New income data from the Census Bureau, tabulated by former Census income specialists at the nonpartisan economic consulting firm Sentier Research, reveal that the three-and-a-half years of the Obama Presidency have done enormous harm to middle-class households.

In January 2009, the month President Obama entered the Oval Office and shortly before he signed his stimulus spending bill, median household income was $54,983. By June 2012, it had tumbled to $50,964, adjusted for inflation. (See the chart nearby.) That's $4,019 in lost real income, a little less than a month's income every year.

Unfair, you say, because Mr. Obama inherited a recession? Well, even if you start the analysis when the recession ended in June 2009, the numbers are dismal. Three years after the economy hit its trough, median household income is down $2,544, or nearly 5%.

Add the authors: "The overall decline since June 2009 was larger than the 2.6 percent decline that occurred" during the recession from December 2007 to June 2009. For household income, in other words, the Obama recovery has been worse than the Bush recession.

Consider the toll from America's corporate tax rate, which is the highest in the industrial world. A 2011 study by economists at the American Enterprise Institute found that because of the capital flight from the U.S. as a result of this high rate, "every additional dollar of tax revenue [from the corporate tax] leads to a $4 decrease in aggregate real wages." American workers would be the biggest beneficiaries of tax reform.

The new income data reveal other eye-opening trends. The group that has suffered the most during the Obama Presidency has been black Americans, whose real incomes have fallen by more than 11%.

Mr. Obama also likes to say that government workers like teachers are hurting and the private economy is doing "just fine." But the data indicate that over the past three years households with government workers saw their incomes decline less than households with private workers. The public-private pay gap is now wider than ever ($77,998 government versus $63,800).

Every age group has seen a decline in income—except the elderly. Those between the ages of 65 and 75 saw an average 6.5% gain in income, though most are not working and collect Medicare and Social Security.
