The retail industry is changing faster than ever these days, with most of the attention focused on innovation and technology. Between smartphones and tablets, social media and apps, consumers have seemingly unlimited choices of how and where they shop.

Shoppers still value the ability to see and touch the merchandise, and more than anything they prize the in-store shopping experience. In this study, RetailSails provides a comprehensive analysis of store productivity measures for a cross-section of over 200 American retailers which span 15 sectors, operate more than 200,000 stores and generate over $1.6 trillion in retail store sales.
