Young adults are key to boosting future household formation, but those households may look different than in previous generations. With declining marriage rates, households headed by married couples may no longer dominate the landscape
The number of 30-somethings who are married has fallen about 10 percent in the last decade, while the percentage of unmarried couples living together has nearly doubled from 7 percent to 13 percent, according to Gallup Analytics. The percentage of young adults who are single and live alone has also increased sharply, from 52 percent in 2004 to 64 percent in 2014.
