first marriage was the heavenly union between Innana/Ishtar, the goddess of war and love, and her human lover, the shepherd Dumuzi.
