(WALL STREET JOURNAL) — More seniors are living with their children these days, but don’t blame the slow U.S. economy. Blame demographics.

Since the mid-1990s, the share of people 65 years old and over living with their children or other relatives has risen from around 6.6% to 7.3% in 2013, according to an analysis of data from the Census Bureau’s Current Population Survey by Jed Kolko, chief economist at Trulia, a real-estate listings site.

According to the American Community Survey — a bigger Census study with a sample size large enough to analyze specific demographic groups — 9% of seniors lived in a household headed by their children, children-in-law or other relatives besides their spouses in 2012. Another 2% lived with people they weren’t related to, while 3% lived in places like nursing homes. The rest, about 85%, lived in their own homes.
