The average American household owns 1.9 vehicles, the survey shows, or slightly more than one vehicle per driver. Only 8 percent of households do not own a vehicle, while 61 percent own two or more. Most are cars or station wagons (116 million, or 57 percent). Pick-ups rank second in popularity, followed by SUVs. Minivans are fourth, numbering 18 million and accounting for 9 percent of vehicles. Americans also own 5 million motorcycles and 1.4 million recreational vehicles.
The NHTS confirms that couples with children own the 52 percent majority of SUVs. The married-with-kids demographic segment owns an even larger 61 percent of minivans. And, households with incomes of $100,000 or more own 21 percent of sport utility vehicles and only 9 percent of pick-up trucks and 13 percent of minivans.
