From 2000 to 2012–2016, the proportion of interracial or interethnic married-couple families increased across the United States, rising from 7.4 to 10.2 percent.
This change was different in different states, counties, and for particular racial/ethnic combinations. The subjugation of wives to husbands has been mandated by law and custom for thousands of years. However, as the movement for women's rights grew in power in the late 19th and early 20th centuries, wives gradually started to demand that they be treated as equals rather than as their husbands' property.

Because of how important marriage was, it was encouraged and safeguarded.
