The U.S. economy is showing signs of finally bottoming out. New census data show that Americans are on the move again after record numbers had stayed put, and fewer young adults are living with their parents.

About 12 percent of the nation's population, or 36.5 million, moved to a new home in the past year. That's up from a low of 11.6 percent in 2011.

Roughly 5.6 million adults ages 25-34, or 13.6 percent, lived with Mom and Dad in the past year, a decrease from 14.2 percent in the previous year.

The increases in mobility coincide with modest improvements in the job market as well as rising college enrollment.

Steep declines in the births now appear to be leveling off, while poverty is slowing.
