On the surface, there’s one big glaring problem with these numbers. Actual sales data from the three largest carriers in the U.S. doesn’t seem to back up the comScore and NPD numbers. At all.
In the last quarter, the iPhone accounted for 78 percent of all smartphones sold through AT&T. On Verizon, the iPhone accounted for 51 percent of all smartphones sold. Sprint didn’t report their total smartphone sales numbers, only iPhone sales numbers, but estimates peg the iPhone percentage around 60 percent. The iPhone is not (yet) sold on the nation’s fourth largest carrier, T-Mobile.
That’s 51 percent of all smartphones sold on the nation’s largest carrier (Verizon). 78 percent of all smartphone sold on the nation’s number two carrier (AT&T). And 60 percent of all smartphones sold on the nation’s number three carrier (Sprint). Jay Yarow of Business Insider did the math: all together, the iPhone accounted for 63 percent of the smartphone sales in the past quarter on the big three carriers. The 63 percent number is close to the 59 percent estimated by Raymond James analyst Tavis McCourt last week, as reported by Eric Savitz for Forbes.
And if you believe the Yankee Group, the big three carriers account for roughly 80 percent of the overall U.S. smartphone market. This equates to almost exactly 50 percent of the overall smartphone market in the U.S. for Apple.
It’s hard to see how Android could control 61 percent of the market when there’s only 50 percent to spare after the actual numbers are calculated. Maybe Android is huge with undocumented workers. Undocumented workers who love taking surveys, mind you. But I digress…
And, of course, there are other smartphones out there from RIM, Microsoft, Nokia, and the like. Even giving Android the other 50 percent of the market would mean all of the other players equal zero percent. (Sadly, perhaps not that far off, actually.)
So how do the other guys get their numbers?
Surveys.
In comScore’s case, their MobiLens data comes from “an intelligent online survey of a nationally representative sample of mobile subscribers age 13 and older”. They don’t disclose the number of people surveyed, but you can bet it’s not a massive number (sure enough, it’s not, see update below). In NPD’s case, they survey 12,811 people.
Which numbers do you trust? Millions upon millions of actual sales reported in a legal manner by public companies or surveys of thousands of people?
Further, as Ethan Kaplan points out, “NPD and the like are incentive based surveys so naturally skew a certain way. Teens, college students, etc.” Several others have made this point over the past few days. The numbers comScore and NPD use in their statistically small surveys are likely skewed for a number of reasons. And again, now we have actual sales data that heavily suggests that’s the case.
