Donald Trump regularly tells his supporters that people are financially worse off now, at the end of President Obama's second term, than they were years ago, but a Gallup poll published Wednesday disagrees.

The portion of adults earning less than they made five years ago now stands at 20 percent, the Aug. 3-7 survey found. In 2013, that number was higher, at 28 percent.

Overall, 68 percent of respondents said they are earning more in 2016. Three years ago, just over half of Americans said they were making more money.

Those who work more than 40 hours a week are more likely to be better off now than those who work part-time. Nearly three-quarters of those working full-time reported making more money now compared to five years ago. Only half of part-time workers can say the same thing.

Workers making less now, when unemployment is down to 5 percent nationally, may have lost their jobs during the recession and forced to take a lower-paying job in order to have any income, resulting in lower wages in 2016.

The survey was conducted by telephone with a sampling from all 50 states and had a 6 percent margin of error.
