NPD data: Back-to-school Mac sales up 16 percent, year-on-year

Data from the NPD group indicates that MacBook sales grew 16 percent year-on-year during the 10-week back-to-school period, measured from 4th July to Labor Day week. The most significant sales were seen during the last three weeks of the period, where sales were up 27 percent.

Overall Mac back-to-school market share climbed from 24.2% last year to 26.8% this year, while Windows fell from 72.3% to 64.8%. The most dramatic growth, though, was seen in low-cost Chrome OS devices, up from 0.2% in 2012 to 3.3% last year and 4.5% now.

It’s interesting to see Mac sales continue to climb despite competition from low-cost notebooks. IDC data last month showed that iOS market share declined slightly due to competition from low-cost Android devices.
