All kinds of ratios help illustrate the wealth gap in the United States.


Here is another one: 1,200 to 1. It measures the difference between the pay of fast-food company CEOs and their workers, according to a report that is to be released today, Bloomberg Businessweek reported.


The typical void between the average pay of CEOs and their workers is 331 to 1, Bloomberg Businessweek said.


The report from Demos, a public policy organization, said that fast-food CEOs are some of the highest-paid executives in America, with an average compensation of $26.7 million in 2012.


Fast-food workers are the lowest-paid. Their average hourly wage is $9.09.


The companies cited include McDonald's Corp., Chipotle Mexican Grill Inc., Starbucks Corp., Yum! Brands Inc. (owner of KFC, Pizza Hut, and Taco Bell) and six others.


Catherine Ruetschlin, the author of the report, said she didn't want to call out specific executives (though McDonald's, the biggest fast-food chain by sales, gets extra attention.) Nor is she advocating a specific increase in wages for workers.


"It's not about how much a CEO makes or how little the workers do; it's the relationship between the two," she said.
