Customers spending more than Rs 300 (about US$4.50) per month account for 60 percent of the Indian mobile industry revenues, said CLSA.
In other words, 165 million customers drive 60 percent of total industry revenues. If there are now about a billion total Indian mobile accounts active, then it also is the case that 17 percent of accounts drive 60 percent of revenue.
That would be a classic demonstration of the Pareto distribution, often called the “80.20 rule,” where a disproportionate amount of results is driven by a relatively small number of instances.
