The Census Bureau reported last week that middle-class income is continuing to shrink, top-tier incomes are growing and those at the bottom remained about the same. It wasn't shocking news, confirming what dozens of independent studies have shown.
What does come as a surprise is what politicians regard as middle income.
On Friday, Republican presidential nominee Mitt Romney said "middle income is $200,000 to $250,000 and less."
That's about where President Barack Obama has drawn the line, too. He wants to raise the income tax rate on "the wealthy" who earn more than that.
A better place to begin the discussion is at true middle income, where half earn more and half earn less. The Census Bureau puts median household income for 2011, adjusted for inflation, at $50,054. That's down $780 in inflation-adjusted dollars from 2010.
Neither Mr. Romney nor Mr. Obama has had to live within the boundaries of that income for a very long time, if ever.
The Census Bureau's annual report on poverty, annual income and health insurance is the most comprehensive breakdowns of the financial conditions of people in the United States.
Economists were most surprised by the news in the report that poverty stayed relatively the same. In 2010, 15.1 percent of the nation's population was in poverty, and last year it was 15 percent, with 46.2 million people at the poverty level.
