The gap in income between the 10% who make the most and those who make the least in the U.S. has continued to widen since 1970, according to a new study by the Pew Research Center.

Why it matters: The income disparities are strongly tied to other inequalities — such as education — among racial groups, which often most acutely impact immigrants.
