The incomes of typical Americans rose in 2015 by 5.2 percent, the first significant boost to middle-class pay since the end of the Great Recession and the fastest increase ever recorded by the federal government, the Census Bureau reported Tuesday.
In addition, the poverty rate fell by 1.2 percentage points, the steepest decline since 1968. There were 43.1 million Americans in poverty on the year, 3.5 million fewer than in 2014.
The share of Americans who lack health insurance continued a years-long decline, falling 1.3 percentage points, to 9.1 percent.
The numbers, from the government's annual report on income, poverty and health insurance, suggest the recovery from recession is finally beginning to lift the fortunes of large swaths of American workers and families. The Obama administration and its allies immediately hailed them in glowing terms.
"This exceeds the strong expectation that I already had," Jason Furman, chairman of Obama's Council of Economic Advisers, said in an interview, in which he called the income report the strongest ever from the Census Bureau. "The news here is the growth rates. I've read the last 21 reports, including this one. I have never seen one like this, in terms of, everything you look at is what you'd want to see or better."
GOP doubts numbers
Republicans discounted the improved outlook, saying the overall numbers remain weaker than they should be.
"Today's report is another disappointing confirmation that too many Americans are still struggling to provide for their families and reach their full potential. The federal government invests billions of dollars each year in programs to help low-income Americans - but more than 43 million people continue to live in poverty. It shouldn't be this way in America," House Ways and Means Committee Chairman Kevin Brady, R-Texas, said in a statement.
The numbers appear to run counter to a key narrative in the 2016 presidential campaign, pushed by Republican nominee Donald Trump, that America is in decline and working people's lives are getting worse. Trump frequently cites median income stagnation, relying on previous Census data, on the campaign trail. His campaign had not released a statement on the new Census report as of midday Tuesday.
Democrat Hillary Clinton has argued that the economy is improving under President Obama but that working families still need more help to get ahead. Her campaign said Tuesday that the Census numbers reinforce that view.
"These are really positive numbers by and large. They show real progress," said Jacob Leibenluft, a senior policy adviser to the Clinton campaign. He added: "This is definitely at odds with the picture that Trump provides."
Real median household income was $56,500 in 2015, the bureau reported, up from $53,700 in 2014. The gain was a combination of rising wages in the economy and low inflation.
