Final answer:
The percentage of American children living in a household where the husband works for pay and the wife stays at home has decreased over the years.
Step-by-step explanation:
According to data from the U.S. Census, the percentage of American children living in a household where the husband works for pay and the wife stays at home has been decreasing over the years. In 1960, about 66 percent of households were headed by a married couple, but by 2010, that number dropped to 45 percent. While the specific percentage of children in such households is not mentioned, it can be inferred that the percentage would be lower than the overall percentage of married couple households.
