A new report issued by the Census Bureau revealed more Americans gained health insurance in 2014, but not much has changed in the poverty rate in the U.S.

According to the income, poverty and health insurance coverage report released on Wednesday, almost 9 million people obtained health insurance last year, bringing the number of uninsured Americans to 10.4 percent of the population. In 2013, 13.3 percent of Americans lacked health insurance. This suggests President Barack Obama's signature health care law, the Affordable Care Act, is helping many Americans.

The annual report also shows there has been no significant change in the income rate for the typical American household in 2014. For the fourth consecutive year, the poverty rate remained at 14.8 percent, which equates to almost 46.7 million people, the bureau said. Meanwhile, median household income in the United States was $53,660 in 2014.

"Despite decent employment growth in 2014, the persistent high unemployment yielded no improvements in wages and no improvement in the median incomes of working-age households or any reduction in poverty," said Lawrence Mishel, president of the Economic Policy Institute, to The New York Times.

"Anyone wondering why people in this country are feeling so ornery need look no further than this report," Mishel continued. "Wages have been broadly stagnant for a dozen years, and median household income peaked in 1999."

On the other hand, Republican Rep. Paul Ryan of Wisconsin said the data proves that Congress must stay committed to helping working class Americans get out of poverty.

"Rather than just treating the symptoms of poverty, our goal must be to help people move from welfare into work and self-sufficiency," Ryan said

Edward Welniak Jr., a Census Bureau statistician, said the income findings may have been affected by the fact that there were more "nonfamily households" in 2014.

These types of households "typically have much lower incomes than family households," Welniak said.

The report also found that the pay gap between working men and women has also remained stagnant since women still earn about 79 percent of what a man's income.
