(NEWSER) – This is the time of year when people all around the country pack up their bags and head to the airport to visit family. Or at least that's the visual we all have. In reality, only 20% of adults in the US live more than a few hours' drive from their parents, the New York Times reports.

The Times has an in-depth look at where Americans live in relation to their parents and why. The information comes from a University of Michigan study in which researchers survey approximately 20,000 Americans over the age of 50 every two years. "The data reveal a country of close-knit families, with members of multiple generations leaning on one another for financial and practical support," the Times reports.

The takeaway: The typical American adult lives only 18 miles from his or her mom (with 18 miles being the median distance); 40% are within 5 miles.
