Going "home for the holidays" is probably only an 18-mile drive, if you're like the typical American. According to The New York Times, the average American only lives about 18 miles from his or her mother, and only 20 percent of Americans live more than a few hours from their parents by car.
"It speaks to a class divide in the population. Particularly as you go further down the socioeconomic scale, people are living pretty close to their parents, and this means they're able to provide help," economist Robert A. Pollak told The Upshot.
Families live closest in the Northeast and the South, and farthest apart on the West Coast and in the Mountain States.
