Apple has 361 retail stores with 40 more expected to open this year, 30 of those overseas. Over the next 5 years, Apple hopes to increase the number of its stores in China from the current 5 to 25. According to Fortune, the Apple Store locations average $2,033 in sales per square foot. The closest retailer to Apple was Tiffany as the luxury jeweler brought in sales of $2,974 per square foot in the same period. As Apple's retail empire has grown in the number of locations, the size of each store has also grown. Ten years ago, the average Apple Store had 6,000 square feet and today the average is 8,400.
As the chart from Wolf's report to clients shows, Apple has seen the business at its retail locations grow. Wolf says that the peaks in sales show the popularity of the Apple iPod, the launch of the Apple iPhone and the introduction of the Apple iPad. And as long as Apple continues to roll out new stores and new models of those products, the trend is likely to continue for some time.
