Every year, young adults leave the nest, couples divorce, foreigners immigrate and roommates separate, all helping drive economic growth when they furnish and refurbish their new homes. Under normal circumstances, each time a household is formed it adds about $145,000 to output that year as the spending ripples through the economy, estimates Mark Zandi, chief economist at Moody’s Analytics.
But with the poor job market and uncertain recovery, hundreds of thousands of Americans like Ms. [Hollis] Romanelli (and her boyfriend, who also lives with his parents) have tabled their moves. Even before the recession began, young people were leaving home later; now the bad economy has tethered them there indefinitely. Last year, just 950,000 new households were created. By comparison, about 1.3 million new households were formed in 2007, the year the recession began, according to Mr. Zandi. Ms. Romanelli, who lives in the room where she grew up in Branford, Conn., said, “I don’t really have much of a choice,” adding, “I don’t have the means to move out.”
