To differentiate customer segments, Monitor Group has used “action segmentation,” a market analysis strategy that draws on statistical data from a customer survey with several thousand samples and wide coverage. This methodology identifies multiple consumer segments to help companies address core organizational issues, achieve a well-designed marketing mix, reach growth targets, and more effectively engage their market. In the case of China’s middle class, Monitor focused on purchasing behavior and demographic features, rather than income, as the key measures for understanding the middle class.
