The unemployment rate is expected to climb to 8.7% next month, the lowest since October 2016.
A survey of more than 1,000 U.S. workers by the Economic Policy Institute found that workers earning between $30,000 and $60,000 had the highest unemployment rate at 4.4%, while those earning less than $30 was at 1.4%.
The survey also found that a majority of Americans are either unemployed or looking for work.
While only 10% of respondents were actively looking for a job, nearly half of those surveyed said they were “very likely” or “somewhat likely” to be unemployed, according to the study.
The economic outlook for 2018 is also uncertain.
The unemployment number is expected by economists to drop further, with the labor market showing signs of recovery from the depths of the Great Recession.
The number of Americans looking for jobs jumped last month, a sign of optimism about the future.
But some economists have raised concerns about the outlook for hiring and unemployment, saying that even if the economy recovers, a long-term labor shortage will remain.
The U.K. is among the nations that has the largest jobless population.
