When people of color ask for raises, they're a lot less likely than white workers to get the salary bump they request, according to a new study by PayScale, a firm that analyzes compensation data.

Women of color, a group that includes African-Americans, Asians, Hispanics and other nonwhite people, are 19 percent less likely than white men to get the raise they ask for, according to the survey of about 160,000 respondents. Nonwhite men were 25 percent more likely to be turned down for a salary increase.

"Everyone's asking, but they're getting different answers," said Lydia Frank, vice president of content strategy at PayScale. "I think with the current climate in this country and the systemic racism that we've seen in other areas, I don't think it's terribly surprising."
