Saudi Arabia has lagged the U.S. in oil production for the last four years, according to federal data compiled by University of Michigan economist Mark Perry.

Perry created a chart Saturday showing just how far behind Saudi oil production has trailed U.S. production. Rising U.S. production combined with OPEC policies drove crude oil prices down to new lows. Monday, a barrel of oil costs $46.26, while the same barrel would have sold for $109.04 in June 2014.
