Working-class whites are the biggest beneficiaries of federal poverty-reduction programs, even though blacks and Hispanics have substantially higher rates of poverty, according to a new study released Thursday by the Center on Budget and Policy Priorities.

Government assistance and tax credits lifted 6.2 million working-class whites out of poverty in 2014, more than any other racial or ethnic demographic. Half of all working-age adults without college degrees lifted out of poverty by safety-net programs are white; nearly a quarter are black and a fifth are Hispanic.

The result does not simply reflect the fact that there are more white people in the country. The percentage of otherwise poor whites lifted from poverty by government safety-net programs is higher, at 44 percent, compared with 35 percent of otherwise poor minorities, the study concluded.

Among working-class minorities, blacks also benefit significantly from government programs, with 43 percent of otherwise poor blacks being lifted from poverty by the safety net. Only 28 percent of otherwise poor Hispanics were lifted from poverty by these programs.

"There is a perception out there that the safety net is only for minorities. … It's also quite important to whites, particularly the white working class," said Isaac Shapiro, a senior fellow at the Center on Budget and Policy Priorities and one of the report's authors.

The Center on Budget and Policy Priorities, a left-leaning think tank in Washington, analyzed working-age, non-college educated adult beneficiaries of more than a dozen government benefits, including food stamps, welfare, housing subsidies, tax credits, home energy assistance, school lunch programs, and Social Security.

Without the government programs, 24 percent of whites were poor, compared with 43 percent of blacks and 36 percent of Hispanics. After the programs, 13 percent of whites were poor, compared with 24 percent of blacks and 26 percent of Hispanics.

Working-class whites drawn to President Donald Trump's campaign may be particularly hard hit by the policies of the Trump administration and congressional Republicans, Shapiro said, including the push to dismantle President Barack Obama's health care reform law and changing the way food stamps and other programs for the poor are administered. The safety net appears to be even more critical, he said, in states with a large share of working-class whites, including the previously blue states of Wisconsin, Iowa and Ohio that flipped to Trump in 2016.

"A missing element of the political conversation has been the degree to which government programs are important to the working class in general, and the white working class in particular," Shapiro said.
