Answer:
Family life is changing. Two-parent households are on the decline in the United States as divorce, remarriage and cohabitation are on the rise. And families are smaller now, both due to the growth of single-parent households and the drop in fertility. Not only are Americans having fewer children, but the circumstances surrounding parenthood have changed. While in the early 1960s babies typically arrived within a marriage, today fully four-in-ten births occur to women who are single or living with a non-marital partner. At the same time that family structures have transformed, so has the role of mothers in the workplace – and in the home. As more moms have entered the labor force, more have become breadwinners – in many cases, primary breadwinners – in their families.
As a result of these changes, there is no longer one dominant family form in the U.S. Parents today are raising their children against a backdrop of increasingly diverse and, for many, constantly evolving family forms. By contrast, in 1960, the height of the post-World War II baby boom, there was one dominant family form. At that time 73% of all children were living in a family with two married parents in their first marriage. By 1980, 61% of children were living in this type of family, and today less than half (46%) are. The declining share of children living in what is often deemed a “traditional” family has been largely supplanted by the rising shares of children living with single or cohabiting parents.

<u>
Hypotheses</u>,<u> dependent</u> and <u>independent variables</u> form a set of tools that help us to create theories about natural phenomena.
The process for investigating a particular phenomenon in nature usually involves three levels. In the first level, observation of facts, phenomena, behaviors and activities takes place; at the second level, we have the hypotheses and finally, at the third level, theories, valid and sustainable hypotheses (those that have been tested) arise.
Dependent Variable are values (phenomena or facts) to be discovered or explained, by virtue of being influenced, determined or affected by the independent variable.
