Apple is making record profits, so it's no surprise that all that money comes from people buying its products. A survey by CNBC has found that half of all American households own at least one Apple device, and the average Apple-buying household has a total of three. The survey collected answers from 836 Americans over both landline and cellphone, asking for demographic information and ownership rates for Apple products, including traditional computers, tablets, phones, and other devices. About 50 percent of households reported owning at least one product, and 63 percent of people between 18 and 49 reported owning one. That number was still surprisingly high for older Americans: 50 percent of people between 50 and 64 owned one, as did 26 percent of those 65 or older.

As might be expected, ownership is strongly correlated with income. Only 28 percent of households that make less than $30,000 a year own an Apple product, as opposed to 77 percent of those making more than $75,000. Of course, it's important to keep in mind that we don't have similar survey numbers for non-Apple devices, so we wouldn't mark down Apple as the device of choice for the wealthy just yet. Families with children are also markedly more likely to own an Apple device. We'd be wary of drawing too many conclusions about Apple per se without seeing similar numbers for PCs, tablets, and phones as a class, but this survey certainly solidifies Apple's place as one of the dominant makers of consumer electronics.
