Nielsen and comScore survey US consumers through different methodologies, however they both try to paint a picture of the smartphone patterns of ownership and consumption.
I regularly report on comScore’s data as it’s published on a monthly basis. Nielsen offers updates on a quarterly basis but there is more detail.
The latest report (for Q2) shows smartphone shares by both platform and vendor. The following graph is a treemap built with the Nielsen data:
The same data is also plotted below as a pie chart:
I also added the latest comScore mobiLens data in the pie chart to the right.
Note that both surveys agree in the main on the largest platforms. The difference seems to be within a reasonable margin of error. The details available in the Nielsen data are perhaps also interesting. The various Android OEM shares as well as the division between Windows Mobile base and Windows Phone (7) base could provide some insight. Nielsen’s total Windows base adds up to 4.5% while comScore reckons on 4%. Within that total, Nielsen breaks out 3.2% for Windows Mobile and 1.3% for Windows Phone. Within the Windows Phone total, HTC and Samsung are shown as having 0.5% and Nokia 0.3%.
If we then use comScore’s figure for total smartphone users (110 million) then the data would suggest that there are 330k Lumias in use in the US. This would have been accummulated over a sales period of about four months.
