The numbers seem overwhelming: an ever-increasing number of visitors to Apple’s retail stores, a larger market share, and millions of computers and iPods sold each year. But do those figures mean that Apple’s retail stores are actually growing more crowded? Not according to figures derived from Apple’s financial reports. According to Apple, the number of visitors has increased from 2.1 million in the third quarter of 2002, to 21.9 million in the same quarter of 2007. But at the same time, the average number of open stores has also increased, from 30 in Q3 2002 to 180 in the same quarter of 2007. Based on those figures, the number of per-store visitors has remained fairly stable lately, within a narrow range of from 112,000 to 126,000 visitors per quarter.
There have been two large spikes in visitor traffic during the past five years, both associated with the holiday season in 2006 and 2007.Prior to Q2 2005, the number of visitors had zig-zagged up and down twice, but then slowly increased over four quarters. Now it appears that Apple’s yearly plan to open 35 to 40 retail stores is keeping up with the cutomers’ demand for the company’s products and, especially important, store services such as One to One, ProCare and the Genius Bar.
Looking at the situation another way, adding more stores doesn’t decrease the average number of visitors to the stores, indicating a continuing supply of people for the next retail stores that open.
[Follow-up: Again, this is all based on average visitor figures, which completely masks the congestion that occurs at the flagship stores and other locations, and leaves fewer visitors at yet other stores. The comments more accurately reflect daily visitor levels.]
